This is a complete list of the parameters which can be set (e.g. via the MAVLink protocol) to control vehicle behaviour. They are stored in persistent storage on the vehicle.

This list is automatically generated from the latest ardupilot source code, and so may contain parameters which are not yet in the stable released versions of the code.

ArduPlane Parameters

FORMAT_VERSION: Eeprom format version number

Note: This parameter is for advanced users

This value is incremented when changes are made to the eeprom format

AUTOTUNE_LEVEL: Autotune level

Level of aggressiveness of pitch and roll PID gains. Lower values result in a 'softer' tune. Level 6 recommended for most planes. A value of 0 means to keep the current values of RMAX and TCONST for the controllers, tuning only the PID values

Increment	Range
1	0 to 10

AUTOTUNE_OPTIONS: Autotune options bitmask

Note: This parameter is for advanced users

Fixed Wing Autotune specific options. Useful on QuadPlanes with higher INS_GYRO_FILTER settings to prevent these filter values from being set too aggressively during Fixed Wing Autotune.

Bitmask
Bit Meaning 0 Disable FLTD update by Autotune 1 Disable FLTT update by Autotune

GCS_PID_MASK: GCS PID tuning mask

Note: This parameter is for advanced users

bitmask of PIDs to send MAVLink PID_TUNING messages for

Bitmask
Bit Meaning 0 Roll 1 Pitch 2 Yaw 3 Steering 4 Landing 5 AccZ

KFF_RDDRMIX: Rudder Mix

Amount of rudder to add during aileron movement. Increase if nose initially yaws away from roll. Reduces adverse yaw.

Increment	Range
0.01	0 to 1

KFF_THR2PTCH: Throttle to Pitch Mix

Note: This parameter is for advanced users

Pitch up to add in proportion to throttle. 100% throttle will add this number of degrees to the pitch target.

Increment	Range
0.01	-5 to 5

STAB_PITCH_DOWN: Low throttle pitch down trim

Note: This parameter is for advanced users

Degrees of down pitch added when throttle is below TRIM_THROTTLE in FBWA and AUTOTUNE modes. Scales linearly so full value is added when THR_MIN is reached. Helps to keep airspeed higher in glides or landing approaches and prevents accidental stalls. 2 degrees recommended for most planes.

Increment	Range	Units
0.1	0 to 15	degrees

ALT_SLOPE_MIN: Altitude slope minimum

Note: This parameter is for advanced users

This controls the minimum altitude change for a waypoint before an altitude slope will be used instead of an immediate altitude change. The default value is 15 meters, which helps to smooth out waypoint missions where small altitude changes happen near waypoints. If you don't want altitude slopes to be used in missions then you can set this to zero, which will disable altitude slope calculations. Otherwise you can set it to a minimum number of meters of altitude error to the destination waypoint before an altitude slope will be used to change altitude.

Increment	Range	Units
1	0 to 1000	meters

ALT_SLOPE_MAXHGT: Altitude slope maximum height

Note: This parameter is for advanced users

This controls the height above the altitude slope the plane may be before rebuilding it. This is useful for smoothing out an auto-takeoff.

Increment	Range	Units
1	0 to 100	meters

STICK_MIXING: Stick Mixing

Note: This parameter is for advanced users

When enabled, this adds user stick input to the control surfaces in auto modes, allowing the user to have some degree of flight control without changing modes. There are 3 types of stick mixing available. If you set STICK_MIXING to 1 or 4 then it will use "fly by wire" mixing. 4 will provide roll and yaw control, while 1 also provides FBW-A style pitch control. If you set STICK_MIXING to 3 then it will apply to the yaw while in quadplane modes only, such as while doing an automatic VTOL takeoff or landing. WARNING: FBW-A pitch control does not offer flight envelope protections. Prolonged pitch inputs in mode 1 can result in a stall or overspeed condition, and should be avoided.

Values
Value Meaning 0 Disabled 1 FBW style 3 VTOL Yaw only 4 FBW style (no pitch)

TKOFF_THR_MINSPD: Takeoff throttle min speed

Minimum GPS ground speed in m/s used by the speed check that un-suppresses throttle in auto-takeoff. This can be be used for catapult launches where you want the motor to engage only after the plane leaves the catapult, but it is preferable to use the TKOFF_THR_MINACC and TKOFF_THR_DELAY parameters for catapult launches due to the errors associated with GPS measurements. For hand launches with a pusher prop it is strongly advised that this parameter be set to a value no less than 4 m/s to provide additional protection against premature motor start. Note that the GPS velocity will lag the real velocity by about 0.5 seconds. The ground speed check is delayed by the TKOFF_THR_DELAY parameter.

Increment	Range	Units
0.1	0 to 30	meters per second

TKOFF_THR_MINACC: Takeoff throttle min acceleration

Minimum forward acceleration in m/s/s before arming the ground speed check in auto-takeoff. This is meant to be used for hand launches. Setting this value to 0 disables the acceleration test which means the ground speed check will always be armed which could allow GPS velocity jumps to start the engine. For hand launches and bungee launches this should be set to around 15. Also see TKOFF_ACCEL_CNT parameter for control of full "shake to arm".

Increment	Range	Units
0.1	0 to 30	meters per square second

TKOFF_THR_DELAY: Takeoff throttle delay

This parameter sets the time delay (in 1/10ths of a second) that the ground speed check is delayed after the forward acceleration check controlled by TKOFF_THR_MINACC has passed. For hand launches with pusher propellers it is essential that this is set to a value of no less than 2 (0.2 seconds) to ensure that the aircraft is safely clear of the throwers arm before the motor can start. For bungee launches a larger value can be used (such as 30) to give time for the bungee to release from the aircraft before the motor is started.

Increment	Range	Units
1	0 to 127	deciseconds

TKOFF_THR_MAX_T: Takeoff throttle maximum time

This sets the time that maximum throttle will be forced during a fixed wing takeoff.

Increment	Range	Units
0.5	0 to 10	seconds

TKOFF_THR_MIN: Takeoff minimum throttle

The minimum throttle to use in takeoffs in AUTO and TAKEOFF flight modes, when TKOFF_OPTIONS bit 0 is set. Also, the minimum throttle to use in a quadpane forward transition. This can be useful to ensure faster takeoffs or transitions on aircraft where the normal throttle control leads to a slow takeoff or transition. It is used when it is larger than THR_MIN, otherwise THR_MIN is used instead.

Increment	Range	Units
1	0 to 100	percent

TKOFF_THR_IDLE: Takeoff idle throttle

The idle throttle to hold after arming and before a takeoff. Applicable in TAKEOFF and AUTO modes.

Increment	Range	Units
1	0 to 100	percent

TKOFF_OPTIONS: Takeoff options

Note: This parameter is for advanced users

This selects the mode of the takeoff in AUTO and TAKEOFF flight modes.

Bitmask
Bit Meaning 0 When unset the maximum allowed throttle is always used (THR_MAX or TKOFF_THR_MAX) during takeoff. When set TECS is allowed to operate between a minimum (THR_MIN or TKOFF_THR_MIN) and a maximum (THR_MAX or TKOFF_THR_MAX) limit. Applicable only when using an airspeed sensor.

TKOFF_TDRAG_ELEV: Takeoff tail dragger elevator

This parameter sets the amount of elevator to apply during the initial stage of a takeoff. It is used to hold the tail wheel of a taildragger on the ground during the initial takeoff stage to give maximum steering. This option should be combined with the TKOFF_TDRAG_SPD1 option and the GROUND_STEER_ALT option along with tuning of the ground steering controller. A value of zero means to bypass the initial "tail hold" stage of takeoff. Set to zero for hand and catapult launch. For tail-draggers you should normally set this to 100, meaning full up elevator during the initial stage of takeoff. For most tricycle undercarriage aircraft a value of zero will work well, but for some tricycle aircraft a small negative value (say around -20 to -30) will apply down elevator which will hold the nose wheel firmly on the ground during initial acceleration. Only use a negative value if you find that the nosewheel doesn't grip well during takeoff. Too much down elevator on a tricycle undercarriage may cause instability in steering as the plane pivots around the nosewheel. Add down elevator 10 percent at a time.

Increment	Range	Units
1	-100 to 100	percent

TKOFF_TDRAG_SPD1: Takeoff tail dragger speed1

This parameter sets the airspeed at which to stop holding the tail down and transition to rudder control of steering on the ground. When TKOFF_TDRAG_SPD1 is reached the pitch of the aircraft will be held level until TKOFF_ROTATE_SPD is reached, at which point the takeoff pitch specified in the mission will be used to "rotate" the pitch for takeoff climb. Set TKOFF_TDRAG_SPD1 to zero to go straight to rotation. This should be set to zero for hand launch and catapult launch. It should also be set to zero for tricycle undercarriages unless you are using the method above to gently hold the nose wheel down. For tail dragger aircraft it should be set just below the stall speed.

Increment	Range	Units
0.1	0 to 30	meters per second

TKOFF_ROTATE_SPD: Takeoff rotate speed

This parameter sets the airspeed at which the aircraft will "rotate", setting climb pitch specified in the mission. If TKOFF_ROTATE_SPD is zero then the climb pitch will be used as soon as takeoff is started. For hand launch and catapult launches a TKOFF_ROTATE_SPD of zero should be set. For all ground launches TKOFF_ROTATE_SPD should be set above the stall speed, usually by about 10 to 30 percent. During the run, use TKOFF_GND_PITCH to keep the aircraft on the runway while below this airspeed.

Increment	Range	Units
0.1	0 to 30	meters per second

TKOFF_THR_SLEW: Takeoff throttle slew rate

This parameter sets the slew rate for the throttle during auto takeoff. When this is zero the THR_SLEWRATE parameter is used during takeoff. For rolling takeoffs it can be a good idea to set a lower slewrate for takeoff to give a slower acceleration which can improve ground steering control. The value is a percentage throttle change per second, so a value of 20 means to advance the throttle over 5 seconds on takeoff. Values below 20 are not recommended as they may cause the plane to try to climb out with too little throttle. A value of -1 means no limit on slew rate in takeoff.

Increment	Range	Units
1	-1 to 127	percent per second

TKOFF_PLIM_SEC: Takeoff pitch limit reduction

Note: This parameter is for advanced users

This parameter reduces the pitch minimum limit of an auto-takeoff just a few seconds before it reaches the target altitude. This reduces overshoot by allowing the flight controller to start leveling off a few seconds before reaching the target height. When set to zero, the mission pitch min is enforced all the way to and through the target altitude, otherwise the pitch min slowly reduces to zero in the final segment. This is the pitch_min, not the demand. The flight controller should still be commanding to gain altitude to finish the takeoff but with this param it is not forcing it higher than it wants to be.

Increment	Range	Units
0.5	0 to 10	seconds

TKOFF_FLAP_PCNT: Takeoff flap percentage

Note: This parameter is for advanced users

The amount of flaps (as a percentage) to apply in automatic takeoff

Increment	Range	Units
1	0 to 100	percent

LEVEL_ROLL_LIMIT: Level flight roll limit

This controls the maximum bank angle in degrees during flight modes where level flight is desired, such as in the final stages of landing, and during auto takeoff. This should be a small angle (such as 5 degrees) to prevent a wing hitting the runway during takeoff or landing. Setting this to zero will completely disable heading hold on auto takeoff while below 5 meters and during the flare portion of a final landing approach.

Increment	Range	Units
1	0 to 45	degrees

USE_REV_THRUST: Bitmask for when to allow negative reverse thrust

Note: This parameter is for advanced users

This controls when to use reverse thrust. If set to zero then reverse thrust is never used. If set to a non-zero value then the bits correspond to flight stages where reverse thrust may be used. The most commonly used value for USE_REV_THRUST is 2, which means AUTO_LAND only. That enables reverse thrust in the landing stage of AUTO mode. Another common choice is 1, which means to use reverse thrust in all auto flight stages. Reverse thrust is always used in MANUAL mode if enabled with THR_MIN < 0. In non-autothrottle controlled modes, if reverse thrust is not used, then THR_MIN is effectively set to 0 for that mode.

Bitmask
Bit Meaning 0 AUTO_ALWAYS 1 AUTO_LAND 2 AUTO_LOITER_TO_ALT 3 AUTO_LOITER_ALL 4 AUTO_WAYPOINTS 5 LOITER 6 RTL 7 CIRCLE 8 CRUISE 9 FBWB 10 GUIDED 11 AUTO_LANDING_PATTERN 12 FBWA 13 ACRO 14 STABILIZE 15 THERMAL

ALT_OFFSET: Altitude offset

Note: This parameter is for advanced users

This is added to the target altitude in automatic flight. It can be used to add a global altitude offset to a mission

Increment	Range	Units
1	-32767 to 32767	meters

WP_RADIUS: Waypoint Radius

Defines the maximum distance from a waypoint that when crossed indicates the waypoint may be complete. To avoid the aircraft looping around the waypoint in case it misses by more than the WP_RADIUS an additional check is made to see if the aircraft has crossed a "finish line" passing through the waypoint and perpendicular to the flight path from the previous waypoint. If that finish line is crossed then the waypoint is considered complete. Note that the navigation controller may decide to turn later than WP_RADIUS before a waypoint, based on how sharp the turn is and the speed of the aircraft. It is safe to set WP_RADIUS much larger than the usual turn radius of your aircraft and the navigation controller will work out when to turn. If you set WP_RADIUS too small then you will tend to overshoot the turns.

Increment	Range	Units
1	1 to 32767	meters

WP_MAX_RADIUS: Waypoint Maximum Radius

Sets the maximum distance to a waypoint for the waypoint to be considered complete. This overrides the "cross the finish line" logic that is normally used to consider a waypoint complete. For normal AUTO behaviour this parameter should be set to zero. Using a non-zero value is only recommended when it is critical that the aircraft does approach within the given radius, and should loop around until it has done so. This can cause the aircraft to loop forever if its turn radius is greater than the maximum radius set.

Increment	Range	Units
1	0 to 32767	meters

WP_LOITER_RAD: Waypoint Loiter Radius

Defines the distance from the waypoint center, the plane will maintain during a loiter. If you set this value to a negative number then the default loiter direction will be counter-clockwise instead of clockwise. If this value is too close to zero, the achieved loiter radius will be determined by ROLL_LIMIT_DEG.

Increment	Range	Units
1	-32767 to 32767	meters

RTL_RADIUS: RTL loiter radius

Defines the radius of the loiter circle when in RTL mode. If this is zero then WP_LOITER_RAD is used. If the radius is negative then a counter-clockwise is used. If positive then a clockwise loiter is used. For quadplanes with Q_RTL_MODE set to 1 (Enabled), this value is used to set the minimum radius at which the plane will transition from fixed-wing to VTOL mode for landing.

Increment	Range	Units
1	-32767 to 32767	meters

STALL_PREVENTION: Enable stall prevention

Enables roll limits at low airspeed in roll limiting flight modes. Roll limits based on aerodynamic load factor in turns and scale on AIRSPEED_MIN that must be set correctly. Without airspeed sensor, uses synthetic airspeed from wind speed estimate that may both be inaccurate.

Values
Value Meaning 0 Disabled 1 Enabled

AIRSPEED_CRUISE: Target cruise airspeed

Target cruise airspeed in m/s in automatic throttle modes. Value is as an indicated (calibrated/apparent) airspeed.

Units
meters per second

AIRSPEED_MIN: Minimum Airspeed

Minimum airspeed demanded in automatic throttle modes. Should be set to 20% higher than level flight stall speed.

Increment	Range	Units
1	5 to 100	meters per second

AIRSPEED_MAX: Maximum Airspeed

Maximum airspeed demanded in automatic throttle modes. Should be set slightly less than level flight speed at THR_MAX and also at least 50% above AIRSPEED_MIN to allow for accurate TECS altitude control.

Increment	Range	Units
1	5 to 100	meters per second

AIRSPEED_STALL: Stall airspeed

If stall prevention is enabled this speed is used to calculate the minimum airspeed while banking. It is also used during landing final as the minimum airspeed that can be demanded by the TECS, which allows using TECS_LAND_ARSPD or LAND_PF_ARSPD to achieve landings slower than AIRSPEED_MIN. If this is set to 0 then the stall speed is assumed to be the minimum airspeed speed. Typically set slightly higher then true stall speed.

Range	Units
5 to 75	meters per second

FBWB_ELEV_REV: Fly By Wire elevator reverse

Reverse sense of elevator in FBWB and CRUISE modes. When set to 0 up elevator (pulling back on the stick) means to lower altitude. When set to 1, up elevator means to raise altitude.

Values
Value Meaning 0 Disabled 1 Enabled

TERRAIN_FOLLOW: Use terrain following

This enables terrain following for CRUISE mode, FBWB mode, RTL and for rally points. To use this option you also need to set TERRAIN_ENABLE to 1, which enables terrain data fetching from the GCS, and you need to have a GCS that supports sending terrain data to the aircraft. When terrain following is enabled then CRUISE and FBWB mode will hold height above terrain rather than height above home. In RTL the return to launch altitude will be considered to be a height above the terrain. Rally point altitudes will be taken as height above the terrain. This option does not affect mission items, which have a per-waypoint flag for whether they are height above home or height above the terrain. To use terrain following missions you need a ground station which can set the waypoint type to be a terrain height waypoint when creating the mission.

Bitmask
Bit Meaning 0 Enable all modes 1 FBWB 2 Cruise 3 Auto 4 RTL 5 Avoid_ADSB 6 Guided 7 Loiter 8 Circle 9 QRTL 10 QLand 11 Qloiter 12 AUTOLAND

TERRAIN_LOOKAHD: Terrain lookahead

This controls how far ahead the terrain following code looks to ensure it stays above upcoming terrain. A value of zero means no lookahead, so the controller will track only the terrain directly below the aircraft. The lookahead will never extend beyond the next waypoint when in AUTO mode.

Range	Units
0 to 10000	meters

FBWB_CLIMB_RATE: Fly By Wire B altitude change rate

This sets the rate in m/s at which FBWB and CRUISE modes will change its target altitude for full elevator deflection. Note that the actual climb rate of the aircraft can be lower than this, depending on your airspeed and throttle control settings. If you have this parameter set to the default value of 2.0, then holding the elevator at maximum deflection for 10 seconds would change the target altitude by 20 meters.

Increment	Range	Units
0.1	1 to 10	meters per second

THR_MIN: Minimum Throttle

Minimum throttle percentage used in all modes except manual, provided THR_PASS_STAB is not set. Negative values allow reverse thrust if hardware supports it.

Increment	Range	Units
1	-100 to 100	percent

THR_MAX: Maximum Throttle

Maximum throttle percentage used in all modes except manual, provided THR_PASS_STAB is not set.

Increment	Range	Units
1	0 to 100	percent

TKOFF_THR_MAX: Maximum Throttle for takeoff

Note: This parameter is for advanced users

The maximum throttle setting during automatic takeoff. If this is zero then THR_MAX is used for takeoff as well.

Increment	Range	Units
1	0 to 100	percent

THR_SLEWRATE: Throttle slew rate

Maximum change in throttle percentage per second. Lower limit based on 1 microsend of servo increase per loop. Divide SCHED_LOOP_RATE by approximately 10 to determine minimum achievable value.

Increment	Range	Units
1	0 to 127	percent per second

FLAP_SLEWRATE: Flap slew rate

Note: This parameter is for advanced users

maximum percentage change in flap output per second. A setting of 25 means to not change the flap by more than 25% of the full flap range in one second. A value of 0 means no rate limiting.

Increment	Range	Units
1	0 to 100	percent per second

THR_SUPP_MAN: Throttle suppress manual passthru

Note: This parameter is for advanced users

When throttle is suppressed in auto mode it is normally forced to zero. If you enable this option, then while suppressed it will be manual throttle. This is useful on petrol engines to hold the idle throttle manually while waiting for takeoff

Values
Value Meaning 0 Disabled 1 Enabled

THR_PASS_STAB: Throttle passthru in stabilize

Note: This parameter is for advanced users

If this is set then when in STABILIZE, FBWA or ACRO modes the throttle is a direct passthru from the transmitter. This means the THR_MIN and THR_MAX settings are not used in these modes. This is useful for petrol engines where you setup a throttle cut switch that suppresses the throttle below the normal minimum.

Values
Value Meaning 0 Disabled 1 Enabled

THR_FAILSAFE: Throttle and RC Failsafe Enable

0 disables the failsafe. 1 enables failsafe on loss of RC input. This is detected either by throttle values below THR_FS_VALUE, loss of receiver valid pulses/data, or by the FS bit in receivers that provide it, like SBUS. A programmable failsafe action will occur and RC inputs, if present, will be ignored. A value of 2 means that the RC inputs won't be used when RC failsafe is detected by any of the above methods, but it won't trigger an RC failsafe action.

Values
Value Meaning 0 Disabled 1 Enabled 2 EnabledNoFailsafe

THR_FS_VALUE: Throttle Failsafe Value

The PWM level on the throttle input channel below which throttle failsafe triggers. Note that this should be well below the normal minimum for your throttle channel.

Increment	Range
1	925 to 2200

TRIM_THROTTLE: Throttle cruise percentage

Target percentage of throttle to apply for flight in automatic throttle modes and throttle percentage that maintains AIRSPEED_CRUISE. Caution: low battery voltages at the end of flights may require higher throttle to maintain airspeed.

Increment	Range	Units
1	0 to 100	percent

THROTTLE_NUDGE: Throttle nudge enable

When enabled, this uses the throttle input in auto-throttle modes to 'nudge' the throttle or airspeed to higher or lower values. When you have an airspeed sensor the nudge affects the target airspeed, so that throttle inputs above 50% will increase the target airspeed from AIRSPEED_CRUISE up to a maximum of AIRSPEED_MAX. When no airspeed sensor is enabled the throttle nudge will push up the target throttle for throttle inputs above 50%.

Values
Value Meaning 0 Disabled 1 Enabled

FS_SHORT_ACTN: Short failsafe action

The action to take on a short (FS_SHORT_TIMEOUT) failsafe event. A short failsafe event can be triggered either by loss of RC control (see THR_FS_VALUE) or by loss of GCS control (see FS_GCS_ENABL). If in CIRCLE or RTL mode this parameter is ignored. A short failsafe event in stabilization and manual modes will cause a change to CIRCLE mode if FS_SHORT_ACTN is 0 or 1, a change to FBWA mode with zero throttle if FS_SHORT_ACTN is 2, and a change to FBWB mode if FS_SHORT_ACTN is 4. In all other modes (AUTO, GUIDED and LOITER) a short failsafe event will cause no mode change if FS_SHORT_ACTN is set to 0, will cause a change to CIRCLE mode if set to 1, will change to FBWA mode with zero throttle if set to 2, or will change to FBWB if set to 4. Please see the documentation for FS_LONG_ACTN for the behaviour after FS_LONG_TIMEOUT seconds of failsafe. This parameter only applies to failsafes during fixed wing modes. Quadplane modes will switch to QLAND unless Q_OPTIONS bit 5(QRTL) or 20(RTL) are set.

Values
Value Meaning 0 CIRCLE/no change(if already in AUTO|GUIDED|LOITER) 1 CIRCLE 2 FBWA at zero throttle 3 Disable 4 FBWB

FS_SHORT_TIMEOUT: Short failsafe timeout

The time in seconds that a failsafe condition has to persist before a short failsafe event will occur. This defaults to 1.5 seconds

Increment	Range	Units
0.5	1 to 100	seconds

FS_LONG_ACTN: Long failsafe action

The action to take on a long (FS_LONG_TIMEOUT seconds) failsafe event. If the aircraft was in a stabilization or manual mode when failsafe started and a long failsafe occurs then it will change to RTL mode if FS_LONG_ACTN is 0 or 1, and will change to FBWA if FS_LONG_ACTN is set to 2. If the aircraft was in an auto mode (such as AUTO or GUIDED) when the failsafe started then it will continue in the auto mode if FS_LONG_ACTN is set to 0, will change to RTL mode if FS_LONG_ACTN is set to 1 and will change to FBWA mode if FS_LONG_ACTN is set to 2. If FS_LONG_ACTN is set to 3, the parachute will be deployed (make sure the chute is configured and enabled). If FS_LONG_ACTN is set to 4 the aircraft will switch to mode AUTO with the current waypoint if it is not already in mode AUTO, unless it is in the middle of a landing sequence. If FS_LONG_ACTN is set to 5, will switch to AUTOLAND mode if possible, otherwise RTL mode. This parameter only applies to failsafes during fixed wing modes. Quadplane modes will switch to QLAND unless Q_OPTIONS bit 5 (QRTL) or 20(RTL) are set.

Values
Value Meaning 0 Continue 1 ReturnToLaunch 2 Glide 3 Deploy Parachute 4 Auto 5 AUTOLAND

FS_LONG_TIMEOUT: Long failsafe timeout

The time in seconds that a failsafe condition has to persist before a long failsafe event will occur. This defaults to 5 seconds.

Increment	Range	Units
0.5	1 to 300	seconds

FS_GCS_ENABL: GCS failsafe enable

Enable ground control station telemetry failsafe. Failsafe will trigger after FS_LONG_TIMEOUT seconds of no MAVLink heartbeat messages. There are three possible enabled settings. Setting FS_GCS_ENABL to 1 means that GCS failsafe will be triggered when the aircraft has not received a MAVLink HEARTBEAT message. Note that heartbeat tracking only becomes active after having received the first heartbeat from the MAV_GCS_SYSID primary GCS system. Setting FS_GCS_ENABL to 2 means that GCS failsafe will be triggered on either a loss of HEARTBEAT messages, or a RADIO_STATUS message from a MAVLink enabled telemetry adio indicating that the primary ground station is not receiving status updates from the aircraft, which is indicated by the RADIO_STATUS.remrssi field being zero (this may happen if you have a one way link due to asymmetric noise on the ground station and aircraft radios).Setting FS_GCS_ENABL to 3 means that GCS failsafe will be triggered by Heartbeat(like option one), but only in AUTO mode. WARNING: Enabling this option opens up the possibility of your plane going into failsafe mode and running the motor on the ground it it loses contact with your ground station. If this option is enabled on an electric plane then you should enable ARMING_REQUIRED.

MIXING_GAIN: Mixing Gain

The gain for the Vtail and elevon output mixers. The default is 0.5, which ensures that the mixer doesn't saturate, allowing both input channels to go to extremes while retaining control over the output. Hardware mixers often have a 1.0 gain, which gives more servo throw, but can saturate. If you don't have enough throw on your servos with VTAIL_OUTPUT or ELEVON_OUTPUT enabled then you can raise the gain using MIXING_GAIN. The mixer allows outputs in the range 900 to 2100 microseconds.

Range
0.5 to 1.2

RUDDER_ONLY: Rudder only aircraft

Enable rudder only mode. The rudder will control attitude in attitude controlled modes (such as FBWA). You should setup your transmitter to send roll stick inputs to the RCMAP_YAW channel (normally channel 4). The rudder servo should be attached to the RCMAP_YAW channel as well. Note that automatic ground steering will be disabled for rudder only aircraft. You should also set KFF_RDDRMIX to 1.0. You will also need to setup the YAW2SRV_DAMP yaw damping appropriately for your aircraft. A value of 0.5 for YAW2SRV_DAMP is a good starting point.

Values
Value Meaning 0 Disabled 1 Enabled

MIXING_OFFSET: Mixing Offset

The offset for the Vtail and elevon output mixers, as a percentage. This can be used in combination with MIXING_GAIN to configure how the control surfaces respond to input. The response to aileron or elevator input can be increased by setting this parameter to a positive or negative value. A common usage is to enter a positive value to increase the aileron response of the elevons of a flying wing. The default value of zero will leave the aileron-input response equal to the elevator-input response.

Range	Units
-1000 to 1000	decipercent

DSPOILR_RUD_RATE: Differential spoilers rudder rate

Sets the amount of deflection that the rudder output will apply to the differential spoilers, as a percentage. The default value of 100 results in full rudder applying full deflection. A value of 0 will result in the differential spoilers exactly following the elevons (no rudder effect).

Range	Units
-100 to 100	percent

LOG_BITMASK: Log bitmask

Units
meters

CRUISE_ALT_FLOOR: Minimum altitude for FBWB and CRUISE mode

This is the minimum altitude in meters (above home) that FBWB and CRUISE modes will allow. If you attempt to descend below this altitude then the plane will level off. It will also force a climb to this altitude if below in these modes. A value of zero means no limit.

Units
meters

FLAP_1_PERCNT: Flap 1 percentage

OVERRIDE_CHAN: IO override channel

Note: This parameter is for advanced users

If set to a non-zero value then this is an RC input channel number to use for giving IO manual control in case the main FMU microcontroller on a board with a IO co-processor fails. When this RC input channel goes above 1750 the FMU microcontroller will no longer be involved in controlling the servos and instead the IO microcontroller will directly control the servos. Note that IO manual control will be automatically activated if the FMU crashes for any reason. This parameter allows you to test for correct manual behaviour without actually crashing the FMU. This parameter is can be set to a non-zero value either for ground testing purposes or for giving the effect of an external override control board. Note that you may set OVERRIDE_CHAN to the same channel as FLTMODE_CH to get IO based override when in flight mode 6. Note that when override is triggered due to a FMU crash the 6 auxiliary output channels on the FMU will no longer be updated, so all the flight controls you need must be assigned to the first 8 channels on boards with an IOMCU.

Increment	Range
1	0 to 16

RTL_AUTOLAND: RTL auto land

Automatically begin landing sequence after arriving at RTL location. This requires the addition of a DO_LAND_START mission item, which acts as a marker for the start of a landing sequence. The closest landing sequence will be chosen to the current location For a value of 1 a rally point will be used instead of HOME if in range (see rally point documentation).If this is set to 0 and there is a DO_LAND_START or DO_RETURN_PATH_START mission item then you will get an arming check failure. You can set to a value of 3 to avoid the arming check failure and use the DO_LAND_START for go-around (see wiki for aborting autolandings) without it changing RTL behaviour.

Values
Value Meaning 0 Disable 1 Fly HOME then land via DO_LAND_START mission item 2 Go directly to landing sequence via DO_LAND_START mission item 3 OnlyForGoAround 4 Go directly to landing sequence via DO_RETURN_PATH_START mission item

CRASH_ACC_THRESH: Crash Deceleration Threshold

This value should be much higher than normal negative x-axis forces during normal flight, check flight log files to determine the average IMU.x values for your aircraft and motor type. Higher value means less sensitive (triggers on higher impact). For electric planes that don't vibrate much during fight a value of 25 is good (that's about 2.5G). For petrol/nitro planes you'll want a higher value. Set to 0 to disable the collision detector.

AFS_AMSL_LIMIT: AMSL limit

Note: This parameter is for advanced users

This sets the AMSL (above mean sea level) altitude limit. If the pressure altitude determined by QNH exceeds this limit then flight termination will be forced. Note that this limit is in meters, whereas pressure altitude limits are often quoted in feet. A value of zero disables the pressure altitude limit.

If this parameter is set to 1, then an RC loss will only cause the plane to terminate in manual control modes. If it is 0, then the plane will terminate in any flight mode.

AFS_DUAL_LOSS: Enable dual loss terminate due to failure of both GCS and GPS simultaneously

Note: This parameter is for advanced users

This enables the dual loss termination part of the AFS system. If this parameter is 1 and both GPS and the ground control station fail simultaneously, this will be considered a "dual loss" and cause termination.

AFS_RC_FAIL_TIME: RC failure time

Note: This parameter is for advanced users

This is the time in seconds in manual mode that failsafe termination will activate if RC input is lost. For the OBC rules this should be (1.5). Use 0 to disable.

AHRS_ Parameters

AHRS_GPS_GAIN: AHRS GPS gain

Note: This parameter is for advanced users

This controls how much to use the GPS to correct the attitude. This should never be set to zero for a plane as it would result in the plane losing control in turns. For a plane please use the default value of 1.0.

Increment	Range
0.01	0.0 to 1.0

AHRS_GPS_USE: AHRS use GPS for DCM navigation and position-down

Note: This parameter is for advanced users

This controls whether to use dead-reckoning or GPS based navigation. If set to 0 then the GPS won't be used for navigation, and only dead reckoning will be used. A value of zero should never be used for normal flight. Currently this affects only the DCM-based AHRS: the EKF uses GPS according to its own parameters. A value of 2 means to use GPS for height as well as position - both in DCM estimation and when determining altitude-above-home.

Values

Note: This parameter is for advanced users

This controls how fast the accelerometers correct the attitude

Increment	Range

AHRS_WIND_MAX: Maximum wind

Note: This parameter is for advanced users

This sets the maximum allowable difference between ground speed and airspeed. A value of zero means to use the airspeed as is. This allows the plane to cope with a failing airspeed sensor by clipping it to groundspeed plus/minus this limit. See ARSPD_OPTIONS and ARSPD_WIND_MAX to disable airspeed sensors.

AHRS_ORIENTATION: Board Orientation

Note: This parameter is for advanced users

Overall board orientation relative to the standard orientation for the board type. This rotates the IMU and compass readings to allow the board to be oriented in your vehicle at any 90 or 45 degree angle. The label for each option is specified in the order of rotations for that orientation. This option takes affect on next boot. After changing you will need to re-level your vehicle. Firmware versions 4.2 and prior can use a CUSTOM (100) rotation to set the AHRS_CUSTOM_ROLL/PIT/YAW angles for AHRS orientation. Later versions provide two general custom rotations which can be used, Custom 1 and Custom 2, with CUST_ROT1_ROLL/PIT/YAW or CUST_ROT2_ROLL/PIT/YAW angles.

Note: This parameter is for advanced users

Must have value "1" if crashdump data is present on the system, or a prearm failure will be raised. Do not set this parameter unless the risks of doing so are fully understood. The presence of a crash dump means that the firmware currently installed has suffered a critical software failure which resulted in the autopilot immediately rebooting. The crashdump file gives diagnostic information which can help in finding the issue, please contact the ArduPIlot support team. If this crashdump data is present, the vehicle is likely unsafe to fly. Check the ArduPilot documentation for more details.

ARSPD Parameters

ARSPD_ENABLE: Airspeed Enable

Values
Value Meaning 0 Disable 1 Enable

ARSPD_TUBE_ORDER: Control pitot tube order

Note: This parameter is for advanced users

This parameter allows you to control whether the order in which the tubes are attached to your pitot tube matters. If you set this to 0 then the first (often the top) connector on the sensor needs to be the stagnation pressure (the pressure at the tip of the pitot tube). If set to 1 then the second (often the bottom) connector needs to be the stagnation pressure. If set to 2 (the default) then the airspeed driver will accept either order. The reason you may wish to specify the order is it will allow your airspeed sensor to detect if the aircraft is receiving excessive pressure on the static port compared to the stagnation port such as during a stall, which would otherwise be seen as a positive airspeed.

ARSPD_WIND_GATE: Re-enable Consistency Check Gate Size

Note: This parameter is for advanced users

Number of standard deviations applied to the re-enable EKF consistency check that is used when ARSPD_OPTIONS bit position 3 is set. Larger values will make the re-enabling of the airspeed sensor faster, but increase the likelihood of re-enabling a degraded sensor. The value can be tuned by using the ARSP.TR log message by setting ARSPD_WIND_GATE to a value that is higher than the value for ARSP.TR observed with a healthy airspeed sensor. Occasional transients in ARSP.TR above the value set by ARSPD_WIND_GATE can be tolerated provided they are less than 5 seconds in duration and less than 10% duty cycle.

Range
0.0 to 10.0

ARSPD_OFF_PCNT: Maximum offset cal speed error

COMPASS_ORIENT: Compass orientation

Note: This parameter is for advanced users

The orientation of the first external compass relative to the vehicle frame. This value will be ignored unless this compass is set as an external compass. When set correctly in the northern hemisphere, pointing the nose and right side down should increase the MagX and MagY values respectively. Rolling the vehicle upside down should decrease the MagZ value. For southern hemisphere, switch increase and decrease. NOTE: For internal compasses, AHRS_ORIENT is used. The label for each option is specified in the order of rotations for that orientation. Firmware versions 4.2 and prior can use a CUSTOM (100) rotation to set the COMPASS_CUS_ROLL/PIT/YAW angles for Compass orientation. Later versions provide two general custom rotations which can be used, Custom 1 and Custom 2, with CUST_1_ROLL/PIT/YAW or CUST_2_ROLL/PIT/YAW angles.

If EK3_GLITCH_RAD has been set to 0 the horizontal position innovations will be clipped instead of rejected if they exceed the gate size so a smaller value of EK3_POS_I_GATE not exceeding 300 is recommended to limit the effect of GPS transient errors.

Increment	Range
25	100 to 1000

EK3_GLITCH_RAD: GPS glitch radius gate size (m)

Note: This parameter is for advanced users

This controls the maximum radial uncertainty in position between the value predicted by the filter and the value measured by the GPS before the filter position and velocity states are reset to the GPS. Making this value larger allows the filter to ignore larger GPS glitches but also means that non-GPS errors such as IMU and compass can create a larger error in position before the filter is forced back to the GPS position. If EK3_GLITCH_RAD set to 0 the GPS innovations will be clipped instead of rejected if they exceed the gate size set by EK3_VEL_I_GATE and EK3_POS_I_GATE which can be useful if poor quality sensor data is causing GPS rejection and loss of navigation but does make the EKF more susceptible to GPS glitches. If setting EK3_GLITCH_RAD to 0 it is recommended to reduce EK3_VEL_I_GATE and EK3_POS_I_GATE to 300.

Increment	Range	Units

EK3_ALT_M_NSE: Altitude measurement noise (m)

Note: This parameter is for advanced users

This is the RMS value of noise in the altitude measurement. Increasing it reduces the weighting of the baro measurement and will make the filter respond more slowly to baro measurement errors, but will make it more sensitive to GPS and accelerometer errors. A larger value for EK3_ALT_M_NSE may be required when operating with EK3_SRCx_POSZ = 0. This parameter also sets the noise for the 'synthetic' zero height measurement that is used when EK3_SRCx_POSZ = 0.

Increment	Range	Units
0.1	0.1 to 100.0	meters

EK3_HGT_I_GATE: Height measurement gate size

Note: This parameter is for advanced users

This sets the percentage number of standard deviations applied to the height measurement innovation consistency check. Decreasing it makes it more likely that good measurements will be rejected. Increasing it makes it more likely that bad measurements will be accepted. If EK3_GLITCH_RAD set to 0 the vertical position innovations will be clipped instead of rejected if they exceed the gate size and a smaller value of EK3_HGT_I_GATE not exceeding 300 is recommended to limit the effect of height sensor transient errors.

Increment	Range

EK3_MAG_CAL: Magnetometer default fusion mode

Note: This parameter is for advanced users

Note: Reboot required after change

This determines when the filter will use the 3-axis magnetometer fusion model that estimates both earth and body fixed magnetic field states and when it will use a simpler magnetic heading fusion model that does not use magnetic field states. The 3-axis magnetometer fusion is only suitable for use when the external magnetic field environment is stable. EK3_MAG_CAL = 0 uses heading fusion on ground, 3-axis fusion in-flight, and is the default setting for Plane users. EK3_MAG_CAL = 1 uses 3-axis fusion only when manoeuvring. EK3_MAG_CAL = 2 uses heading fusion at all times, is recommended if the external magnetic field is varying and is the default for rovers. EK3_MAG_CAL = 3 uses heading fusion on the ground and 3-axis fusion after the first in-air field and yaw reset has completed, and is the default for copters. EK3_MAG_CAL = 4 uses 3-axis fusion at all times. EK3_MAG_CAL = 5 uses an external yaw sensor with simple heading fusion. NOTE : Use of simple heading magnetometer fusion makes vehicle compass calibration and alignment errors harder for the EKF to detect which reduces the sensitivity of the Copter EKF failsafe algorithm. NOTE: The fusion mode can be forced to 2 for specific EKF cores using the EK3_MAG_MASK parameter. EK3_MAG_CAL = 6 uses an external yaw sensor with fallback to compass when the external sensor is not available if we are flying. NOTE: The fusion mode can be forced to 2 for specific EKF cores using the EK3_MAG_MASK parameter. NOTE: limited operation without a magnetometer or any other yaw sensor is possible by setting all COMPASS_USE, COMPASS_USE2, COMPASS_USE3, etc parameters to 0 and setting COMPASS_ENABLE to 0. If this is done, the EK3_GSF_RUN and EK3_GSF_USE masks must be set to the same as EK3_IMU_MASK. A yaw angle derived from IMU and GPS velocity data using a Gaussian Sum Filter (GSF) will then be used to align the yaw when flight commences and there is sufficient movement.

EK3_NOAID_M_NSE: Non-GPS operation position uncertainty (m)

Note: This parameter is for advanced users

This sets the amount of position variation that the EKF allows for when operating without external measurements (eg GPS or optical flow). Increasing this parameter makes the EKF attitude estimate less sensitive to vehicle manoeuvres but more sensitive to IMU errors.

Range	Units
0.5 to 50.0	meters

EK3_BETA_MASK: Bitmask controlling sidelip angle fusion

Note: This parameter is for advanced users

Note: Reboot required after change

1 byte bitmap controlling use of sideslip angle fusion for estimation of non wind states during operation of 'fly forward' vehicle types such as fixed wing planes. By assuming that the angle of sideslip is small, the wind velocity state estimates are corrected whenever the EKF is not dead reckoning (e.g. has an independent velocity or position sensor such as GPS). This behaviour is on by default and cannot be disabled. When the EKF is dead reckoning, the wind states are used as a reference, enabling use of the small angle of sideslip assumption to correct non wind velocity states (eg attitude, velocity, position, etc) and improve navigation accuracy. This behaviour is on by default and cannot be disabled. The behaviour controlled by this parameter is the use of the small angle of sideslip assumption to correct non wind velocity states when the EKF is NOT dead reckoning. This is primarily of benefit to reduce the buildup of yaw angle errors during straight and level flight without a yaw sensor (e.g. magnetometer or dual antenna GPS yaw) provided aerobatic flight maneuvers with large sideslip angles are not performed. The 'always' option might be used where the yaw sensor is intentionally not fitted or disabled. The 'WhenNoYawSensor' option might be used if a yaw sensor is fitted, but protection against in-flight failure and continual rejection by the EKF is desired. For vehicles operated within visual range of the operator performing frequent turning maneuvers, setting this parameter is unnecessary.

EK3_OGN_HGT_MASK: Bitmask control of EKF reference height correction

Note: This parameter is for advanced users

Note: Reboot required after change

When a height sensor other than GPS is used as the primary height source by the EKF, the position of the zero height datum is defined by that sensor and its frame of reference. If a GPS height measurement is also available, then the height of the WGS-84 height datum used by the EKF can be corrected so that the height returned by the getLLH() function is compensated for primary height sensor drift and change in datum over time. The first two bit positions control when the height datum will be corrected. Correction is performed using a Bayes filter and only operates when GPS quality permits. The third bit position controls where the corrections to the GPS reference datum are applied. Corrections can be applied to the local vertical position or to the reported EKF origin height (default).

EK3_DRAG_BCOEF_X: Ballistic coefficient for X axis drag

Note: This parameter is for advanced users

Increment	Range	Units
0.1	0.1 to 2.0	meters per square second

EK3_DRAG_MCOEF: Momentum coefficient for propeller drag

Note: This parameter is for advanced users

This parameter is used to predict the drag produced by the rotors when flying a multi-copter, enabling estimation of wind drift. The drag produced by this effect scales with speed not speed squared and is produced because some of the air velocity normal to the rotors axis of rotation is lost when passing through the rotor disc which changes the momentum of the airflow causing drag. For unducted rotors the effect is roughly proportional to the area of the propeller blades when viewed side on and changes with different propellers. It is higher for ducted rotors. For example if flying at 15 m/s at sea level conditions produces a rotor induced drag acceleration of 1.5 m/s/s, then EK3_DRAG_MCOEF would be set to 0.1 = (1.5/15.0). Set EK3_MCOEF to a positive value to enable wind estimation using this drag effect. To account for the drag produced by the body which scales with speed squared, see documentation for the EK3_DRAG_BCOEF_X and EK3_DRAG_BCOEF_Y parameters.

Bit 1 (Manual lane switching): DANGEROUS – If enabled, this disables automatic lane switching. If the active lane becomes unhealthy, no automatic switching will occur.

Setting this to 1 will always target the highest energy peak. Setting this to 2 will target the highest energy peak that is lower in frequency than the highest energy peak. Setting this to 3 will target the highest energy peak that is higher in frequency than the highest energy peak. Setting this to 4 will target the highest energy peak on the roll axis only and only the roll frequency will be used (some vehicles have a much more pronounced peak on roll). Setting this to 5 will target the highest energy peak on the pitch axis only and only the pitch frequency will be used (some vehicles have a much more pronounced peak on roll).

INS_HNTC2_REF: Harmonic Notch Filter reference value

Note: This parameter is for advanced users

Note: Reboot required after change

A reference value of zero disables dynamic updates on the Harmonic Notch Filter and a positive value enables dynamic updates on the Harmonic Notch Filter. For throttle-based scaling, this parameter is the reference value associated with the specified frequency to facilitate frequency scaling of the Harmonic Notch Filter. For RPM and ESC telemetry based tracking, this parameter is set to 1 to enable the Harmonic Notch Filter using the RPM sensor or ESC telemetry set to measure rotor speed. The sensor data is converted to Hz automatically for use in the Harmonic Notch Filter. This reference value may also be used to scale the sensor data, if required. For example, rpm sensor data is required to measure heli motor RPM. Therefore the reference value can be used to scale the RPM sensor to the rotor RPM.

Multi-Source attaches a harmonic notch to each detected noise frequency instead of simply being multiples of the base frequency, in the case of FFT it will attach notches to each of three detected noise peaks, in the case of ESC it will attach notches to each of four motor RPM values. Loop rate update changes the notch center frequency at the scheduler loop rate rather than at the default of 200Hz. If both double and triple notches are specified only double notches will take effect.

INS_HNTC2_FM_RAT: Throttle notch min frequency ratio

Note: This parameter is for advanced users

The minimum ratio below the configured frequency to take throttle based notch filters when flying at a throttle level below the reference throttle. Note that lower frequency notch filters will have more phase lag. If you want throttle based notch filtering to be effective at a throttle up to 30% below the configured notch frequency then set this parameter to 0.7. The default of 1.0 means the notch will not go below the frequency in the FREQ parameter.

Range

Values
Value Meaning 0 Disabled 1 Enabled

INS_HNTC3_FREQ: Harmonic Notch Filter base frequency

Note: This parameter is for advanced users

Harmonic Notch Filter base center frequency in Hz. This is the center frequency for static notches, the center frequency for Throttle based notches at the reference thrust value, and the minimum limit of center frequency variation for all other notch types. This should always be set lower than half the backend gyro rate (which is typically 1Khz).

Range	Units
10 to 495	hertz

INS_HNTC3_BW: Harmonic Notch Filter bandwidth

Note: This parameter is for advanced users

Harmonic Notch Filter bandwidth in Hz. This is typically set to half the base frequency. The ratio of base frequency to bandwidth determines the notch quality factor and is fixed across harmonics.

Range	Units
5 to 250	hertz

INS_HNTC3_ATT: Harmonic Notch Filter attenuation

Note: This parameter is for advanced users

Harmonic Notch Filter attenuation in dB. Values greater than 40dB will typically produce a hard notch rather than a modest attenuation of motor noise.

INS_HNTC3_REF: Harmonic Notch Filter reference value

Note: This parameter is for advanced users

Note: Reboot required after change

A reference value of zero disables dynamic updates on the Harmonic Notch Filter and a positive value enables dynamic updates on the Harmonic Notch Filter. For throttle-based scaling, this parameter is the reference value associated with the specified frequency to facilitate frequency scaling of the Harmonic Notch Filter. For RPM and ESC telemetry based tracking, this parameter is set to 1 to enable the Harmonic Notch Filter using the RPM sensor or ESC telemetry set to measure rotor speed. The sensor data is converted to Hz automatically for use in the Harmonic Notch Filter. This reference value may also be used to scale the sensor data, if required. For example, rpm sensor data is required to measure heli motor RPM. Therefore the reference value can be used to scale the RPM sensor to the rotor RPM.

KDE_ Parameters

KDE_NPOLE: Number of motor poles

Sets the number of motor poles to calculate the correct RPM value

LAND_ Parameters

LAND_SLOPE_RCALC: Landing slope re-calc threshold

Note: This parameter is for advanced users

This parameter is used when using a rangefinder during landing for altitude correction from baro drift (RNGFND_LANDING=1) and the altitude correction indicates your altitude is lower than the intended slope path. This value is the threshold of the correction to re-calculate the landing approach slope. Set to zero to keep the original slope all the way down and any detected baro drift will be corrected by pitching/throttling up to snap back to resume the original slope path. Otherwise, when a rangefinder altitude correction exceeds this threshold it will trigger a slope re-calculate to give a shallower slope. This also smoothes out the approach when flying over objects such as trees. Recommend a value of 2m.

Normally it would pitch down steeply but that can result in a crash with high airspeed so this allows remembering the baro offset and self-abort the landing and come around for another landing with the correct baro offset applied for a perfect slope. An auto-abort go-around will only happen once, next attempt will not auto-abort again. This operation happens entirely automatically in AUTO mode. This value is the delta degrees threshold to trigger the go-around compared to the original slope. Example: if set to 5 deg and the mission planned slope is 15 deg then if the new slope is 21 then it will go-around. Set to 0 to disable. Requires LAND_SLOPE_RCALC > 0.

Increment	Range	Units
0.1	0 to 90	degrees

LAND_PITCH_DEG: Landing Pitch

Note: This parameter is for advanced users

Used in autoland to give the minimum pitch in the final stage of landing (after the flare). This parameter can be used to ensure that the final landing attitude is appropriate for the type of undercarriage on the aircraft. Note that it is a minimum pitch only - the landing code will control pitch above this value to try to achieve the configured landing sink rate.

Increment	Range	Units
10	-20 to 20	degrees

LAND_FLARE_ALT: Landing flare altitude

Note: This parameter is for advanced users

Altitude in autoland at which to lock heading and flare to the LAND_PITCH_DEG pitch. Note that this option is secondary to LAND_FLARE_SEC. For a good landing it preferable that the flare is triggered by LAND_FLARE_SEC.

Increment	Range	Units
0.1	0 to 30	meters

LAND_FLARE_SEC: Landing flare time

Note: This parameter is for advanced users

Vertical time before landing point at which to lock heading and flare with the motor stopped. This is vertical time, and is calculated based solely on the current height above the ground and the current descent rate. Set to 0 if you only wish to flare based on altitude (see LAND_FLARE_ALT).

Increment	Range	Units
0.1	0 to 10	seconds

LAND_PF_ALT: Landing pre-flare altitude

Note: This parameter is for advanced users

Increment	Range	Units
0.1	0 to 30	meters

LAND_PF_SEC: Landing pre-flare time

Note: This parameter is for advanced users

Vertical time to ground to trigger pre-flare flight stage where LAND_PF_ARSPD controls airspeed. This pre-flare flight stage trigger works just like LAND_FLARE_SEC but earlier. Disabled when LAND_PF_ARSPD is 0.

Increment	Range	Units
0.1	0 to 10	seconds

LAND_PF_ARSPD: Landing pre-flare airspeed

Values below 50 are not recommended as it may cause a stall when airspeed is low and you can not throttle up fast enough.

Increment	Range	Units
1	0 to 127	percent

LAND_FLARE_AIM: Flare aim point adjustment percentage.

Note: This parameter is for advanced users

This parameter controls how much the aim point is moved to allow for the time spent in the flare manoeuvre. When set to 100% the aim point is adjusted on the assumption that the flare sink rate controller instantly achieves the sink rate set by TECS_LAND_SINK. when set to 0%, no aim point adjustment is made. If the plane consistently touches down short of the aim point reduce the parameter and vice verse.

Increment	Range	Units
1	0 to 100	percent

LAND_WIND_COMP: Headwind Compensation when Landing

Note: This parameter is for advanced users

Bitmap of what Logger backend types to enable. Block-based logging is available on SITL and boards with dataflash chips. Multiple backends can be selected.

Bitmask
Bit Meaning 0 File 1 MAVLink 2 Block

LOG_FILE_BUFSIZE: Logging File and Block Backend buffer size max (in kibibytes)

The File and Block backends use a buffer to store data before writing to the block device. Raising this value may reduce "gaps" in your SD card logging but increases memory usage. This buffer size may be reduced to free up available memory

Range	Units
4 to 200	kibibytes

LOG_DISARMED: Enable logging while disarmed

If LOG_DISARMED is set to 1 then logging will be enabled at all times including when disarmed. Logging before arming can make for very large logfiles but can help a lot when tracking down startup issues and is necessary if logging of EKF replay data is selected via the LOG_REPLAY parameter. If LOG_DISARMED is set to 2, then logging will be enabled when disarmed, but not if a USB connection is detected. This can be used to prevent unwanted data logs being generated when the vehicle is connected via USB for log downloading or parameter changes. If LOG_DISARMED is set to 3 then logging will happen while disarmed, but if the vehicle never arms then the logs using the filesystem backend will be discarded on the next boot.

Values
Value Meaning 0 Disabled 1 Enabled 2 Disabled on USB connection 3 Discard log on reboot if never armed

LOG_REPLAY: Enable logging of information needed for Replay

It is suggested that you also raise LOG_FILE_BUFSIZE to give more buffer space for logging and use a high quality microSD card to ensure no sensor data is lost.

Values
Value Meaning 0 Disabled 1 Enabled

LOG_FILE_DSRMROT: Stop logging to current file on disarm

NAVL1_ Parameters

NAVL1_PERIOD: L1 control period

Period in seconds of L1 tracking loop. This parameter is the primary control for aggressiveness of turns in auto mode. This needs to be larger for less responsive airframes. The default is quite conservative, but for most RC aircraft will lead to reasonable flight. For smaller more agile aircraft a value closer to 15 is appropriate, or even as low as 10 for some very agile aircraft. When tuning, change this value in small increments, as a value that is much too small (say 5 or 10 below the right value) can lead to very radical turns, and a risk of stalling.

Increment	Range	Units
1	1 to 60	seconds

NAVL1_DAMPING: L1 control damping ratio

Note: This parameter is for advanced users

Damping ratio for L1 control. Increase this in increments of 0.05 if you are getting overshoot in path tracking. You should not need a value below 0.7 or above 0.85.

Increment	Range
0.05	0.6 to 1.0

NAVL1_XTRACK_I: L1 control crosstrack integrator gain

Note: This parameter is for advanced users

Crosstrack error integrator gain. This gain is applied to the crosstrack error to ensure it converges to zero. Set to zero to disable. Smaller values converge slower, higher values will cause crosstrack error oscillation.

Increment	Range
0.01	0 to 0.1

NAVL1_LIM_BANK: Loiter Radius Bank Angle Limit

Note: This parameter is for advanced users

The sealevel bank angle limit for a continuous loiter. (Used to calculate airframe loading limits at higher altitudes). Setting to 0, will instead just scale the loiter radius directly

Range	Units
0 to 89	degrees

This controls how much quicktune is allowed to lower gains from the original gains. If the vehicle already has a reasonable tune and is not oscillating then you can set this to zero to prevent gain reductions. The default of 20% is reasonable for most vehicles.

This is the speed below which the quad motors will provide stability and lift assistance in fixed wing modes. The default value of 0 disables assistance but will generate a pre-arm failure to encourage users to set this parameter to -1, or a positive, non-zero value. If this is set to -1 then all Q_ASSIST features are disabled except during transitions. A high non-zero,positive value will lead to more false positives which can waste battery. A lower value will result in less false positive, but will result in assistance taking longer to trigger. If unsure then set to 3 m/s below the minimum airspeed you will fly at. If you don't have an airspeed sensor then use 5 m/s below the minimum airspeed you fly at.

This Q_VFD_GAIN parameter controls use of the forward motor in VTOL modes that use the velocity controller. Set to 0 to disable this function. A value of 0.05 is a good place to start if you want to use the forward motor for position control. No forward motor will be used in QSTABILIZE or QHOVER modes.

Increment	Range	Units
1	1 to 200	meters

Q_FWD_THR_GAIN: Q mode fwd throttle gain

This parameter sets the gain from forward accel/tilt to forward throttle in certain Q modes. The Q modes this feature operates in is controlled by the Q_FWD_THR_USE parameter. Vehicles using separate forward thrust motors, eg quadplanes, should set this parameter to (all up weight) / (maximum combined thrust of forward motors) with a value of 2 being typical. Vehicles that tilt lifting rotors to provide forward thrust should set this parameter to (all up weight) / (weight lifted by tilting rotors) which for most aircraft can be approximated as (total number of lifting rotors) / (number of lifting rotors that tilt). When using this method of forward throttle control, the forward tilt angle limit is controlled by the Q_FWD_PIT_LIM parameter.

Increment	Range
0.1	0.0 to 5.0

Q_FWD_PIT_LIM: Q mode forward pitch limit

When forward throttle is being controlled by the Q_FWD_THR_GAIN parameter in Q modes, the vehicle forward (nose down) pitch rotation will be limited to the value specified by this parameter and the any additional forward acceleration required will be produced by use of the forward thrust motor(s) or tilting of moveable rotors. Larger values allow the vehicle to pitch more nose down. Set initially to the amount of nose down pitch required to remove wing lift.

Increment	Range	Units
0.1	0.0 to 5.0	degrees

Q_FWD_THR_USE: Q mode forward throttle use

This parameter determines when the feature that uses forward throttle instead of forward tilt is used. The amount of forward throttle is controlled by the Q_FWD_THR_GAIN parameter. The maximum amount of forward pitch allowed is controlled by the Q_FWD_PIT_LIM parameter. Q_FWD_THR_USE = 0 disables the feature. Q_FWD_THR_USE = 1 enables the feature in all position controlled modes such as QLOITER, QLAND, QRTL and VTOL TAKEOFF. Q_FWD_THR_USE = 2 enables the feature in all Q modes except QAUTOTUNE and QACRO. When enabling the feature, the legacy method of controlling forward throttle use via velocity controller error should be disabled by setting Q_VFWD_GAIN to 0. Do not use this feature with tailsitters.

Values
Value Meaning 0 Off 1 On in all position controlled Q modes 2 On in all Q modes except QAUTOTUNE and QACRO

Q_BCK_PIT_LIM: Q mode rearward pitch limit

This sets the maximum number of degrees of back or pitch up in Q modes when the airspeed is at AIRSPEED_MIN, and is used to prevent excessive sutructural loads when pitching up decelerate. If airspeed is above or below AIRSPEED_MIN, the pitch up/back will be adjusted according to the formula pitch_limit = Q_BCK_PIT_LIM * (AIRSPEED_MIN / IAS)^2. The backwards/up pitch limit controlled by this parameter is in addition to limiting applied by PTCH_LIM_MAX_DEG and Q_ANGLE_MAX. The BCK_PIT_LIM limit is only applied when Q_FWD_THR_USE is set to 1 or 2 and the vehicle is flying in a mode that uses forward throttle instead of forward tilt to generate forward speed. Set to a non positive value 0 to deactivate this limit.

Increment	Range	Units

RLL Parameters

RLL2SRV_TCONST: Roll Time Constant

Note: This parameter is for advanced users

Time constant in seconds from demanded to achieved roll angle. Most models respond well to 0.5. May be reduced for faster responses, but setting lower than a model can achieve will not help.

Increment	Range	Units
0.1	0.4 to 1.0	seconds

RLL2SRV_RMAX: Maximum Roll Rate

Note: This parameter is for advanced users

This sets the maximum roll rate that the attitude controller will demand (degrees/sec) in angle stabilized modes. Setting it to zero disables this limit.

Increment	Range	Units
1	0 to 50	hertz

RLL_RATE_SMAX: Roll slew rate limit

Note: This parameter is for advanced users

Sets an upper limit on the slew rate produced by the combined P and D gains. If the amplitude of the control action produced by the rate feedback exceeds this value, then the D+P gain is reduced to respect the limit. This limits the amplitude of high frequency oscillations caused by an excessive gain. The limit should be set to no more than 25% of the actuators maximum slew rate to allow for load effects. Note: The gain will not be reduced to less than 10% of the nominal value. A value of zero will disable this feature.

SERIAL_PASSTIMO: Serial passthru timeout

Note: This parameter is for advanced users

This sets a timeout for serial pass-through in seconds. When the pass-through is enabled by setting the SERIAL_PASS1 and SERIAL_PASS2 parameters then it remains in effect until no data comes from the first port for SERIAL_PASSTIMO seconds. This allows the port to revent to its normal usage (such as MAVLink connection to a GCS) when it is no longer needed. A value of 0 means no timeout. A value of -1 means no timeout and the SERIAL_PASS2 parameter is not reset on reboot.

SERVO_VOLZ_RANGE: Range of travel

Range to map between 1000 and 2000 PWM. Default value of 200 gives full +-100 deg range of extended position command. This results in 0.2 deg movement per US change in PWM. If the full range is not needed it can be reduced to increase resolution. 40 deg range gives 0.04 deg movement per US change in PWM, this is higher resolution than possible with the VOLZ protocol so further reduction in range will not improve resolution. Reduced range does allow PWMs outside the 1000 to 2000 range, with 40 deg range 750 PWM results in a angle of -30 deg, 2250 would be +30 deg. This is still limited by the 200 deg maximum range of the actuator.

STEER2SRV_ Parameters

STEER2SRV_TCONST: Steering Time Constant

Note: This parameter is for advanced users

This controls the time constant in seconds from demanded to achieved steering angle. A value of 0.75 is a good default and will work with nearly all rovers. Ground steering in aircraft needs a bit smaller time constant, and a value of 0.5 is recommended for best ground handling in fixed wing aircraft. A value of 0.75 means that the controller will try to correct any deviation between the desired and actual steering angle in 0.75 seconds. Advanced users may want to reduce this time to obtain a faster response but there is no point setting a time less than the vehicle can achieve.

Increment	Range	Units
0.1	0.4 to 1.0	seconds

STEER2SRV_P: Steering turning gain

The proportional gain for steering. This should be approximately equal to the diameter of the turning circle of the vehicle at low speed and maximum steering angle

Increment	Range
0.1	0.1 to 10.0

STEER2SRV_I: Integrator Gain

This is the gain from the integral of steering angle. Increasing this gain causes the controller to trim out steady offsets due to an out of trim vehicle.

Increment	Range
0.05	0 to 1.0

STEER2SRV_D: Damping Gain

This adjusts the damping of the steering control loop. This gain helps to reduce steering jitter with vibration. It should be increased in 0.01 increments as too high a value can lead to a high frequency steering oscillation that could overstress the vehicle.

Increment	Range
0.01	0 to 0.1

STEER2SRV_IMAX: Integrator limit

Note: This parameter is for advanced users

This limits the number of degrees of steering in centi-degrees over which the integrator will operate. At the default setting of 1500 centi-degrees, the integrator will be limited to +- 15 degrees of servo travel. The maximum servo deflection is +- 45 centi-degrees, so the default value represents a 1/3rd of the total control throw which is adequate unless the vehicle is severely out of trim.

Increment	Range	Units
10	0 to 4500	centidegrees

STEER2SRV_MINSPD: Minimum speed

This is the minimum assumed ground speed in meters/second for steering. Having a minimum speed prevents oscillations when the vehicle first starts moving. The vehicle can still drive slower than this limit, but the steering calculations will be done based on this minimum speed.

Increment	Range	Units
0.1	0 to 5	meters per second

STEER2SRV_FF: Steering feed forward

The feed forward gain for steering this is the ratio of the achieved turn rate to applied steering. A value of 1 means that the vehicle would yaw at a rate of 45 degrees per second with full steering deflection at 1m/s ground speed.

Increment	Range
0.1	0.0 to 10.0

STEER2SRV_DRTSPD: Derating speed

Note: This parameter is for advanced users

STEER2SRV_DRTFCT: Derating factor

Note: This parameter is for advanced users

Degrees of steering wheel to derate at each additional m/s of speed above "Derating speed". Should be set so that at higher speeds the plane does not roll to the wing in turns.

Increment	Range	Units
10	0 to 4500	centidegrees

Note: This parameter is for advanced users

Gain from bank angle to throttle to compensate for loss of airspeed from drag in turns. Set to approximately 10x the sink rate in m/s caused by a 45-degree turn. High efficiency models may need less while less efficient aircraft may need more. Should be tuned in an automatic mission with waypoints and turns greater than 90 degrees. Tune with PTCH2SRV_RLL and KFF_RDDRMIX to achieve constant airspeed, constant altitude turns.

Increment	Range
1.0	5.0 to 30.0

TECS_SPDWEIGHT: Weighting applied to speed control

Note: This parameter is for advanced users

Increment	Range
0.1	0.0 to 2.0

TECS_PTCH_DAMP: Controller pitch damping

Note: This parameter is for advanced users

Increment	Range
0.1	0.1 to 1.0

TECS_SINK_MAX: Maximum Descent Rate (metres/sec)

Maximum demanded descent rate. Do not set higher than the vertical speed the aircraft can maintain at THR_MIN, TECS_PITCH_MIN, and AIRSPEED_MAX.

Increment	Range
0.1	0.0 to 20.0

TECS_LAND_ARSPD: Airspeed during landing approach (m/s)

When performing an autonomous landing, this value is used as the goal airspeed during approach. Max airspeed allowed is Trim Airspeed or AIRSPEED_MAX as defined by LAND_OPTIONS bitmask. Note that this parameter is not useful if your platform does not have an airspeed sensor (use TECS_LAND_THR instead). If negative then this value is halfway between AIRSPEED_MIN and AIRSPEED_CRUISE speed for fixed wing autolandings.

Increment	Range
1	-1 to 127

TECS_LAND_THR: Cruise throttle during landing approach (percentage)

Use this parameter instead of LAND_ARSPD if your platform does not have an airspeed sensor. It is the cruise throttle during landing approach. If this value is negative then it is disabled and TECS_LAND_ARSPD is used instead.

Increment	Range
0.1	-1 to 100

TECS_LAND_SPDWGT: Weighting applied to speed control during landing.

Note: This parameter is for advanced users

Same as SPDWEIGHT parameter, with the exception that this parameter is applied during landing flight stages. A value closer to 2 will result in the plane ignoring height error during landing and our experience has been that the plane will therefore keep the nose up -- sometimes good for a glider landing (with the side effect that you will likely glide a ways past the landing point). A value closer to 0 results in the plane ignoring speed error -- use caution when lowering the value below 1 -- ignoring speed could result in a stall. Values between 0 and 2 are valid values for a fixed landing weight. When using -1 the weight will be scaled during the landing. At the start of the landing approach it starts with TECS_SPDWEIGHT and scales down to 0 by the time you reach the land point. Example: Halfway down the landing approach you'll effectively have a weight of TECS_SPDWEIGHT/2.

Increment	Range
0.1	-1.0 to 2.0

TECS_PITCH_MAX: Maximum pitch in auto flight

Note: This parameter is for advanced users

Overrides PTCH_LIM_MAX_DEG in automatic throttle modes to reduce climb rates. Uses PTCH_LIM_MAX_DEG if set to 0. For proper TECS tuning, set to the angle that the aircraft can climb at AIRSPEED_CRUISE and THR_MAX.

Increment	Range
1	0 to 45

TECS_PITCH_MIN: Minimum pitch in auto flight

Note: This parameter is for advanced users

Overrides PTCH_LIM_MIN_DEG in automatic throttle modes to reduce descent rates. Uses PTCH_LIM_MIN_DEG if set to 0. For proper TECS tuning, set to the angle that the aircraft can descend at without overspeeding.

Increment	Range
1	-45 to 0

Note: This parameter is for advanced users

The sink rate in meters/second for the final stage of landing.

Increment	Range
0.1	0.0 to 2.0

TECS_LAND_TCONST: Land controller time constant (sec)

Note: This parameter is for advanced users

This is the time constant of the TECS control algorithm when in final landing stage of flight. It should be smaller than TECS_TIME_CONST to allow for faster flare

Increment	Range
0.2	1.0 to 5.0

TECS_LAND_DAMP: Controller sink rate to pitch gain during flare

Note: This parameter is for advanced users

This is the sink rate gain for the pitch demand loop when in final landing stage of flight. It should be larger than TECS_PTCH_DAMP to allow for better sink rate control during flare.

Increment	Range
0.1	0.1 to 1.0

TECS_LAND_PMAX: Maximum pitch during final stage of landing

Note: This parameter is for advanced users

This limits the pitch used during the final stage of automatic landing. During the final landing stage most planes need to keep their pitch small to avoid stalling. A maximum of 10 degrees is usually good. A value of zero means to use the normal pitch limits.

Increment	Range
1	-5 to 40

TECS_APPR_SMAX: Sink rate max for landing approach stage

Note: This parameter is for advanced users

The sink rate max for the landing approach stage of landing. This will need to be large for steep landing approaches especially when using reverse thrust. If 0, then use TECS_SINK_MAX.

Increment	Range	Units
0.1	0.0 to 20.0	meters per second

TECS_LAND_SRC: Land sink rate change

Note: This parameter is for advanced users

When zero, the flare sink rate (TECS_LAND_SINK) is a fixed sink demand. With this enabled the flare sink rate will increase/decrease the flare sink demand as you get further beyond the LAND waypoint. Has no effect before the waypoint. This value is added to TECS_LAND_SINK proportional to distance traveled after wp. With an increasing sink rate you can still land in a given distance if you're traveling too fast and cruise passed the land point. A positive value will force the plane to land sooner proportional to distance passed land point. A negative number will tell the plane to slowly climb allowing for a pitched-up stall landing. Recommend 0.2 as initial value.

Increment	Range	Units
0.1	-2.0 to 2.0	meters per second per meter

TECS_LAND_TDAMP: Controller throttle damping when landing

Note: This parameter is for advanced users

Damping gain for the throttle demand loop during an auto-landing. Same as TECS_THR_DAMP but only in effect during an auto-land. Increase to add throttle activity to dampen oscillations in speed and height. When set to 0 landing throttle damping is controlled by TECS_THR_DAMP.

Increment	Range
0.1	0.1 to 1.0

Increment	Range
0.02	0.0 to 0.5

TECS_TKOFF_IGAIN: Controller integrator during takeoff

Note: This parameter is for advanced users

This is the integrator gain on the control loop during takeoff. Increase to increase the rate at which speed and height offsets are trimmed out.

Increment	Range
0.02	0.0 to 0.5

TECS_LAND_PDAMP: Pitch damping gain when landing

Note: This parameter is for advanced users

This is the damping gain for the pitch demand loop during landing. Increase to add damping to correct for oscillations in speed and height. If set to 0 then TECS_PTCH_DAMP will be used instead.

Increment	Range
0.1	0.1 to 1.0

TECS_SYNAIRSPEED: Enable the use of synthetic airspeed

Note: This parameter is for advanced users

This enables the use of synthetic airspeed in TECS for aircraft that don't have a real airspeed sensor. This is useful for development testing where the user is aware of the considerable limitations of the synthetic airspeed system, such as very poor estimates when a wind estimate is not accurate. Do not enable this option unless you fully understand the limitations of a synthetic airspeed estimate. This option has no effect if a healthy airspeed sensor is being used for airspeed measurements.

TECS_PTCH_FF_K: Gain for pitch feed-forward.

Note: This parameter is for advanced users

This parameter sets the gain between demanded airspeed and pitch. It has units of radians per metre per second and should generally be negative. A good starting value is -0.04 for gliders and -0.08 for draggy airframes. The default (0.0) disables this feed-forward.

Range
-5.0 to 0.0

TECS_THR_ERATE: Forward throttle external limit slew rate

Note: This parameter is for advanced users

Range	Units
0 to 100	percent per second

TECS_FLARE_HGT: Flare holdoff height

Note: This parameter is for advanced users

Range	Units
0 to 15	meters

TERRAIN_ Parameters

TERRAIN_ENABLE: Terrain data enable

Note: This parameter is for advanced users

enable terrain data. This enables the vehicle storing a database of terrain data on the SD card. The terrain data is requested from the ground station as needed, and stored for later use on the SD card. To be useful the ground station must support TERRAIN_REQUEST messages and have access to a terrain database, such as the SRTM database.

Values
Value Meaning 0 Disable 1 Enable

TERRAIN_SPACING: Terrain grid spacing

Note: This parameter is for advanced users

Distance between terrain grid points in meters. This controls the horizontal resolution of the terrain data that is stored on te SD card and requested from the ground station. If your GCS is using the ArduPilot SRTM database like Mission Planner or MAVProxy, then a resolution of 100 meters is appropriate. Grid spacings lower than 100 meters waste SD card space if the GCS cannot provide that resolution. The grid spacing also controls how much data is kept in memory during flight. A larger grid spacing will allow for a larger amount of data in memory. A grid spacing of 100 meters results in the vehicle keeping 12 grid squares in memory with each grid square having a size of 2.7 kilometers by 3.2 kilometers. Any additional grid squares are stored on the SD once they are fetched from the GCS and will be loaded as needed.

0.05 to 50000	meters

TERRAIN_OFS_MAX: Terrain reference offset maximum

Note: This parameter is for advanced users

The maximum adjustment of terrain altitude based on the assumption that the vehicle is on the ground when it is armed. When the vehicle is armed the location of the vehicle is recorded, and when terrain data is available for that location a height adjustment for terrain data is calculated that aligns the terrain height at that location with the altitude recorded at arming. This height adjustment is applied to all terrain data. This parameter clamps the amount of adjustment. A value of zero disables the use of terrain height adjustment.

Range	Units

TKOFF_ Parameters

TKOFF_ALT: Takeoff mode altitude

This is the target altitude for TAKEOFF mode

Increment	Range	Units
1	0 to 200	meters

TKOFF_LVL_ALT: Takeoff mode altitude level altitude

This is the altitude below which the wings are held level for TAKEOFF and AUTO modes. Below this altitude, roll demand is restricted to LEVEL_ROLL_LIMIT. Normal-flight roll restriction resumes above TKOFF_LVL_ALT*3 or TKOFF_ALT, whichever is lower. Roll limits are scaled while between TKOFF_LVL_ALT and those altitudes for a smooth transition.

Increment	Range	Units

This is the distance from the takeoff location where the plane will loiter. The loiter point will be in the direction of takeoff (the direction the plane is facing when the plane begins takeoff)

Increment	Range	Units
1	0 to 500	meters

TKOFF_GND_PITCH: Takeoff run pitch demand

Degrees of pitch angle demanded during the takeoff run before speed reaches TKOFF_ROTATE_SPD. For taildraggers set to 3-point ground pitch angle and use TKOFF_TDRAG_ELEV to prevent nose tipover. For nose-wheel steer aircraft set to the ground pitch angle and if a reduction in nose-wheel load is required as speed rises, use a positive offset in TKOFF_GND_PITCH of up to 5 degrees above the angle on ground, starting at the measured pitch angle and incrementing in 1 degree steps whilst checking for premature rotation and takeoff with each increment. To increase nose-wheel load, use a negative TKOFF_TDRAG_ELEV and refer to notes on TKOFF_TDRAG_ELEV before making adjustments.

Increment	Range	Units

YAW_RATE_SMAX: Yaw slew rate limit

Note: This parameter is for advanced users

Sets an upper limit on the slew rate produced by the combined P and D gains. If the amplitude of the control action produced by the rate feedback exceeds this value, then the D+P gain is reduced to respect the limit. This limits the amplitude of high frequency oscillations caused by an excessive gain. The limit should be set to no more than 25% of the actuators maximum slew rate to allow for load effects.
