Using DO_LAND_STARTΒΆ
The DO_LAND_START mission item can be used for two purposes:
In Plane, to provide an automatic re-attempt for an aborted NAV_LAND autolanding in a mission. (See How to Abort an Autolanding)
To provide an automatic landing sequence for RTLs in Plane or as a failsafe action in Copter.
Note
in Rover, it can be used, but only via Scripting call to start the landing sequence.
You can optionally include more than one DO_LAND_START
mission item in your mission. If that is done then the latitude/longitude/altitude of the DO_LAND_START
mission items is used to choose which landing sequence to use. The DO_LAND_START
closest to the current location in all three dimensions is used. This can be useful if you have multiple landing sequences for different wind conditions or different areas.
Note
If you are already in a landing sequence (NAV_LAND or DO_START_LAND sequence), then it will continue.
