[5c] Flight Modes

Modified flight modes included in AC3.3* PL firmware

📘

Flight Mode descriptions (below) apply to modified AC3.3* Firmware

Currently, the ArduPilot master code (3.4-beta) includes Precision Landing in only the LAND flight mode.

LAND: Centers copter over IR target while descending at the descent rate prescribed in the parameter: PREC_LND SPEED. Applying roll or pitch will immediately disable the automated precision landing control.

LOITER: Centers copter over IR target while holding altitude. Applying roll or pitch will immediately disable the automated precision landing control.

AUTO (LAND): When scripting a mission, the LAND command will center the copter over an IR target while descending at the descent rate prescribed in the parameter: PREC_LND SPEED.

🚧

Be prepared to switch to Stabilize mode if copter behaves abnormally.

For your first flight, you should take off in STABILIZE mode and manually maneuver the copter over the MarkOne beacon. Then, switch the copter into LAND or LOITER mode. If the beacon is in-view of the sensor, you should see the copter respond by moving toward the beacon. Note: if you manually apply roll/pitch after switching into LAND/LOITER, this will disable the automated precision landing control.
