Paparazzi allows you to define three modes, MANUAL, AUTO1 and AUTO2 , which are associated to a 3-position switch of your remote.
Because especially rotorcraft can be operated in multiple modes, you can define the mapping to these three easily switchable modes in your airframe file. Moreover, the mode associated to AUTO2 can be changed in the Settings tab of the GCS.
In the following text, the typical configuration is described, which is also why (legacy reasons) the three modes were named as they were named.
The MANUAL flight mode is for directly controling your airframe by your transmitter.
Caution! Please note that any trims and deflections set in your airframe config file still apply.
When flying in Manual mode please consider the failsafes.
The AUTO1 is typically used for controller stabilized flight.
Although the autopilot will keep the airframe level and stabilized, you need to steer the airframe yourself, ie. where you want it to go.
When flying in Auto 1 mode please consider the failsafes.
In AUTO2 your aircraft is typically fully autonomous in stabilization and navigation.
You are not required to steer or stabilize the aircraft via your radio.
