Control commands
Control commands are used to trigger particular behaviours of the UAS during flight. The detailed performance after triggering each button may vary per UAS model. Additional details and particular precautions are given in the UAS Flight Manual. In particular:
- Turn direction and space required
- Margins required with geocage/pregeocage
- Altitude requirements
- Any other applicable precautions or requirements
The colour of the buttons indicates the number of times a button needs to be clicked on in order to be executed. This is meant to avoid human errors when monitoring an operation. Yellow buttons require two clicks and red buttons require three clicks.
From left to right, the commands are:
- Continue operation (yellow, double click): cancels any contingency/emergency behaviour (except "Terminate") and continues the operation (returning to the nominal flight plan).
- This button is only available when a contingency/emergency command is triggered.
- Buttons triggered are disabled until the UAS switches to a different behaviour (e.g.: after continuing the operation or triggering another command).
- Hold (yellow, double-clicks): enters in hover mode (multicopter configuration) or loiter (fixed-wing configuration).
- RTO or Reverse to Takeoff (yellow, double-click): returns to takeoff by following a reversed flight plan.
- SRP or Smart Rally Point (red, triple-click): the UAS goes to the closest Rally Point (takeoff and landing positions included) and lands in multicopter configuration (after doing a back transition, if applicable).
- Land (red, triple-click): the UAS lands as soon as possible (requires a back transition if the vehicle is flying in fixed-wing configuration).
- Terminate drone with/without parachute (red, triple-click): terminates the engines (and triggers the parachute, only if enabled).
- This action is definitive.
- Depending on the safety configuration of the flight plan, the icon will show a cross (termination without parachute) or a parachute (termination with parachute).
