PROCEDURE

GEOCAGE VIOLATION ANNOUNCE

The RPIC is to announce the voice comms “NFA Violation” once emergency conditions are identified using the indications information above.

Uncrew: Return to Home SELECT

Select the Return to Home Button within the Uncrew Mission Console on the RPIC Control Station.

Return to Home Button

Once the command button is selected, a popup window will appear requiring RPIC confirmation. This window will remain displayed until “CONFIRM” is selected or exit (“x”) is pressed.

Return to Home Confirmation

Once the command is confirmed, the aircraft stops performing the mission and begins navigating to the takeoff location. The aircraft maintains its altitude at the defined desired altitude. Uncrew navigates the aircraft so that all NFAs and perimeters are avoided. The Aircraft Status shall be Contingency.

At the takeoff location, the aircraft will land. Precision landing mode shall be automatically attempted during the landing sequence.

Procedure Complete

If Aircraft fails Return to Home:

Uncrew: ALZ SELECT

Select the “ALZ” button within the Uncrew Mission Console on the RPIC Control Station.

ALZ Button

Once the command is selected, a popup window will appear requiring RPIC confirmation. This window will remain displayed until “CONFIRM” is selected or exit (“x”) is pressed.

ALZ Confirmation

Once the command is confirmed, the aircraft stops performing the mission and begins navigating to an Alternate Landing Zone (ALZ). The aircraft maintains its altitude at the defined desired altitude. Uncrew navigates the aircraft so that all NFAs and perimeters are avoided. The Aircraft Status will be Contingency.

At the ALZ, the aircraft will land.

If Aircraft successfully executes ALZ:

VO — RELOCATE TO ALZ

The RPIC shall communicate with the VO which ALZ the aircraft is navigating to in order for the VO to relocate their position.

Procedure Complete

If Aircraft does not divert to ALZ:

AMC: EMERGENCY SHUTDOWN SELECT & CONFIRM

Select the “Emergency Actions” button on the top of the AMC application on the RPIC Tablet. Once pressed, a notification and confirmation popup will appear in the center of the screen.

AMC Emergency Shutdown

After deployment, the aircraft is required to be serviced in accordance with the UMM by qualified maintenance personnel.

WARNING: The Emergency Shutdown command will result in immediate deployment of the parachute. This may result in damage to or destruction of equipment, loss of mission effectiveness, or injury to persons.

Record last known location — NOTE B.A.T.H.S.

The RPIC shall note the last known battery percentage, altitude, current time, heading, and speed of the aircraft reported on the RPIC Tablet. This shall help with the recovery of the aircraft.

Aircraft — SEARCH, RECOVER

The RPIC and/or available crew member(s) will search and recover the aircraft.
