4.2. Loss of Video

Indicator: Video signal is too weak to be usable or consists entirely of static, but aircraft
OSD data continues to update and
OSD data is not updating and/or
has been lost as well – refer to Section 4.3. Weak C2 Link (pg. 42).
Response Action: Increase the altitude of the aircraft and after reaching a safe height,
move it closer to the GCS. If the aircraft is not in GCS line-of-sight, the operator must regain
LOS if possible. Ensure the GCS-D video receiver antenna is pointed in the direction of
the aircraft. If the aircraft video feed still does not reappear, ensure the vehicle is at an
altitude clear of potential obstructions and press the HOME button to return it to the home
location.

4.3. Weak C2 Link

Indicator: "Warning: Weak C2
as the heading and altitude graphics, have stopped updating. Often video reception is
poor or non-existent as well.
Response Action: Increase the aircraft altitude and after reaching a safe height, move it
closer to the GCS. If weak C2 link persists, the vehicle will enter lost communication mode
after 10 seconds. It will climb to an altitude of approximately 300 feet AGL and then begin
to fly back to the home location. If control communications are regained en route to the
home location (indicated by the disappearance of the "Weak C2 link" warning and
resumption of aircraft OSD data updates), the operator may wiggle the left joystick,
reestablishing control of the aircraft and redirect it by using the joysticks.
