Which flight performs diagnostic on and off equipment maintenance on communication navigation, electronic warfare, weapons control, guidance control, airborne photographic, and sensor systems, aircraft instruments and flight controls?

• A. TMDE
• B. Maintenance Supervision
• C. Avionics Flight
• D. Propulsion Flight

Answer: (C)

Avionics Flight handles the electronic systems that keep the aircraft capable and aware: communication, navigation, electronic warfare, weapons control, guidance, airborne photography, sensors, aircraft instruments, and flight controls. Technicians in this flight diagnose faults and perform maintenance on equipment both installed in the aircraft (on-equipment) and removed for testing or repair (off-equipment). This combination—specialized troubleshooting, calibration, and repair of all avionics and associated flight-control sensors—fits the unit responsible for this scope of work. The other options don’t apply: TMDE refers to the test equipment and the tools used to diagnose rather than the maintenance team; Maintenance Supervision is the administrative oversight and does not perform hands-on diagnostics; Propulsion Flight deals with engines and propulsion systems, not avionics.
