Inconsistent gear position indications during landing gear extension most likely indicate?

• A. The aircraft is currently in flight.
• B. Gear doors are closed.
• C. A fault in sensor signals or wiring.
• D. Parking brake is engaged.

Answer: (C)

Inconsistent gear position indications during extension point to a problem in the sensing system itself. The gear and door position are monitored by sensors on each leg and by door sensors, with their signals feeding the cockpit indicators and the gear logic. If one sensor or its wiring is faulty, or a connector is loose, the signals can disagree or fluctuate, producing inconsistent readings even though the gear may be moving as it should. The issue is electrical/signal integrity, not the aircraft’s flight status or the physical state of the doors or parking brake. A fault in sensor signals or wiring best explains the erratic indications.
