Which unit is primarily responsible for sensing gear position to control gear operation?

• A. Proximity Sensing Electronic Unit (PSEU)
• B. Gear Position Sensor
• C. Landing Gear Control Unit
• D. Brake Control Unit

Answer: (A)

Gear position is determined by processing signals from proximity switches on the landing gear. The Proximity Sensing Electronic Unit acts as the central processor for that information, taking the sensor signals, determining whether the gear is up, down, or in transit, and then sending the appropriate commands to the landing gear actuators while also providing position status to the cockpit indicators. The physical gear position sensors supply the data, but it’s the PSEU that primarily interprets that data and controls gear operation. The Landing Gear Control Unit handles sequencing and interlocks, not the primary sensing, and the Brake Control Unit is unrelated to gear position sensing.
