What system provides landing gear position monitoring?

The correct answer provides insight into the specific functionality associated with landing gear position monitoring systems within aircraft operations. The Proximity Sensor System (PSS) utilizes sensors that detect the landing gear's position by detecting proximity to various components or parts within the landing gear mechanism. This system plays a crucial role in ensuring that the landing gear is in the correct position during operations, providing real-time feedback to the flight crew and other monitoring systems.

The Proximity Sensor System's reliance on sensors to monitor the physical state of the landing gear allows for accurate and timely reporting, which is essential for safe aircraft operations, particularly during critical phases such as landing and takeoff.

While other systems like the Landing Gear Control System (LGCS) and Gear Indicator Control Module (GICM) also relate to the management and indication of landing gear status, the PSS specifically focuses on the physical detection of gear position, distinguishing it as the correct answer. The Axle Position Sensor (APS) does not primarily serve the purpose of monitoring landing gear position but instead relates to the monitoring of wheel axle parameters.
