FE stands for which sensor?

• A. Front End Zone Sensor
• B. Final Endurance sensor
• C. Far End Zone RVR Sensor
• D. Flight Envelope sensor

Answer: (C)

FE in this context refers to a specific runway visibility sensor: the Far End Zone RVR Sensor. Runway Visual Range sensors measure how far a pilot can see along the runway, and multiple sensors are placed at different locations along the field to provide coverage for different portions of the runway and for different approaches. The designation Far End Zone RVR Sensor identifies the sensor that monitors visibility at the far end of the runway, which is crucial for operations that rely on that end of the runway and for providing accurate RVR data to pilots and ATC. The other descriptions don’t fit this acronym or the purpose of measuring runway visibility, so they aren’t applicable here.
