What does the 'F' stand for in runway beacon characteristics?

The 'F' in runway beacon characteristics stands for 'Fixed.' Runway beacons provide important information to pilots about the location and identification of runways, and they may exhibit different characteristics to indicate specific types of runways.

A 'Fixed' beacon emits a continuous light, which is crucial for helping pilots locate runways, especially during low visibility conditions. This characteristic indicates a permanent installation and provides a clear, steady signal that is easily identifiable.

Recognizing the significance of beacon characteristics, pilots are trained to understand how these signals aid in navigation and enhance safety during approach and landing phases. The presence of a fixed beacon reinforces the idea of a stable, reliable point of reference for pilots as they navigate towards the runway.
