SFL stands for which lighting component in the approach lighting system?

• A. Sequenced Flashing Lights (Rabbit Lights)
• B. Synchronized Forward Lighting
• C. Simple Flare Lighting
• D. Sequential Flight Lights

Answer: (A)

Sequenced Flashing Lights, often called rabbit lights, are the lights in the approach lighting system that flash in a predetermined sequence from the far end toward the runway to give pilots distance and alignment cues during instrument approaches. SFL is the standard abbreviation for Sequenced Flashing Lights, the component that helps pilots judge their position as they approach the runway. The other terms aren’t used in standard aviation terminology for this system, so they don’t fit as the official name.
