Runway End Identifier Lights (REIL)
The Runway End Identifier Lights (REIL) are a pair of flashing lights that are placed laterally on each side of the runway threshold. Their primary function is to provide a clear and rapid identification of the approach end of a particular runway to pilots as they make their final approach.
REIL works by synchronizing both lights to create a distinct and unmistakable flash pattern, which can be easily recognized by pilots. The lights are typically white, but can also be yellow or red, depending on the airport and the type of runway.
These lights are especially useful in low visibility conditions such as fog, rain, or snow, where pilots may have difficulty in identifying the approach end of the runway. By providing a clear indication of the runway threshold, REIL ensures a safer landing experience for pilots and passengers alike.
Overall, the Runway End Identifier Lights are an important safety feature that help pilots to properly identify runway thresholds and approach ends. This, in turn, decreases the chances of incidents and accidents during landings, enhancing aviation safety standards across the board.
