Runway End Identification Lights
From Wikipedia, the free encyclopedia
Runway End Identifier Lights (REIL) are installed at many airports to provide rapid and positive identification of the approach end of a particular runway. The system consists of a pair of synchronized flashing lights located laterally on each side of the runway threshold. REILs may be either omnidirectional or unidirectional facing the approach area.
They are effective for:
- Identification of a runway surrounded by a preponderance of other lighting.
- Identification of a runway which lacks contrast with surrounding terrain.
- Identification of a runway during reduced visibility.
