What are the runway edge lights for a displaced threshold?
What are the runway edge lights for a displaced threshold? Normally, runway edge lights are white in colour. However, in the case of a displaced threshold, the lights between the beginning of the runway and the displaced threshold are red in the approach direction.
What are the flashing lights at end of runway?
Runway End Identifier Lights (REIL) REILs are installed at many airfields 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.
