What is Reil aviation?
The Runway End Identifier Lights (REIL) system provides rapid and positive identification of the end of the runway. The system consists of two synchronized, unidirectional flashing lights.
What color are Reil lights?

How are runways numbered?
All runways are numbered based on the magnetic azimuth (compass bearing) in which a runway is oriented. Runway numbers are determined by rounding the compass bearing of one runway end to the nearest 10 degrees and truncating the last digit, meaning runways are numbered from 1 to 36—as per the diagram below.
How are REILs used to identify the runway?
REILs (Runway End Identification Lights) are used to identify the approach end of the runway. The horizontal beam pattern and bright simultaneous flashes helps the pilot identify the runway in use. Three intensity settings allow the approach to be used under changing weather conditions.
What are the lights at the end of the runway?
A REIL system provides a visual marker of the approach end of the runway. The system consists of two synchronized flashing lights positioned on each corner of the runway landing threshold. The horizontal beam pattern and bright simultaneous flashes helps the pilot identify the runway in use.
What should the runway threshold identifier lights look like?
Runway threshold identification lights should be flashing white lights with a flash frequency between 60 and 120 per minute. The lights shall be visible only in the direction of approach to the runway.
What should I look for when approaching a runway?
There are two elements to the approach: the visibility and the Minimum Descent Altitude (MDA)/ Decision Altitude (DA). These values are published at the bottom of the relevant approach chart which is available to the pilots. Sign up for the free daily TPG newsletter for more travel tips!
