Runway End Identifier Lights are abbreviated as REIL. Which option lists the correct full term?

• A. Approach Lighting System (ALS)
• B. End of Runway Lighting
• C. Runway End Identifier Lights (REIL)
• D. Visual Approach Slope Indicator (VASI)

Answer: (C)

This item tests knowledge of aviation lighting abbreviations and what REIL stands for. REIL is Runway End Identifier Lights, a pair of synchronized flashing lights placed at each side of the runway threshold to give rapid, positive identification of the runway end. They help a pilot recognize the threshold, especially in low visibility or at night, independent of other lighting systems. They are not the same as an Approach Lighting System, which extends along the approach path, nor as a Visual Approach Slope Indicator, which provides glide path guidance. There isn’t a standard term “End of Runway Lighting.” So the full term is Runway End Identifier Lights.
