Definition
A specific shade of green defined by FAA color standards for use in aviation lighting, distinct from ordinary green and used in airport lights, beacons, and signals so pilots can identify them reliably from the air, day or night.
Plain English
An official, standardized green color used in airport and aircraft lighting. It looks the same at every airport so pilots always recognize it.
Context Anchor
Seen in airport and navigation lighting discussions, especially when identifying airport beacons at night.
Derivation
Called 'aviation green' because the shade is specified by aviation standards rather than left to the manufacturer. The label is a way of saying 'the green that aviation uses,' to distinguish it from any other green light a pilot might see at night.
Why Pilots Care
Identifying aviation green confirms the start of the landing surface during night or reduced-visibility approaches.
Intuition Check
Do not read “aviation green” as simply “a green-looking light.” Here it means a specific approved green used for aviation signals.
Example Sentence 1
The alternating white and aviation green flashes from the beacon confirmed the field ahead was a lighted land airport.
Example Sentence 2
During the preflight check the crew verified that all threshold lights displayed the correct aviation green.
