Definition
Lights at an airport, often arranged in a distinctive pattern or sequence near the approach end of a runway, that help a pilot identify and locate the airport or runway from the air, particularly at night or in reduced visibility.
Plain English
Lights that make an airport or runway easier to spot from the air so the pilot knows where to head for landing.
Context Anchor
Seen in normal approach and landing procedures, especially when configuring the airplane and increasing visibility to other traffic near the airport.
Derivation
From the Latin 'recognoscere,' meaning 'to know again' or 'identify.' These lights help the pilot recognize—identify and confirm—the airport among other ground lighting.
Why Pilots Care
Turning on recognition lights during night approaches or in busy airspace reduces the chance of mid-air conflict by making the aircraft stand out against city lights or dark terrain.
Intuition Check
Recognition lights do not mean lights used mainly to identify the type of airplane. Here, they mean lights used to help others see the airplane and recognize it as traffic.
Example Sentence 1
On the night cross-country, the recognition lights helped the student spot the airport against the bright city background.
Example Sentence 2
During a dusk arrival the instructor reminded the student to activate the recognition lights before turning base to improve visibility to other pilots in the pattern.
