Definition
Painted lines, symbols, and words on airport surfaces that identify runways, taxiways, holding positions, and other operational areas, and that direct the movement of aircraft on the ground. Standard colors and patterns are used so that the same markings mean the same thing at every airport: white markings designate runway features, yellow markings designate taxiway features and direction, and red is used on signs and certain holding-position markings.
Plain English
The painted lines and symbols on the ground at an airport that tell pilots where they are, where they can go, and where they must stop.
Context Anchor
Seen while taxiing, entering or crossing a runway, parking on a ramp, or following ground instructions at an airport.
Why Pilots Care
Correct interpretation prevents runway incursions and ensures the aircraft stays on the intended path.
Analogy
They work much like lane lines and painted arrows on a road, but at an airport they carry aviation-specific meanings that pilots are expected to follow.
Intuition Check
Do not treat pavement markings as simple decoration or general guidance. On an airport, they are part of the traffic-control system for aircraft and vehicles on the ground.
Example Sentence 1
Before crossing the hold-short line, the pilot stopped and confirmed the taxi clearance, following the pavement markings up to the edge of the runway.
Example Sentence 2
Blue pavement markings along the taxiway edge guided the aircraft safely at night.
