Definition
The painted lines, numbers, letters, and symbols on runway and taxiway surfaces that identify the pavement, show where aircraft may operate, indicate hold positions, and convey operational information such as runway designation, centerline, threshold, and taxi routing. Runway markings are normally white; taxiway markings are normally yellow.
Plain English
The painted lines and symbols on the ground at an airport that tell pilots which strip of pavement is the runway, which is a taxiway, where to stop, and how to get from one place to another safely.
Context Anchor
You encounter runway and taxiway markings during airport operations training, while taxiing, before takeoff, after landing, and when studying airport surface movement.
Why Pilots Care
Correct interpretation prevents runway incursions, wrong-surface landings, and loss of situational awareness on the airport surface.
Intuition Check
Do not think of these as decoration or general pavement paint. In aviation, runway and taxiway markings are standardized instructions painted on the airport surface for safe aircraft movement.
Example Sentence 1
The instructor pointed out the runway and taxiway markings during the airport diagram briefing so the student could identify hold-short lines before taxiing.
Example Sentence 2
White runway numbers and centerline stripes helped the pilot confirm they were aligned with the correct runway after landing.
