Definition
The standardized system of painted markings on runway surfaces and posted signs along runways and taxiways used to identify runways, indicate distances, designate thresholds and touchdown zones, and communicate operational information to pilots during takeoff, landing, and ground movement.
Plain English
The paint on the runway and the signs beside it that tell pilots which runway they are on, where it begins and ends, and other information they need while taxiing, taking off, or landing.
Context Anchor
You see runway markings and signs during taxi, before entering or crossing a runway, during takeoff, and during landing rollout.
Why Pilots Care
They prevent runway incursions and allow safe, orderly ground movement without relying solely on radio instructions.
Analogy
They work much like road lane markings and traffic signs, but at an airport the consequences of missing one can be much more serious because aircraft may be landing, taking off, or taxiing nearby.
Intuition Check
Do not assume runway markings and signs are just visual aids or decoration. In airport operations, they can tell you where you are, where you must stop, and whether you are about to enter a runway.
Example Sentence 1
Before taxiing out, the student reviewed the runway markings and signs in the AIM so she could identify the hold-short line and runway designators at her home airport.
Example Sentence 2
Hold-short markings and signs kept the aircraft clear of the active runway until cleared to cross.
