Definition
Defined rectangular surfaces on an airport prepared for the landing and takeoff of aircraft, identified by numbers based on their magnetic heading and described by physical characteristics such as length, width, and surface type.
Plain English
The strips of pavement or other prepared ground at an airport that aircraft use to take off and land.
Context Anchor
Seen on airport diagrams, airport signs, charts, and GPS nearest-airport pages that show what landing options an airport has.
Derivation
From 'run' (to move quickly along the ground) plus 'way' (a path or route). Literally, the path along which an aircraft runs to gain or lose flying speed.
Why Pilots Care
Runway information helps pilots evaluate suitable landing sites, especially during diversions or emergencies, by confirming length, alignment, and surface condition.
Intuition Check
Do not think of a runway as just any flat open area. In aviation, a runway is a prepared and identified airport area meant for aircraft takeoff and landing.
Example Sentence 1
The GPS nearest airport page listed the available runways along with their lengths so the pilot could choose a suitable one for the diversion.
Example Sentence 2
Strong crosswinds required the pilot to choose the longest runway aligned closest to the wind direction.
