Definition
An area of land set aside for the takeoff, landing, and ground handling of aircraft, typically including one or more runways or landing surfaces and any associated taxiways, parking areas, or basic support facilities.
Plain English
A piece of ground used for aircraft to take off and land from, along with the surfaces and spaces needed to move and park them on the ground.
Context Anchor
Seen when evaluating possible landing places during an emergency or when identifying nearby airports and landing areas along a route.
Derivation
From 'air' plus 'field' — literally a field used for aircraft. The term dates from early aviation when most flying was done from open grass fields rather than paved runways, and it has stuck as a general word for any basic landing ground.
Why Pilots Care
In an emergency, recognizing an airfield clarifies what services may or may not be available compared to a full airport.
Intuition Check
Do not read “airfield” as just an open grassy field. In aviation, it means a place used or intended for aircraft takeoffs and landings.
Example Sentence 1
With the engine running rough, the pilot identified a small airfield ahead and set up for a precautionary landing.
Example Sentence 2
Many airfields lack fuel, lighting, or maintenance services found at larger airports.
