Definition
Paved or otherwise prepared areas at an airport where aircraft are parked, loaded, unloaded, fueled, or serviced. Aprons are not used for takeoff or landing and are typically located adjacent to terminals, hangars, or fixed-base operator (FBO) facilities.
Plain English
The flat, paved areas at an airport where aircraft are parked and where passengers board, fuel is loaded, and ground services happen. They are separate from the runways and taxiways used for moving and flying.
Context Anchor
Seen on airport sketches and airport diagrams, especially around terminals, hangars, and fuel or service areas.
Derivation
From the Old French naperon, meaning a small cloth laid in front of something to protect it. The word came to describe any flat area laid out in front of a building — and at airports, it describes the paved area laid out in front of hangars and terminals.
Why Pilots Care
Aprons are busy areas with parked aircraft, ground vehicles, fuel trucks, and people. Pilots must taxi carefully, follow ground markings, and watch for obstacles and wingtip clearance when entering or leaving the apron.
Intuition Check
Do not read “aprons” as clothing. On an airport diagram, aprons are aircraft parking and service areas on the ground.
Example Sentence 1
After landing, the pilot taxied off the runway and followed ground control's instructions to a parking spot on the apron.
Example Sentence 2
Airport diagrams show the location of aprons so pilots can plan parking and avoid crossing active taxiways.
