noun
aircraft parking apron; apron
Technical term for the paved area at an airport where aircraft are parked, loaded, or refueled. Not a general word for parking lot.
飛行機は駐機場で整備を受けている。
The aircraft is undergoing maintenance on the apron.
駐機場には数機の旅客機が並んでいた。
Several passenger planes were lined up on the apron.
Means parking lot for cars, not aircraft. 駐機場 is specifically for airplanes.
Compound of 駐 (ちゅう, 'to park, stay') + 機 (き, 'aircraft') + 場 (じょう, 'place'). A straightforward modern technical term.
