Definition
A large enclosed building used to house, store, maintain, or repair aircraft.
Plain English
A big shed or building where airplanes are kept indoors, usually for storage, protection from weather, or maintenance work.
Context Anchor
You will see this word when reading about airport facilities, preflight preparation, aircraft storage, and moving an airplane on the ground.
Derivation
From the Old French 'hangard,' meaning a shelter or enclosure. The aviation use carried the same idea forward — a covered shelter, just sized for aircraft instead of livestock or carts.
Why Pilots Care
A hangar affects where an aircraft is parked, how it is protected from weather, and how carefully it must be moved near buildings, doors, people, and other aircraft.
Intuition Check
Do not confuse hangar with hanger. A hangar is a building for aircraft; a hanger is something used to hang clothes.
Example Sentence 1
After the flight, the pilot taxied back and parked the airplane in the hangar.
Example Sentence 2
The mechanic performed the preflight inspection inside the hangar before the student pilot arrived.
