Plain English Meaning

The hard, paved area at an airport where planes sit on the ground — for parking, fueling, or loading passengers and bags.

Full Definition

A paved surface at an airport where aircraft are parked, fueled, loaded, or otherwise handled on the ground. In common usage, the word covers ramps, aprons, and other hard-surfaced areas outside the runways and taxiways.

Context Anchor

You may hear this word when discussing airport ground operations, ramp safety, passenger movement near aircraft, or hazards around parked airplanes.

Derivation

Short for tarmacadam, a road surface invented in the early 1900s by mixing tar with crushed stone (macadam, named after Scottish engineer John McAdam). The name stuck even though most modern airport surfaces are concrete or rather than true tarmac.
