The term 'Airport Surface' is composed of two words: TARMAC (6 letters) and Airport. TARMAC is a type of surface material used for airport runways, taxiways, and aprons. It is made up of a combination of asphalt and concrete, which makes it durable and able to withstand the weight of aircraft. Airport is a facility that serves as a hub for air travel, providing services such as passenger and cargo handling, aircraft maintenance, and refueling.
