What are parking areas for aircraft away from terminals called?

Parking areas for aircraft away from terminals are referred to as an apron. This term describes the designated area where aircraft are parked, loaded, unloaded, refueled, and serviced, but it is not directly connected to the terminal buildings. The apron serves as a critical zone in airport operations, facilitating the efficient handling of aircraft in a safe manner.

The concept of an apron encompasses the space that allows for various ground services to be performed, including baggage handling, catering, and maintenance activities, making it an integral part of airport infrastructure. While the term "ramp" is sometimes used interchangeably with "apron" in some regions, "apron" is the more widely recognized and used term in aviation terminology.

The incorrect options provided do not adequately capture the specific function or definition associated with aircraft parking areas. A parking plaza is not a standard term in aviation and may refer to a general area for vehicles rather than aircraft. Hangar space refers specifically to sheltered facilities designed for storing and maintaining aircraft, which is distinct from the apron area.
