Acronyms that contain the term airport apron 

Airport apron

The airport apron, flight line, or ramp is the area of an airport where aircraft are parked, unloaded or loaded, refilled, or boarded. Although the use of the apron is covered by regulations, such as lighting on vehicles, it is typically more accessible to users than the runway or taxiway. However, the apron is not usually open to the general public and a permit may be required to gain access. By extension, the term apron is also used to identify the air traffic control position responsible for coordinating movement on this surface at busier airports. The use of the apron may be controlled by the apron management service (apron control or apron advisory) to provide coordination between the users. The apron is designated by the ICAO as not being part of the maneuvering area. All vehicles, aircraft and people using the apron are referred to as apron traffic.
