Which aspect does Airside exclude?

Airside refers specifically to the areas of an airport that are accessible only to authorized personnel, which typically includes the runway zones, taxiways, and ramp areas where aircraft are parked, loaded, and serviced. In this context, public terminal areas are part of the landside portion of the airport, which is accessible to the general public, including passengers and visitors.

The airside includes the areas where aircraft operations occur, such as runway zones and hangar space for aircraft, as well as designated parking areas for staff who are authorized to work in those operational areas. Therefore, the public terminal areas, which serve as the interface between passengers and the airlines, are not part of the airside—they are designed for public access and are therefore excluded.
