What does the term "airside" refer to?

The term "airside" specifically refers to the restricted areas of an airport that include runways, taxiways, and ramps. These areas are critical for the operation of aircraft and are subject to strict security regulations to ensure the safe movement of planes and vehicles. Access to these zones is limited to authorized personnel and vehicles that have the necessary Airside Vehicle Operator Permits (AVOP).

In contrast, areas accessible to the public are categorized as "landside," where passengers and visitors can move freely. Areas outside the airport terminal also fall into the landside category, as they are open for public access without any security measures typically associated with airside operations. Green spaces within the airport campus are usually not included in airside classifications either, as these areas serve different purposes and do not directly support aviation activities. Understanding the definition of "airside" provides clarity on airport operations and the importance of security in those restricted areas.
