Which area of an airport is referred to as 'Airside'?

The term "Airside" refers to areas of the airport that are specifically designated for aircraft operations and passenger activities once they have passed through security. This includes the runways, taxiways, and areas around the aircraft, as well as boarding gates where passengers access the planes. These areas are generally restricted to authorized personnel and ticketed passengers only, ensuring safety and security around aircraft operations.

The choice focusing on areas that support aircraft activities accurately encapsulates the essence of airside locations. These spaces are integral to the operational functionality of the airport, allowing for aircraft movement, ground handling, and other essential activities that keep air transport running smoothly. Understanding the distinction between airside and landside operations is crucial for anyone involved in airport functions, as it directly impacts safety protocols and operational efficiency.
