Final answer:
The statement about 'airside' is true; it encompasses all areas of an airport necessary for aircraft operations like runways, ramps, and taxiways, which are all pivotal to civil airline infrastructures and commercial air traffic.
Step-by-step explanation:
The statement that airside includes facilities and physical property of the airport to facilitate aircraft operations is A. True. The term 'airside' refers to all areas of an airport that are accessible to aircraft, including runways, taxiways, ramps, and the apron area. These areas are crucial for the take-off, landing, and parking of aircraft. Alongside the airside, airports also have a landside, which includes components such as parking lots, check-in counters, security checkpoints, and baggage claim areas. The airside is an essential part of the development of a civil airline infrastructure, working in conjunction with the terminals, which allow for quick and efficient boarding of airplanes and handling of luggage, thereby facilitating commercial passenger air traffic.
