What is the definition of an aerodrome?

An aerodrome is defined as an area used for aircraft arrival and departure, which encompasses not only the runway and taxiways but also related facilities that support various aviation operations. This includes structures like terminals, hangars, maintenance buildings, and other infrastructure necessary for the functioning of air traffic.

Understanding that an aerodrome serves broader purposes than just being a space for parking or passenger waiting is essential. It is a complete ecosystem that facilitates the operations surrounding air travel, including takeoffs and landings, and supporting services. In contrast, the other options focus either on specific functions that do not encompass the full scope of aerodromes or are limited to parts of air travel that do not include the actual air traffic aspect, leading to an incomplete definition.
