What defines an aerodrome?

An aerodrome is defined as any defined area on land or water that is used for the arrival, departure, and servicing of aircraft. This includes not only airports with passenger terminals but also various other installations that may support aviation activities.

Aerodromes can include runways, taxiways, and other facilities that accommodate different types of aircraft operations, such as general aviation, cargo flights, and even some military operations. The versatility of the term "aerodrome" allows it to encompass a wide range of facilities rather than being limited to a specific aspect of aviation, like passenger handling or military use.

In contrast, areas dedicated solely to passenger terminals, aviation repair, or military operations do not capture the full breadth of what an aerodrome is classified as. Each of those options delineates a more narrow focus that does not represent the comprehensive nature of areas designated for aircraft-related activities. Thus, the definition that encompasses any area used for the various functions involving aircraft clearly stands out as the correct interpretation.
