What is defined as an area used for the arrival and servicing of aircraft?

The correct choice is the term that defines an area used specifically for the arrival and servicing of aircraft. An aerodrome encompasses all the necessary facilities and structures to support the arrival, departure, and maintenance activities of aircraft. This includes not only the runways where aircraft take off and land but also the terminals and other areas dedicated to servicing aircraft.

In contrast, while an airfield refers to the entire area designated for flight operations, it may not encompass all aspects of passenger and aircraft service, which are fundamentally part of an aerodrome's functions. A runway is specifically the strip of land where aircraft land and take off but does not include any services for aircraft. A terminal focuses on accommodating passengers and baggage and is not explicitly tied to the broader context of servicing aircraft. The definition of an aerodrome best captures all the elements involved in the arrival and servicing of aircraft.
