What does "active runway" refer to in aviation terminology?

• A. The runway currently designated for use by approaching or departing aircraft.
• B. A runway that is only used for emergency landings.
• C. The runway that is closed for maintenance.
• D. A runway that is used for taxiing only.

Answer: (A)

In aviation terminology, "active runway" specifically refers to the runway that is currently designated for use by arriving or departing aircraft. This definition is essential for air traffic control operations, as it helps in maintaining safety and efficiency during takeoff and landing sequences. Knowing which runway is active allows pilots and air traffic controllers to coordinate movements accurately and manage traffic appropriately.

The importance of this term lies in its direct influence on airport operations; it ensures that all aircraft are aware of which runway they can use and helps avoid potential conflicts. Other runways at the airport may be in use for different purposes, such as taxiing or being closed for maintenance, but only the active runway is in service for takeoff or landing operations at any given time.
