FAA Ground School Practice Test

What does a closed runway indicate on an airport diagram?

1. It is safe for use during emergencies

2. It is not available for aircraft operations

3. It is only for service vehicles

4. It is functional but restricted

The correct answer is: It is not available for aircraft operations

A closed runway on an airport diagram clearly indicates that it is not available for aircraft operations. This designation is important for pilots and ground personnel as it signals that the runway should not be used for takeoffs, landings, or any other aircraft movements. Typically, a closed runway will be marked in a specific way on the airport diagram, often with a distinctive symbol or color to ensure visibility and prevent accidental use. This helps maintain safety and efficiency at the airport, allowing operations to smoothly continue on the available runways while avoiding potential hazards associated with using a closed runway. Understanding this distinction is vital for flight planning and air traffic management, ensuring that all personnel are aware of the current status of the runways at the airport. The other options do not accurately represent the implications of a closed runway. Options suggesting that a closed runway could be used for emergencies, service vehicle access, or is functional but limited do not align with the operational standards and safety protocols established for airport operations.
