Advanced Ground Instructor Practice Test

What is the purpose of holding lines at taxiway intersections?

To indicate the start of a runway.

To regulate vehicle traffic on the airport.

To guide pilots for safe taxiing and clearances.

The purpose of holding lines at taxiway intersections is to guide pilots for safe taxiing and to ensure compliance with air traffic control clearances. These lines are typically painted on the taxiway surface and consist of solid and dashed lines. Pilots are required to stop at these holding lines unless cleared by air traffic control to proceed, helping to prevent runway incursions and maintain the safety of aircraft during ground operations.

Holding lines serve as a critical visual cue for pilots, providing a clear indication of where they must hold their position. This practice minimizes the risk of collisions on the runway and ensures that pilots adhere to the instructions given by air traffic control, promoting overall airport safety and efficiency.
