FAA Ground School Practice Test

What is the purpose of a taxiway directional sign when turning onto a taxiway from another taxiway?

1. Indicates the speed limit on the taxiway

2. Indicates designation and direction of taxiway leading out of an intersection

3. Indicates the position of the aircraft on the ground

4. Indicates the active runway for departures

The correct answer is: Indicates designation and direction of taxiway leading out of an intersection

The purpose of a taxiway directional sign when turning onto a taxiway from another taxiway is to indicate the designation and direction of the taxiway leading out of an intersection. These signs are crucial for aircraft navigation on the ground, especially at busy airports where multiple taxiways intersect. The sign will typically display the alphanumeric identifier of the taxiway being entered, along with arrows indicating the direction of travel. This information helps pilots to confirm their intended route, which is particularly important in maintaining efficient and safe airport operations. While other options reference various aspects of airport operations, they do not pertain specifically to the function of taxiway directional signs. For example, speed limit indications are vital for safe taxiing but are typically conveyed by different types of signage. Similarly, aircraft position on the ground is tracked through different methods and is not indicated by these directional signs. Meanwhile, the active runway information is communicated through specific airport signage and air traffic control, distinguishing its purpose from that of taxiway directional signage.
