FAA Ground School Practice Test

What light signal from the control tower indicates that a pilot is cleared to taxi?

1. Steady green

2. Flashing white

3. Flashing green

4. Steady red

The correct answer is: Flashing green

The correct indication that a pilot is cleared to taxi is represented by a flashing green light signal from the control tower. This signal specifically instructs pilots that they may proceed with moving their aircraft on the taxiways, but it is important to remember that this does not authorize takeoff or landing. Understanding the significance of this signal is crucial for ensuring safe movement in the airport environment. The flashing green light serves as a clear and unambiguous command during operations on the ground, helping to prevent misunderstandings between the control tower and pilots. Other light signals serve different purposes. A steady green light indicates that a pilot is cleared for takeoff, while a steady red light means to stop. A flashing white signal is typically issued to instruct an aircraft to return to its starting point on the airport. Each light pattern has its unique meaning, and recognizing these can greatly enhance safety and efficiency in aviation operations.
