FAA Ground School Practice Test

A steady green light signal from the control tower to an aircraft in flight indicates that the pilot is:

1. Cleared for takeoff

2. Cleared to land

3. To return to the original point of departure

4. To exercise caution during flight

The correct answer is: Cleared to land

A steady green light signal from the control tower indicates that the pilot is cleared to land. This signal is part of the aeronautical lighting system used for communication between air traffic control and pilots. In this context, the steady green light serves as an unambiguous instruction that the aircraft may proceed to land safely at the airport. Understanding the functions of different light signals is crucial for pilots, especially when visual cues are necessary for safe operations. A steady green light specifically confirms that there are no obstacles or reasons to hold back from landing, affirmatively guiding the pilot to descend and approach the runway without concern.
