What does a steady green light signal during taxi indicate?

1. Prepare for takeoff

2. Cleared to taxi

3. Cleared to land

4. Return to starting point

The correct answer is: Cleared to taxi

A steady green light signal during taxi indicates that the aircraft is cleared to taxi. This signal is crucial for communication between ground control and pilots, ensuring that there is a clear understanding of when it is safe to move on the ground. The steady green light serves as a direct instruction from air traffic control that the pilot can proceed along the taxiways to the runway or other designated locations. This signaling is essential in avoiding confusion and maintaining safety on the airport's ground, where the movement of aircraft is tightly controlled to prevent accidents. When a steady green light is indicated, it signifies to the pilot that the route is free of obstruction and it is safe to proceed, differentiating it from other signals that might indicate preparation for takeoff or landing scenarios.
