What does a steady green light indicate on the ground?

A steady green light on the ground indicates that the aircraft is cleared for takeoff. This signal is part of a standardized system used in aviation to communicate instructions to pilots. When the green light is on and steady, it confirms to the pilot that all conditions are favorable for takeoff, and they should proceed accordingly.

The significance of this signal lies in its importance for ensuring safety and coordination on the airfield. It helps to avoid miscommunication that could lead to dangerous situations, especially during critical phases like takeoff. Moreover, the use of clear visual signals, such as a steady green light, is essential for maintaining orderly operations at busy airports.

Other choices, while related to ground operations, do not apply to the meaning of a steady green light. Pilots and personnel are trained to interpret these signals correctly to maintain an efficient and safe flying environment.
