What primary signal does a solid green light convey to pilots?

A solid green light is a signal used in aviation that indicates to pilots they are cleared for takeoff. This signal is crucial, especially during taxi and takeoff phases, as it provides a clear and unambiguous directive to the pilot that they can proceed with their departure.

In the context of airport operations, various colored lights are employed to communicate different statuses to pilots. The solid green light is widely recognized as a positive signal, instilling confidence in pilots about their readiness to safely commence their flight. Understanding these signals is vital for effective communication in the aviation environment, ensuring safety and efficiency in operations.
