When should the Air Traffic Control Tower Light Gun Signal be used?

The use of the Air Traffic Control Tower Light Gun Signal is essential when there is a loss of any two-way communication with the Air Traffic Control Tower (ATCT). This situation could arise for various reasons, such as equipment failure or interference. The light gun signals serve as an alternative means of communication, allowing controllers to convey instructions to pilots visually.

When radio communication is compromised, pilots must rely on these signals to ensure safe operations and adherence to air traffic control directives. For example, the light gun can provide different color signals indicating whether a pilot should stop, taxi, take off, or land. Utilizing this system effectively helps maintain safety and order in the airspace.

While severe weather conditions may impair radio communication, it is crucial to emphasize that the light gun signals themselves are specifically designed as a backup communication method. This reinforces the importance of the correct understanding and application of air traffic control protocols during any disruption in communication.
