What indicates a jet blast hazard around operational aircraft?

The indication of a jet blast hazard around operational aircraft is signaled by the activation of the aircraft's anti-collision lighting. These lights are designed to enhance the visibility of the aircraft for safety reasons, especially when the aircraft is in motion or preparing for takeoff. When the anti-collision lights are active, this serves as a clear alert to ground personnel and nearby individuals that the aircraft is potentially preparing for operations that may involve jet blasts or other hazardous conditions associated with engine activity.

Jet blast is the high-speed airflow generated by jet engines during operations, which can pose serious risks to anyone nearby. By observing the illuminated anti-collision lights, individuals can recognize the need for caution and maintain a safe distance to avoid injuries. It is an important part of aviation safety protocols that helps ensure the well-being of both ground personnel and airport operations.
