What type of beacon or warning system should vehicles use while operating in the Controlled Movement Area (CMA)?

In a Controlled Movement Area (CMA), the use of a Lighting Emitting Diode (LED) or rotating beacon or emergency warning flashers is essential for maintaining safety and visibility. These lights are bright and can be seen from a distance, effectively alerting pilots, ground controllers, and other personnel to the presence of vehicles operating in critical areas of the airfield.

The specific use of LED or rotating beacons is important because they provide a clear indication of a moving vehicle’s presence, enhancing situational awareness, especially in environments with high operational tempo or during low visibility conditions. This visibility is crucial for preventing accidents and ensuring that all personnel and aircraft can safely navigate the airfield.

While other options like flashing lights may seem useful, they often do not convey the same clear message or visibility as an LED or rotating beacon. Standard headlights and reflective tape do not provide the same level of warning; headlights are intended for driving and may not be seen from a distance, while reflective tape serves to enhance visibility of a stationary object rather than alerting others of a moving vehicle. Thus, the specified warning systems are strategically employed to ensure optimal safety in the CMA.
