How should you signal a pilot to taxi if brakes are not available?

To effectively signal a pilot to taxi in the absence of brakes, it's important to utilize clear and unambiguous communication methods that ensure safety and clarity in understanding. Signaling to taxi in circles is a practical method in situations where the pilot cannot stop or slow down due to brake failure. This approach helps create a controlled environment to guide the aircraft towards an open area or runway where it can safely maneuver without risking collision or further complications.

Using this signaling strategy allows the pilot to maintain some level of control over the aircraft's movement, especially in busy or congested areas. It is crucial as it minimizes potential hazards while also enabling ground crew to manage the situation effectively.

Other methods, while useful in different contexts, may not provide the same level of clarity or safety in a scenario where brakes are inoperative. For instance, light signals and loudspeakers may not convey the urgency or specific instructions as effectively, especially under certain visibility conditions or in noisy environments. Similarly, waving hands vigorously might lead to confusion or misinterpretation of intentions, which is not ideal during critical operations like taxiing.

Therefore, signaling to taxi in circles is a sound and strategic choice in handling instances of brake failure, enhancing safety protocols on the airfield.
