What is a common signal used by ramp personnel to indicate that an aircraft is ready to be pushed back?

The choice of pushback signal using hand gestures is essential as it provides a clear and direct way for ramp personnel to communicate with the flight crew during the pushback process. Hand signals are a widely accepted standard in the aviation industry because they allow for visual communication that can be easily understood, even in situations where radio communication may have limitations due to noise or interference.

Using hand gestures helps to ensure that the aircraft is safely and effectively maneuvered away from the gate, allowing for the safe operation of the pushback vehicle. This method of communication is particularly effective because it can be seen by the pilots and others involved, creating a safe environment for the pushback operation.

While other methods of communication, such as radio communication or flashing lights, are also utilized within the ramp operations, the reliance on hand gestures during pushback is crucial due to their ability to provide immediate and visual confirmation of readiness. Therefore, hand gestures are integral to the pushback process, ensuring clarity and safety in operations.
