What is the proper sequence of communications between the tow operator and the marshaller during pushback?

• A. Acknowledge, then confirm to proceed
• B. Clear indication of intent, continuous two-way communication via radio or signals, acknowledge, and monitor stop points
• C. Initiate movement on visual cues only
• D. Only marshal signals, no radio used

Answer: (B)

The main concept being tested is the need for clear, continuous two-way communication between the tow operator and the marshaller during pushback to keep the maneuver safe. The correct sequence starts with a clear indication of intent to begin movement, followed by ongoing two-way communication using radio or standardized signals, with explicit acknowledgment of each instruction, and active monitoring of stop points to ensure the aircraft ends at the desired position. This approach ensures both parties are synchronized, can confirm understanding, and can adjust immediately if anything changes, reducing the risk to equipment, personnel, or the aircraft.

Relying on visual cues alone can lead to misinterpretation, and using marshal signals without radio removes a reliable channel for confirming instructions and changes in real time. So the combination of a clear intent, continuous two-way communication, acknowledgment, and monitoring is the safest and most effective method.
