Which publication contains the standard FAA hand signals for taxi signalmen?

The FAA Airman’s Information Manual (AIM) is the correct publication that contains the standard FAA hand signals for taxi signalmen. The AIM serves as a comprehensive guide for pilots and includes critical air traffic control procedures, flight regulations, safety information, and more. It specifically includes visual signals used in ground operations, which are essential for ensuring clear communication between ground personnel and pilots, especially in busy airport environments.

Other publications such as the FAA Pilot's Handbook primarily focus on piloting techniques, the FAA Maintenance Manual addresses maintenance practices and procedures, and the FAA Flight Operations Handbook focuses on the operational aspects of flight and can involve broader guidance on flight operations but does not specifically detail the hand signals for taxi signalmen. Thus, for those needing to understand or reference the hand signals applicable to ground operations, the AIM is the appropriate source.
