Where can you find the standard aircraft taxi hand signals?

The standard aircraft taxi hand signals are detailed in the Aeronautical Information Manual (AIM). The AIM serves as a comprehensive resource that provides essential information concerning aeronautical practices, regulations, and signals used in aviation. Among its many topics, it includes guidelines for ground operations, which cover the prescribed hand signals that ground crew members use to ensure safe movement of aircraft on the ground.

While other resources, like the pilot's operating handbook or official FAA publications, may contain information pertinent to flight operations, the AIM is specifically designed to communicate vital information about aviation procedures, including hand signals crucial for ground operations. Consequently, consulting the AIM is the most reliable way to access standardized information on taxi hand signals used universally in the aviation industry.
