What aircraft handling signal is indicated by a left arm horizontal in front of the body with a clenched fist and the right hand making an upward motion?

The signal described involves a left arm held horizontally in front of the body with a clenched fist while the right hand is making an upward motion. This specific configuration is associated with the action of "winching up."

In aircraft handling, visual signals play a crucial role in ensuring clear communication between personnel, especially on the flight deck where noise levels can be high and traditional forms of communication might be ineffective. The left hand's clenched fist indicates a firm and steady action, signifying the need for a controlled and deliberate movement, while the upward motion of the right hand reinforces the directive to lift or raise an item, which in this case, refers to a load being winched.

This combination of signals creates a clear and effective visual command for personnel to raise equipment or conduct winching operations, enhancing safety and efficiency on the flight deck. Understanding these signals is essential for Boatswain's Mates and other members of the deck crew as they play a vital role in maintaining operational readiness and safety during aircraft operations.
