What is the maximum towing speed for towing a helicopter (HELO)?

• A. 5 knots
• B. 15 knots
• C. 25 knots
• D. 50 knots

Answer: (A)

Towing a helicopter on deck must be done very slowly to keep forces and motion under control. Even with the rotor folded and secured, the helicopter and its gear present wind resistance and mass that translate into tow-line tension whenever you start, stop, or steer, especially with a moving deck and sea state. If you tow faster, small changes in direction or gusts can create large, sudden loads on the nose gear and tow fittings, increase the risk of the helicopter swinging and striking deck equipment or people, and make it hard to respond to any problem. Keeping speed to five knots provides a safe, conservative margin to maintain control, monitor for any shifting loads, and protect both the aircraft and the crew. Higher speeds would unnecessarily amplify those risks, so the maximum is five knots.
