10% additional torque may be required for maneuvering and hovering with a ______ crosswind.

10% additional torque may be required for maneuvering and hovering with a ______ crosswind.

• A. Left
• B. Right
• C. No crosswind
• D. High crosswind

Answer: (A)

When hovering or maneuvering, the helicopter must produce enough torque to overcome both rotor drag and any yaw moment created by the wind. A crosswind introduces a side force that tends to yaw the helicopter, so the anti-torque system has to work harder to keep the nose pointing where you want. A crosswind from the left creates a yaw tendency that loads the anti-torque system more heavily, requiring extra main-rotor power to maintain position and control. In practice, about 10% more torque may be needed in a left crosswind to compensate for that added load, whereas no crosswind uses baseline torque and a stronger crosswind would demand even more.
