Which term refers to a rotor that serves either to counteract the main rotor torque or to maneuver the rotorcraft about axes?

• A. Auxilliary Rotor
• B. Canard
• C. Area Navigation (RNAV)
• D. Approved

Answer: (A)

The main idea is a secondary rotor that provides control beyond the primary rotor. An auxiliary rotor is a rotor that serves to counteract the main rotor’s torque and/or help maneuver the rotorcraft about its axes. By counteracting torque, it prevents the fuselage from spinning unintentionally, and it can also aid in directing yaw, pitch, or roll depending on how it’s mounted and controlled. Other terms here don’t describe a rotor used for this purpose: a canard is a forward wing for stability, RNAV is a navigation method, and “approved” isn’t related to rotor systems.
