Which term describes the transmittal of rotor blade aerodynamics to the cockpit controls?

• A. Feedback
• B. Disk Area
• C. Dual Rotor
• D. Disk Loading

Answer: (A)

Feedback is the transmittal of rotor blade aerodynamics to the cockpit controls. When you move the cyclic or collective, the rotor blades’ pitch changes create aerodynamic forces that travel back through the rotor system and are felt by the pilot as stick forces and vibrations. This creates a closed-loop where the pilot senses how the rotor is responding and adjusts inputs to achieve the desired motion. The other terms describe different concepts: disk area is simply the rotor disk size, disk loading is weight per rotor area, and dual rotor refers to helicopters with two main rotors; none of these describe the felt transmission of rotor aerodynamics to the controls.
