Which statement best describes the primary advantage of wide-chord rotor blades?

• A. Higher engine power requirement
• B. Reduced lift
• C. Increased maneuverability
• D. Increased vibration

Answer: (C)

Wide-chord rotor blades add more surface area, so for the same rotor speed and pitch they generate more lift. That extra lift increases the rotor’s authority to respond to pilot inputs, especially at low speed or in hover, giving the helicopter more responsive cyclic and collective control. The result is greater maneuverability—the ability to perform quicker, tighter turns and more precise attitude changes. The other options describe outcomes that aren’t the primary benefit: requiring more engine power isn’t the typical result of wider blades, reduced lift contradicts the blade’s effect, and while blade design can affect vibration, that isn’t the main advantage being highlighted here.
