Pedal feedback is exacerbated at which setting and may require up to 70 pounds of force to hold heading or add additional right pedal?

Pedal feedback is exacerbated at which setting and may require up to 70 pounds of force to hold heading or add additional right pedal?

• A. Low power settings
• B. High power settings
• C. Neutral
• D. High airspeed

Answer: (B)

Pedal feedback increases with power because the anti-torque demand from the tail rotor grows as engine power increases. When you raise power, the main rotor torque rises, and the tail rotor must produce more thrust to counteract that torque and keep the nose from yawing. That stronger tail-rotor effort is transmitted back through the control system, making the pedals feel stiffer and can require as much as about 70 pounds of force to hold heading or to apply additional right pedal. So the setting that produces the most pedal feedback is high power settings. Low power reduces the tail-rotor load, and while high airspeed or crosswinds can affect yaw, the described heavy pedal feel is tied primarily to the increased anti-torque demand at high power.
