When the collective is raised, the opposite antitorque pedal used in powered flight will be needed due to the friction within the transmission/drive train. Touch down in a level flight attitude. Control response with increased pitch angles will be slightly ... raise the tail. This can result in a severe nose tuck which is quickly corrected with right pedal application. A power recovery can be made during training in lieu of a full touchdown landing. Refer to the section on power…

airspeed of less than 10 knots. When the aircraft begins to shudder, the application of additional up collective increases the vibration and sink rate. As the power is increased, the rate of sink of the aircraft in the column…

keep the helicopter from drifting. Control pressures and direction of application change continuously throughout the turn. The most dramatic change is the pedal pressure (and corresponding power requirement) necessary to control the rate of turn as the helicopter moves through…
- Chapter 11: Helicopter Emergencies and Hazards › Autorotation › RPM Control
wide range of airspeeds, including cruise airspeeds, is critical for all operations during the entry of an autorotation. The applicable Rotorcraft Flight Manual (RFM) should be consulted to determine the appropriate procedure(s) for safely entering an autorotation. This ... systems is in order here. Helicopter pilots must understand the use of the collective for rotor rpm control during power off autorotations in a turn. Upward movement of the collective reduces the rpm and downward movement increases the rpm. Cyclic…

forward cyclic (especially when immediately following aft cyclic application), torque increases and rotor speed decreases. • Always leave a way out. • Know where the winds are. • Engine failures can occur during power changes and cruise flight. One possible cause of engine…

(3) The takeoff, flight, and landing procedures such as the approximate trim setting, method of power application, maximum power, and speed must be established. The airplane must be satisfactorily controllable during the entire takeoff run when operated according…
