Chapter 11: Helicopter Emergencies and Hazards › Low Rotor RPM and Rotor Stall
Consequently, early recognition of the low rotor rpm condition and proper recovery technique is imperative. Low rotor rpm can occur during power-off and power-on operations. During power-off flight, a low rpm situation can be caused ... occur with a heavily loaded helicopter taking off from a confined area. Other causes of a power-on low rotor rpm condition include the pilot rolling the throttle the wrong way in helicopters not equipped with a governor…

flapping is minimal, perhaps 2° under usual flight conditions. Flapping angles increase slightly with high forward speeds, at low rotor rpm, at high-density altitudes, at high gross weights, and when encountering turbulence. Maneuvering the aircraft in a sideslip…

Chapter 11: Helicopter Emergencies and Hazards › Autorotation › RPM Control
RPM Control Rotor rpm in low inertia rotor systems has been studied in simulator flight evaluations which indicate that the simultaneous application of aft cyclic, down collective, and alignment with the relative wind (trim) at a wide range of airspeeds ... basic discussion of the aerodynamics and control inputs for single rotor 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…
