- 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…

with low inertia rotor disks settle immediately. Keep a level attitude and ensure a vertical descent with cyclic control while maintaining heading with the pedals. Any lateral movement must be avoided to prevent dynamic rollover. As rotor rpm decays, cyclic ... idle and off in which the idle release button snaps into, prevent accidental throttle off. Helicopters with high-inertia rotor disks settle more slowly after the throttle is closed. In this case, when the helicopter has settled to approximately…

nose-low. This situation requires the use of excessive power to initiate a climb. 2. Using excessive power combined with a level attitude, which causes a vertical climb, unless needed for obstructions and landing considerations. 3. Application of the collective ... that is too abrupt when departing the surface, causing rpm and heading control errors. Crosswind Considerations During Takeoffs If the takeoff is made during crosswind conditions, the helicopter is flown in a slip during the early stages of the maneuver…
