- Chapter 11: Helicopter Emergencies and Hazards › Recovery Technique (Uncontrolled Right Yaw) › Governor or Fuel Control Failure
Governor or Fuel Control Failure Governors and fuel control units automatically adjust engine power to maintain rotor rpm when the collective pitch is changed. If the governor or fuel control unit fails, any change in collective pitch requires manual adjustment ... engine being commanded to put out too much power. If the rpm cannot be reduced and controlled with the throttle, close the throttle and enter an autorotation. If the failure is on the low side, the engine output is allowed…
- Chapter 11: Helicopter Emergencies and Hazards › Autorotation › RPM Control
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, 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 is vitally important since the procedure…
- Chapter 3: Helicopter Flight Controls › Cyclic Pitch Control
Cyclic Pitch Control The cyclic pitch control (or simply “cyclic”) is usually projected upward from the cockpit floor, between the pilot’s legs or between the two pilot seats in some models. [Figure 3-4] This primary flight control allows ... helicopter in any direction of travel: forward, rearward, left, and right. As discussed in Chapter 2, Aerodynamics of Flight, the total lift force is always perpendicular to the tip-path plane of the main rotor. The purpose of the cyclic…

addition, in some large and fast aircraft, controls are boosted by hydraulically or electrically actuated systems. In both the fly-by-wire and boosted controls, the feel of the control reaction is fed back to the pilot by simulated means ... Current research at the National Aeronautics and Space Administration (NASA) Dryden Flight Research Center involves Intelligent Flight Control Systems (IFCS). The goal of this project is to develop an adaptive neural network-based flight control system. Applied directly to flight…
- Chapter 3: Helicopter Flight Controls › Collective Pitch Control
Collective Pitch Control The collective pitch control (or simply “collective” or “thrust lever”) is located on the left side of the pilot’s seat and is operated with the left hand. The collective is used to make changes ... main rotor blades and does this simultaneously, or collectively, as the name implies. As the collective pitch control is raised, there is a simultaneous and equal increase in pitch angle of all main rotor blades; as it is lowered, there…
- Chapter 2: Aerodynamics of Flight › Hovering Flight
Hovering Flight Hovering is the most challenging part of flying a helicopter. This is because a helicopter generates its own gusty air while in a hover, which acts against the fuselage and flight control surfaces. The end result is constant ... control inputs and corrections by the pilot to keep the helicopter where it is required to be. Despite the complexity of the task, the control inputs in a hover are simple. The cyclic is used to eliminate drift…
