- Chapter 6: Flight Controls › Flight Control Systems › Primary Flight Controls
Flight Control Systems Flight Controls Aircraft flight control systems consist of primary and secondary systems. The ailerons, elevator (or stabilator), and rudder constitute the primary control system and are required to control an aircraft safely during flight. Wing flaps, leading ... edge devices, spoilers, and trim systems constitute the secondary control system and improve the performance characteristics of the airplane or relieve the pilot of excessive control forces. Primary Flight Controls Aircraft control systems are carefully designed to provide adequate responsiveness…
- Chapter 1: Introduction to the Helicopter › Controlling Flight › Throttle
Throttle Helicopter rotors are designed to operate at a specific rpm. Figure 1-11. The throttle control mounted at the end of the collective control. The throttle controls the power produced by the engine, which is connected to the rotor ... transmission. The purpose of the throttle is to maintain enough engine power to keep the rotor rpm within allowable limits to produce enough lift for flight. In single-engine helicopters, if so equipped, the throttle control is typically a twist…

aircraft to move down and the nose to move up. In spite of the opposing directional movement of the trim tab and the elevator, control of trim is natural to a pilot. If the pilot needs to exert constant back ... pressure on a control column, the need for nose-up trim is indicated. The normal trim procedure is to continue trimming until the aircraft is balanced and the nose-heavy condition is no longer apparent. Pilots normally establish the desired…
- 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
Chapter Summary This chapter introduced the basics of aerodynamic fundamentals and theory and how they relate to flying a helicopter. This chapter also explained how aerodynamics affect helicopter flight and how important it is for pilots to understand aerodynamic principles ... prepared to react to these effects. For additional information on aerodynamics, refer to the aerodynamics of flight portion of the Pilot’s Handbook of Aeronautical Knowledge. Figure 2-48. Force vectors in vertical autorotation descent. Figure 2-49. Blade regions…

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…
