  Chapter 6: Flight Controls › Flight Control Systems › Primary Flight Controls

  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 ... 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 to control inputs while allowing a natural feel. At low airspeeds…

  Chapter 5: Aerodynamics of Flight › Boundary Layer Separation › High Speed Flight Controls

  High Speed Flight Controls On high-speed aircraft, flight controls are divided into primary flight controls and secondary or auxiliary flight controls. The primary flight controls maneuver the aircraft about the pitch, roll, and yaw axes. They include the ailerons…

  Chapter 6: Flight Controls › Flight Control Systems › Spoilers

  flight deck controls and small hinged devices attached to the trailing edge of one or more of the primary flight control surfaces. Designed to help minimize a pilot’s workload, trim systems aerodynamically assist movement and position of the flight…

  aircraft’s electrical power system is used to operate the flight instruments, essential systems, such as anti-icing, and passenger services, such as cabin lighting. The flight controls are the devices and systems that govern the attitude of an aircraft ... result, the flight path followed by the aircraft. In the case of many conventional airplanes, the primary flight controls utilize hinged, trailingedge surfaces called elevators for pitch, ailerons for roll, and the rudder for yaw. These surfaces are operated…

  Chapter 6: Flight Controls › Autopilot

  aerodynamic characteristics vary greatly between aircraft, it is essential that a pilot become familiar with the primary and secondary flight control systems of the aircraft being flown. The primary source of this information is the AFM or the POH. Various ... websites can also be a valuable source of additional information. Figure 6-24.
