  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 9: Techniques of Flight Instruction › Positive Exchange of Flight Controls › Procedure

  Procedure During flight training, there should always be a clear understanding between learners and flight instructors about who has control of the aircraft. The preflight briefing should include procedures for the exchange of flight controls. A positive three-step process ... exchange of flight controls between pilots is a proven procedure and one that is strongly recommended. When an instructor is teaching a maneuver to a learner, the instructor normally demonstrates the maneuver first, then has the learner follow along…

  Chapter 6: Flight Controls

  Chapter Summary In order to sustain an aircraft in flight, a pilot must understand how thrust, drag, lift, and weight act on the aircraft. By understanding the aerodynamics of flight, how design, weight, load factors, and gravity affect an aircraft ... during flight maneuvers from stalls to high speed flight, the pilot learns how to control the balance between these forces. For information on stall speeds, load factors, and other important aircraft data, always consult the AFM/POH for specific information pertaining…

  Chapter 5: Aerodynamics of Flight › Axes of an Aircraft

  Whenever an aircraft changes its flight attitude or position in flight, it rotates about one or more of the three axes. [Figure 5-18] The aircraft’s motion about its longitudinal axis resembles the roll of a ship from side ... side. In fact, the names used to describe the motion about an aircraft’s three axes were originally nautical terms. They have been adapted to aeronautical terminology due to the similarity of motion of aircraft and seagoing ships. The motion…

  Chapter 11: Helicopter Emergencies and Hazards › Dynamic Rollover

  Dynamic Rollover A helicopter is susceptible to a lateral rolling tendency, called dynamic rollover, when it is in contact with the surface during takeoffs or landings. For dynamic rollover to occur, some factor must first cause the helicopter to roll ... pivot around a skid or landing gear wheel, until its critical rollover angle is reached. The angle at which dynamic rollover occurs will vary based on helicopter type. Then, beyond this point, main rotor thrust continues the roll and recovery…

  Figure 1-5. Fuel in the tanks of a swept-wing airplane affects both lateral and longitudinal balance. As fuel is used from an outboard tank, the CG shifts forward. The fixed-wing airplane has movable controls that alter lift ... airfoil surfaces to vary pitch, roll, and yaw. In turn, these changes in lift affect the characteristics of the flight parameters. Weight normally decreases in flight due to fuel consumption, and the airplane CG changes with this weight reduction…
