  Chapter 11: Aircraft Performance › Performance › Straight-and-Level Flight

  Straight-and-Level Flight All of the principal components of flight performance involve steady-state flight conditions and equilibrium of the aircraft. For the aircraft to remain in steady, level flight, equilibrium must be obtained by a lift equal ... aircraft weight and a powerplant thrust equal to the aircraft drag. Thus, the aircraft drag defines the thrust required to maintain steady, level flight. As presented in Chapter 4, Aerodynamics of Flight, all parts of an aircraft contribute…

  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 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…

  Figure 5-36. Changes in lift during climb entry. The thrust required for a stabilized climb equals drag plus a percentage of weight dependent on the angle of climb. For example, a 10° climb would require thrust to equal drag ... plus 17 percent of weight. To climb straight up would require thrust to equal all of weight and drag. Therefore, the angle of climb for climb performance is dependent on the amount of excess thrust available to overcome a portion…

  Chapter 5: Aerodynamics of Flight › Thrust

  Figure 5-2. Force vectors during a stabilized climb. Likewise, if the engine power is increased, thrust becomes greater than drag and the airspeed increases. As long as the thrust continues to be greater than the drag, the aircraft continues ... accelerate. When drag equals thrust, the aircraft flies at a constant airspeed. Straight-and-level flight may be sustained at a wide range of speeds. The pilot coordinates AOA and thrust in all speed regimes if the aircraft…

  Chapter 3: Basic Flight Maneuvers › Straight-and-Level Flight › Straight Flight

  Straight Flight Maintaining a constant direction or heading is accomplished by visually checking the relationship of the airplane’s wingtips to the natural horizon. Depending on whether the airplane is a high wing or low wing, both wingtips should ... level and equally above or below the natural horizon. Any necessary bank corrections are made with the pilot’s coordinated use of ailerons and rudder. [Figure 3-7] The pilot should understand that anytime the wings are banked, the airplane…
