- Chapter 5: Aerodynamics of Flight › Load Factors › Load Factors and Flight Maneuvers
Spins Load Factors and Flight Maneuvers Critical load factors apply to all flight maneuvers except unaccelerated straight flight where a load factor of 1 G is always present. Certain maneuvers considered in this section are known to involve relatively high ... load factors. Full application of pitch, roll, or yaw controls should be confined to speeds below the maneuvering speed. Avoid rapid and large alternating control inputs, especially in combination with large changes in pitch, roll, or yaw (e.g., large sideslip…
- Chapter 5: Aerodynamics of Flight › Aircraft Design Characteristics › Lateral Stability (Rolling)
There are four main design factors that make an aircraft laterally stable: dihedral, sweepback, keel effect, and weight distribution. Dihedral Some aircraft are designed so that the outer tips of the wings are higher than the wing roots. The upward ... angle thus formed by the wings is called dihedral. [Figure 5-28] When a gust causes a roll, a sideslip will result. This sideslip causes the relative wind affecting the entire airplane to be from the direction of the slip…
- Chapter 9: Techniques of Flight Instruction › Postflight Evaluation › First Solo Flight
First Solo Flight During the learner’s first solo flight, the instructor needs to be present to assist in answering questions or resolving any issues that arise during the flight. To ensure the solo flight is a positive, confidence-building ... experience for the learner, the flight instructor needs to consider time of day when scheduling the flight. Time of day is a factor in traffic congestion, possible winds, sun angles, and reflection. If possible, the flight instructor needs access…
- 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
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 › Aerodynamic Forces in Flight Maneuvers › Forces in Climbs
Normal, slipping, and skidding turns at a constant altitude. If the climb is entered with no change in power setting, the airspeed gradually diminishes because the thrust required to maintain a given airspeed in level flight is insufficient to maintain ... same airspeed in a climb. When the flight path is inclined upward, a component of the aircraft’s weight acts in the same direction as, and parallel to, the total drag of the aircraft, thereby increasing the total effective drag…
