  moment travels forward faster than the inside wing and, as a consequence, its lift becomes greater. This produces an overbanking tendency which, if not corrected by the pilot, results in the bank angle becoming steeper and steeper. At the same…

  Chapter 5: Aerodynamics of Flight › Aircraft Design Characteristics › Dynamic Stability

  Static Stability Static stability refers to the initial tendency, or direction of movement, back to equilibrium. In aviation, it refers to the aircraft’s initial response when disturbed from a given pitch, yaw, or bank. • Positive static stability—the initial ... tendency of the aircraft to return to the original state of equilibrium after being disturbed. [Figure 5-21] • Neutral static stability—the initial tendency of the aircraft to remain in a new condition after its equilibrium has been disturbed. [Figure…

  individual experience and training. Operational Pitfalls Although more experienced pilots are likely to make more automatic decisions, there are tendencies or operational pitfalls that come with the development of pilot experience. These are classic behavioral traps into which pilots have ... piloting skills. All experienced pilots have fallen prey to, or have been tempted by, one or more of these tendencies in their flying careers. These dangerous tendencies or behavior patterns, which must be identified and eliminated, include the operational pitfalls…

(3) In an airplane, the tendency of the aircraft to turn (roll) in the opposite direction of rotation of the engine and propeller. (4) In helicopters ... with a single, main rotor system, the tendency of the helicopter to turn in the opposite direction of the main rotor rotation. Torquemeter.

  Chapter 17: Aeromedical Factors › Flicker Vertigo › Night Landing Illusions

  Night Landing Illusions Landing illusions occur in many forms. Above featureless terrain at night, there is a natural tendency to fly a lowerthan-normal approach. Elements that cause any type of visual obscurities, such as rain, haze, or a dark ... Bright lights, steep surrounding terrain, and a wide runway can produce the illusion of being too low with a tendency to fly a higher-than-normal approach. A set of regularly spaced lights along a road or highway can appear…
