  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…

  Chapter 2: Aeronautical Decision-Making › Decision-Making in a Dynamic Environment › Operational Pitfalls

  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…

  Chapter 5: Aerodynamics of Flight › Directional Stability (Yawing) › Spiral Instability

  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 time ... spiral dive. Usually the rate of divergence in the spiral motion is so gradual the pilot can control the tendency without any difficulty. Many aircraft are affected to some degree by this characteristic, although they may be inherently stable…

  Chapter 5: Aerodynamics of Flight › Aircraft Design Characteristics › Longitudinal Stability (Pitching)

  stability—once displaced, the displaced object neither decreases nor increases in amplitude. A worn automobile shock absorber exhibits this tendency. • Negative dynamic stability—over time, the motion of the displaced object increases and becomes more divergent. Stability in an aircraft ... pitching motion as the aircraft’s nose moves up and down in flight. A longitudinally unstable aircraft has a tendency to dive or climb progressively into a very steep dive or climb, or even a stall. Thus, an aircraft with…

  resistance to turning or twisting. (2) Forces that produce a twisting or rotating motion. (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.
