  manner as those mentioned for an excess weight condition. It is vital to comply with weight and balance limits established for all aircraft. Operating above the maximum weight limitation compromises the structural integrity of the aircraft and can adversely affect ... performance. Stability and control are also affected by improper balance. Stability Loading in a nose-heavy condition causes problems in controlling and raising the nose, especially during takeoff and landing. Loading in a tail heavy condition has a serious effect…

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

  Neutral dynamic 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 ... quality of the aircraft’s response to the pilot’s control application when maneuvering the aircraft, regardless of its stability characteristics. Longitudinal Stability (Pitching) In designing an aircraft, a great deal of effort is spent in developing the desired degree…

  Maintaining trim drag to a minimum These requirements are met by the use of a variable incidence horizontal stabilizer. Large trim changes on a fixed-tail aircraft require large elevator deflections. At these large deflections, little further elevator movement remains ... same direction. A variable incidence horizontal stabilizer is designed to take out the trim changes. The stabilizer is larger than the elevator, and consequently does not need to be moved through as large an angle. This leaves the elevator streamlining…

  descend at the same airspeed as used in straight-and-level flight, the power must be reduced as the descent is entered. Entering the descent, the component of weight acting forward along the flight path increases as the angle ... descent increases and, conversely, when leveling off, the component of weight acting along the flight path decreases as the angle of descent decreases. Stalls An aircraft stall results from a rapid decrease in lift caused by the separation of airflow…
