  Chapter 5: Aerodynamics of Flight › Ground Effect

  Figure 5-16. Ground effect changes airflow. Ground effect also alters the thrust required versus velocity. Since induced drag predominates at low speeds, the reduction of induced drag due to ground effect will cause a significant reduction of thrust required ... wingtip vortices, there may be a change in position (installation) error of the airspeed system associated with ground effect. In the majority of cases, ground effect causes an increase in the local pressure at the static source and produces…

  item that alters the landing speed or deceleration rate during the landing roll affects the landing distance. The effect of gross weight on landing distance is one of the principal items determining the landing distance. One effect of an increased ... speed is required to support the aircraft at the landing AOA and lift coefficient. For an example of the effect of a change in gross weight, a 21 percent increase in landing weight requires a ten percent increase in landing…

Others are external factors outside of the instructor’s control that prevent ... process or activity from being carried out properly. These factors may include physiological, environmental, and psychological elements. To communicate effectively, the instructor should consider the effects of these factors and mitigate them where possible…

  Chapter 2: Aerodynamics of Flight › Translational Thrust › Transverse Flow Effect

  Transverse Flow Effect As the helicopter accelerates in forward flight, induced flow drops to near zero at the forward disk area and increases at the aft disk area. These differences in lift between the fore and aft portions ... rotor disk are called transverse flow effect. [Figure 2-41] This increases the AOA at the front disk area causing the rotor blade to flap up and reduces AOA at the aft disk area causing the rotor blade to flap…

The ailerons are generally close ... control force. Provided the pilot is able to adjust for the unusual forces, the ailerons may still be substantially effective when they are deflected. The other is that ailerons may be affected in a substantial degradation in control effectiveness, although…
