  • Chapter 5: Aerodynamics of Flight › Ground Effect

    aircraft leaving ground effect after takeoff encounters just the reverse of an aircraft entering ground effect during landing. The aircraft leaving ground effect will: • Require an increase in AOA to maintain the same CL • Experience an increase in induced drag ... nose-up change in moment • Experience a reduction in static source pressure and increase in indicated airspeed Ground effect must be considered during takeoffs and landings. For example, if a pilot fails to understand the relationship between the aircraft…

  • Chapter 17: Aeromedical Factors › Ground Lighting Illusions › How To Prevent Landing Errors Due to Optical Illusions

    Maintain optimum proficiency in landing procedures. In addition to the sensory illusions due to misleading inputs to the vestibular system, a pilot may also encounter various visual illusions during flight. Illusions rank among the most common factors cited as contributing ... fatal aviation accidents. Sloping cloud formations, an obscured horizon, a dark scene spread with ground lights and stars, and certain geometric patterns of ground light can create illusions of not being aligned correctly with the actual horizon. Various surface features…

  • Chapter 14: Airport Operations › Collision Avoidance › Runway Incursion Avoidance

    prevent ground deviations, stay alert during ground operations. Pilot deviations can and frequently do occur on the ground. Many strategies and tactics pilots use to avoid airborne deviations also work on the ground. Pilots should also remain vigilant about vehicle/pedestrian ... entering or moving on the runway movement area without authorization from air traffic control. In serious instances, any ground deviation (PD or VPD) can result in a runway incursion. Best practices in preventing ground deviations can be found…

  • Chapter 14: Airport Operations › Collision Avoidance › Pilot Deviations (PDs)

    temporary flight restriction (TFR). Take a few minutes prior to each flight to plan accordingly. • Talk and squawk—Proper communication with ATC has its benefits. Flight following often makes the controller’s job easier because they can better integrate ... trying to avoid could result in a pilot deviation because ATC radar may show you within the restricted airspace. Ground deviations (also called surface deviations) include taxiing, taking off, or landing without clearance, deviating from an assigned taxi route…

  • Chapter 11: Aircraft Performance › Performance Charts › Sample Problem 11

    Cruise performance graph. Landing Charts Landing performance is affected by variables similar to those affecting takeoff performance. It is necessary to compensate for differences in density altitude, weight of the airplane, and headwinds. Like takeoff performance charts, landing distance information ... weight must be recalculated to compensate for the fuel that was used during the flight. Figure 10-31. Crosswind component chart. Sample Problem 11 Refer to Figure 10-32. This example makes use of a landing distance table. Notice that…

  • Chapter 9: Basic Flight Maneuvers › Ground Reference Maneuvers › Technique

    into the wind in order to maintain the proper ground track. Keep in mind that in order to maintain proper ground track the helicopter may have to be flown almost sideways depending on the amount of wind. The forward cyclic ... again appears to be one-fourth to one-half mile away. While on the crosswind leg, the wind correction should be adjusted, as necessary, to maintain a uniform distance from the field boundary (position…
