  • Chapter 3: Identifying Hazards & Associated Risks › Why Hazards Result in Aviation Accidents › Understanding the Risks Posed by Hazards

    prerogative to question authority if it seems to be in error. This is the attitude of people who frequently feel the need to do something—anything—immediately. They do not stop to think about what they are about ... never to them. They know accidents can happen, and they know that anyone can be affected. They never really feel or believe that they will be personally involved. Pilots who think this way are more likely to take chances…

  • Chapter 5: Aerodynamics of Flight › Load Factors › Load Factors and Stalling Speeds

    factors produced in different aircraft. In most cases, load factors can be judged by the experienced pilot from the feel of seat pressure. Load factors can also be measured by an instrument called an “accelerometer,” but this instrument ... common in general aviation training aircraft. The development of the ability to judge load factors from the feel of their effect on the body is important. A knowledge of these principles is essential to the development of the ability…

Pilots who think this way are more likely to take chances and increase ... well, the pilot is apt to think that it is good luck. When things go badly, the pilot may feel that someone is out to get them or attribute it to bad luck. The pilot will leave the action…

    still an effective demonstration because it illustrates the inability to detect bank or roll. Skid, slip, and uncoordinated turns feel similar. Pilots feel they are being forced sideways in their seat. Figure 17-6. Sensations from centrifugal force. There…

  • Chapter 6: Flight Controls › Flight Control Systems › Primary Flight Controls

    Flight Controls Aircraft control systems are carefully designed to provide adequate responsiveness to control inputs while allowing a natural feel. At low airspeeds, the controls usually feel soft and sluggish, and the aircraft responds slowly to control applications. At higher…

  • Chapter 3: Basic Flight Maneuvers › Effect and Use of Flight Controls › Feel of the Airplane

    forced downward into the seat due to the resultant load factor. The increased G force of a turn feels the same as the pull up from a dive, and the decreased G force from leveling out feels the same ... lowering the nose out of a climb. Sources of actual “feel” are very important to the pilot. This actual feel is the result of acceleration, which is simply how fast velocity is changing. Acceleration describes the rate of change…
