  • 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 6: Threat and Error Management › Causes of Errors › Physiological Effects

    Physiological Effects Some of the items listed on the I’m Safe checklist (illness, medication, stress, alcohol, fatigue) have the potential to cause pilot errors. For example, it may become difficult or impossible for a stressed or fatigued pilot ... pilot’s individual sense of vision combined with all the visual signals received at the same time. Psychological Effects Psychological effects include stress, emotion, expectation bias, and the effects of personality. Stress & Emotion…

  • Chapter 10: Weight and Balance › Effects of Weight

    Longer landing roll • Excessive weight on the nose wheel or tail wheel The pilot must be knowledgeable about the effect of weight on the performance of the particular aircraft being flown. Preflight planning should include a check of performance charts ... fuel is used, an aircraft becomes lighter and performance is improved. Changes of fixed equipment have a major effect upon the weight of an aircraft. The installation of extra radios or instruments, as well as repairs or modifications, may also…

  • Chapter 8: Flight Instruments › Effect of Nonstandard Pressure and Temperature

    Effect of Nonstandard Pressure and Temperature It is easy to maintain a consistent height above ground if the barometric pressure and temperature remain constant, but this is rarely the case. The pressure and temperature can change between takeoff and landing ... important to frequently obtain current altimeter settings en route to ensure terrain and obstruction clearance. Figure 8-3. Effects of nonstandard temperature on an altimeter. Many altimeters do not have an accurate means of being adjusted for barometric pressures…

  • Chapter 17: Aeromedical Factors › Hydraulic Fluid › Drugs

    multiple medications are being taken at the same time, the adverse effects can be even more pronounced. Another important consideration is that the medical condition for which a medication is prescribed may itself be disqualifying. The FAA will consider ... Some of the most commonly used OTC drugs, antihistamines and decongestants, have the potential to cause noticeable adverse side effects, including drowsiness and cognitive deficits. The symptoms associated with common upper respiratory infections, including the common cold, often suppress…

  • Chapter 11: Aircraft Performance › Takeoff and Landing Performance › Takeoff Performance

    Figure 11-19 illustrates the general effect of wind by the percent change in takeoff or landing distance as a function of the ratio of wind velocity to takeoff or landing speed. The effect of proper takeoff speed is especially ... initial ROC. In some cases, an excessive AOA may not allow the aircraft to climb out of ground effect. On the other hand, an excessive airspeed at takeoff may improve the initial ROC and “feel” of the aircraft but produces…
