  • Chapter 17: Aeromedical Factors › Health and Physiological Factors Affecting Pilot Performance › Diving or Rolling Beyond the Vertical Plane

    toward a 30° or 40° angle of bank. As this is in progress, the pilot tilts his or her head forward, looks to the right or left, then immediately returns his or her head to an upright position. The instructor ... pilot should time the maneuver so the roll is stopped as the pilot returns his or her head upright. An intense disorientation is usually produced by this maneuver, and the pilot experiences the sensation of falling downward into the direction…

  • Chapter 8: Flight Instruments › Instrument Check › Heading Indicator

    attitude indicator corresponds to the relation of the aircraft to the real horizon. The operation of the heading indicator depends upon the principle of rigidity in space. The rotor turns in a vertical plane and fixed to the rotor ... instrument case and the aircraft revolve around the vertical axis of the gyro, the card provides clear and accurate heading information. Because of precession caused by friction, the heading indicator creeps or drifts from its set position. Among other factors…

  • Chapter 8: Flight Instruments › Electronic Flight Display (EFD) › Heading Indicator

    Heading Indicator The heading indicator is located below the artificial horizon and is normally modeled after a Horizontal Situation Indicator (HSI). [Figure 8-12] As in the case of the attitude indicator, the heading indicator receives its information from…

  • Chapter 8: Flight Instruments › Instrument Check › Remote Indicating Compass

    Figure 8-28. The current in each of the three pickup coils changes with the heading of the aircraft. There are a number of designs of the remote indicating compass; therefore, only the basic features of the system are covered ... driven by an automatic direction finder (ADF) and a very high frequency (VHF) omni-directional radio range (VOR). Heading indicators that do not have this automatic northseeking capability are called “free” gyros and require periodic adjustment. It is important…

  • Chapter 13: Transition to Multiengine Airplanes › Engine Inoperative Flight Principles › VMC Demo Stall Avoidance

    same. [Figure 13-14] Should a stall occur while the airplane is under asymmetrical power, a spin entry is likely. The yawing moment induced from asymmetrical thrust is little different from that induced by full rudder in an intentional spin ... controlled flight might be quite sudden, with strong yawing and rolling tendencies to the inverted orientation and a spin entry. Therefore, during a VMC demonstration, if there are any symptoms of an impending stall such as a stall warning light…

  • Chapter 10: Performance Maneuvers › Steep Spiral

    throttle, the pitch attitude should be adjusted to maintain a constant airspeed and, preferably, this should be done when headed into the wind. Maintaining a constant airspeed throughout the maneuver is an important skill for a pilot to develop. This ... pilot should execute at least three turns and roll out toward a definite object or on a specific heading. To make the exercise more challenging, the pilot rolls out on a heading perpendicular to or directly into the wind rather…
