  • 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 ... information to the AHRS unit and then out to the PFD. Figure 8-13. Multi-function display (MFD). Turn Indicator The turn indicator takes a slightly different form than the traditional instrumentation. A sliding bar moves left and right below…

  • Chapter 8: Flight Instruments › Gyroscopic Flight Instruments › Turn-and-Slip Indicator

    Turn Indicators Aircraft use two types of turn indicators: turn-and-slip indicators and turn coordinators. Because of the way the gyro is mounted, the turn-and-slip indicator shows only the rate of turn in degrees per second ... mounted at an angle, or canted, so it can initially show roll rate. When the roll stabilizes, it indicates rate of turn. Both instruments indicate turn direction and quality (coordination), and also serve as a backup source of bank information…

  • Chapter 5: Aerodynamics of Flight › Angle of Attack Indicators

    Figure 5-41. A variety of AOA indicators. Just as training is required for any system on an aircraft, AOA indicators have training considerations also. A more comprehensive understanding of AOA in general should be the goal of this training ... along with the specific operating characteristics and limitations of the installed AOA indicator. Ground and flight instructors should make every attempt to receive training from an instructor knowledgeable about AOA indicators prior to giving instruction pertaining to or in airplanes…

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

    operating in instrument meteorological conditions or confuse a pilot during an unusual attitude recovery. A number of modern attitude indicators do not have this problem. Every pilot should be able to interpret the banking scale illustrated in Figure ... Most banking scale indicators on the top of the instrument move in the same direction from that in which the aircraft is actually banked. Some other models move in the opposite direction from that in which the aircraft is actually…

  • Chapter 8: Flight Instruments › Angle of Attack Indicators

    Angle of Attack Indicators The purpose of an AOA indicator is to give the pilot better situational awareness pertaining to the aerodynamic health of the airfoil. This can also be referred to as stall margin awareness. More simply explained ... This critical AOA does not change with: • Weight • Bank Angle • Temperature • Density Altitude • Center of Gravity An AOA indicator can have several benefits when installed in General Aviation aircraft, not the least of which is increased situational awareness. Without…

  • Chapter 7, Section II: Airplane Basic Flight Maneuvers › Straight-and-Level Flight

    specific pitch attitude for level flight. At slow cruise speeds, the level flight attitude is nose-high with indications as in Figure 7-47; at fast cruise speeds, the level flight attitude is nose-low. [Figure 7-48] Figure ... shows the indications for the attitude at normal cruise speeds. Figure 7-47. Pitch attitude and airspeed in level flight, slow cruise speed. Figure 7-49. Various pitch attitudes (right), aircraft shown in level flight. The instruments that directly…
