  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…

  This causes a pressure differential that is indicated on the instrument needle as a climb or descent. When the pressure differential stabilizes at a definite ratio, the needle indicates the rate of altitude change. Figure 8-5. Vertical speed indicator ... displays two different types of information: Trend information shows an immediate indication of an increase or decrease in the aircraft’s rate of climb or descent. • Rate information shows a stabilized rate of change in altitude. The trend information…

  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…

  Slip/Skid Indicator The slip/skid indicator is the horizontal line below the roll pointer. [Figure 8-12] Like a ball in a turn-and-slip indicator, a bar width off center is equal to one ball width displacement. Turn Rate Indicator ... turn rate indicator, illustrated in Figure 8-12, is typically found directly above the rotating compass card. Tick marks to the left and right of the lubber line denote the turn (standard-rate versus half standard-rate). Typically denoted…

  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 an AOA indicator, the AOA is “invisible” to pilots. These devices measure several parameters ... fuel savings. This equates to a lower operating cost to the pilot. Figure 5-41. A variety of AOA indicators…

  calibrated to permit adjustments in precise increments. [Figure 3-20] The instrument for attitude display is the attitude indicator. The control instruments do not indicate aircraft speed or altitude. In order to determine these variables and others, a pilot must ... reference the performance instruments. Navigation Instruments The navigation instruments indicate the position of the aircraft in relation to a selected navigation facility or fix. This group of instruments includes various types of course indicators, range indicators, glideslope indicators, and bearing…
