  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 5: Aerodynamics of Flight › Angle of Attack Indicators

  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…

  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…

  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…

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

  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 here. Instrument pilots must become familiar with the characteristics ... 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…

  Figure 5-9. A conceptual representation of an AOA indicator. It is important to become familiar with the equipment installed in a specific airplane. Installation of AOA indicators not required by type certification in GA airplanes has been streamlined ... updated information on this, please reference the FAA website at www.faa.gov. If airplane equipment includes an angle of attack indicator, the pilot should know how the particular device determines AOA, what the display indicates, and the appropriate response…
