Viser "Angle of attack"

For en lengre innføring i temaet for "tubeliners", er denne fin. 

 

Fra FCOM 

1. Digital AOA Readout (white)

2. Stick Shaker Indicator (red)

   Indicates point at which stick shaker activation occurs for existing flight conditions. Blank if AOA signal is invalid.

3. Analog Needle (white)

   Indicates analog AOA value.

   • needle travel is limited to a range of -6 degrees and +21 degrees
   • fixed at 0.0 degrees when on the ground and ground speed is less than 80 knots.

4. Approach Reference Band (green)

   Indicates appropriate range of approach AOA for a Vref(xx) + 5 approach.

   • displayed when in normal or single engine landing flaps (15, 30, 40)
   • moves with flap position
