33.4.6.2 AOA Calibration Procedure
Perform the procedure steps in this section including, Minimum Visible AOA Calibration
, Caution Alert
AOA Calibration, Stall Warning AOA Calibration, and Approach Target AOA Calibration (Optional).
Any of the calibration procedures can be repeated to fine-tune the behavior of the AOA gauge and audio
alerting.
For best results, perform all AOA calibration in smooth air. Turbulence or rough air can
affect the calibration.
The calibration values displayed for the AOA calibration points are proportional to actual
AOA (the greater the calibration value, the greater the AOA) but are not otherwise
representative of any specific unit of measure.
For the calibration to be valid:
• The stall warning AOA calibration value (resultant from the calibration procedure) must be greater
than the minimum visible AOA calibration value (see Figure 33-25).
• The caution alert AOA calibration value (resultant from the calibration procedure) must be greater
than the minimum visible AOA calibration value and less than the stall warning AOA calibration
value (see Figure 33-25).
