Minimum Visible AOA Calibration
This procedure sets the AOA value for the bottom of the AOA gauge green arc (Figure 34-10), which is
also the AOA value at which the gauge will first appear on the PFD. Perform this calibration while flying
the aircraft at an AOA somewhat higher than a normal cruise flight (1.5 x stall speed is suggested) to avoid
nuisance frequent appearances of the AOA gauge.
1. Use the Touch Panel or a Move Selector Knob to select the Calibrate button in the Minimum
Visible AOA Calibration field.
2. Follow the onscreen instructions, then press the Start button to begin the calibration.
3. Follow the onscreen instructions, then press the Done button when finished.
