Minimum Visible AOA Calibration
This procedure sets the AOA value for the bottom of the AOA gauge green arc (Figure 31-25), 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 FMS Joystick to select the Calibrated Minimum Visible AOA calibration field, then press
the Calibrate softkey .
2. Follow the onscreen instructions, then press the Start softkey to begin the calibration.
