Garmin AOA System AOA System Owner’s Manual - Page 15

AOA System The Approach AOA should be calibrated (refer to Appendix C of the AOA System Installation Manual) at an acceptable margin above CLmax to fly an approach. As a starting point, use the aircraft manual to determine the stall speed of the aircraft at the actual gross weight in the landing configuration. Multiply the calibrated airspeed by 1.3, then convert from calibrated airspeed to indicated airspeed (if necessary). Once the AOA angles have been calibrated, they will be accurate in the calibrated flap configuration, at any gross weight or altitude, every time.
