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.
