AOA System APPROACH AOA REFERENCE NOTE: For information on calibrating the Approach AOA, refer to the calibration instructions in Appendix C of the AOA System Installation Manual. The Approach AOA Reference (green circle) and the adjacent green bar annunciators should be calibrated to coincide with the published approach speed (if provided), or the speed upon crossing the runway threshold that is required in order to achieve calculated (or desired) aircraft landing performance. This speed is typically equal to or greater than 1.3 times the published stall speed in the landing configuration (Vso) LOW AOA WITH APPROACH AOA REFERENCE A low AOA approach is indicated by the illumination of less than four green bar annunciators and the Approach AOA Reference (green circle) annunciator.
