    AOA calibration

    I’ve never been able to get my aoa calibrated to where it is close to being accurate or trusted. Not sure if the button press during calibration is super critical or if the timing of the flying maneuver is to blame. I have the dynon heated pitot/aoa, 5600t, dual adahrs, and the tubing is hooked up correctly. Is there a way to manipulate the aoa page settings after the flying portion of calibration to ‘tweak’ the numbers to achieve accurate interpretations and display on aoa screen? I have also copied numbers from another rv10 flying accurately aoa to no avail in troubleshooting.

    You can also take a picture of the setting and we can diagnose what's going on from there.

    Interesting, it looks like you only have half calibrated or just haven't calibrated cruse configuration?

    Is your AOA donut (green circle) changing with flaps position and appearing only in landing configuration?

    The donut comes on with full flaps only, not sure how it would be half calibrated but I’ll try it again and report back with changes, but after this Michigan winter weather settles down.

    Interesting, the flap angle sensor should trigger the donut from 1/3 down to full flaps. Is your flap position from Internal EMS, SV-EMS or ACM?

    My flap angle sensor is tied to vpx, 5600.
