Ok - thanks- I understand that there is no hangar calibration needed, but when I look in the AOA setup- I usually see a speed indication of around 12kts - even inside sealed hangar ?
I am using the Ray-Allen Flaps position indicator - and it works fine, but I can't seem to get the donut to turn on and off. The "Use flaps position" is set to yes.
The AOA is also crossed with red - see photo.
