What do you mean "calibrated" for AS and OAT?The airspeed is calibrated, as is altitude, oat. I havent performed a magnetic calibration since initial install.
Winds being off = almost always come from an angle from Left side of aircraft , mostly cross head wind , even when I know the wind may be from the Right( eg if Im laying off drift). Any other thought would be welcome. It would be good to have a function that gives a credible reading! The only other thing I can do is repeat magnetic calibration, even though my headings and tracks seem to be ok.
