I have a d180 and never have been able to get the airspeed and gps speed to match. I have flown many calibration circuits and gps is always 3 to 5 kts slower. Also the wind vector arrow almost always shows more headwind than actual. For example if it is showing 10 kt headwind and I reverse course it does not show a tailwind at all. I have done the zero wind static calibrations several times and experimented with different static port locations and port sizes. Is there a way to calibrate airspeed other than the static zero? Any other ideas?
