I have a MX1 and ASV1 that both read 150 feet below field elevation with the current barometric pressure set in each. I seem to be able to adjust the MX1 calibration factor to get the correct field elevation. When I attempt the same in the ASV1, I can get the altitude to read correctly but my airspeed then indicates 65 mph...in the hangar. I'm sure I am doing something wrong. Anyone have any advice or recommendations?
