Airspeed Mismatch with Sport EX and calibration
Posted: Tue Sep 20, 2022 3:40 pm
Hi, I have a Horizon 10.1 and a Sport EX MFDs connected to the same pitot/static system of my aircraft. In flight at cruise speed, there is a difference of approximately 1.5 knot between the two MFDs. Is there a way to calibrate indicated airspeed?
Also, i noticed that my ground speed is always higher than my true airspeed. This is true for both EFIS. Of course, since both screen do not read same Airspeed, calculated wind differ from one MFD to the other.
Is there a way to perform a true airspeed calibration to correct the situation?
What could be the cause of an airspeed under reading? My Static Port is located in the pitot tube, from the kit plane manufacturer.
