I've been in touch with Dynon tech support and we have not yet been able to nail down the cause or solution to what is going on. Here's the issue.
When first installed back in 2003 the D10 was in agreement with the Van's ASI to within 2 or 3 knots. Sometime recently, the spread has gone to about 6 knots on take off and on final, and up to 12 knots at cruise speed. It is indicating slower than the Vans unit and has been confirmed by working a know TAS derived from GPS runs back to calibrated speed.
The still air calibration procedure has been worked twice with no change in the error. The discrepancy has been apparent since installing version 5 but may have been there with previous version 4 software. Yesterday version 5.1.1 was installed with no change.
Has anyone had this problem and if so, how was it resolved?
