D100 issues with airspeed

[carlmeek]

I have a few issues with airspeed read-outs on the D100 and wonder whether anyone can point me in the right direction to diagnose the problem.

Its with a Remos GX, and apparently these issues are suffered by other aircraft too, perhaps all of them.

1. The airspeed reads 20kts whilst stationary on the ground.
2. Winds aloft are total nonsense. Seems to be a perpetual 40kt wind.

Thanks,
-Carl.

There's a zero airspeed calibration function under SETUP > SPDCAL which will fix the first. Make sure to use the EFIS-D100 installation manual from htpp://docs.dynonavionics.com for guidance on how to use it properly.

Correct winds aloft highly depend on magnetic heading being correct. The first thing you can do is to re-do the magnetic heading calibration procedure to try to see if that helps.
