I made an upgrade from EFIS D10 to D10A and reinstalled the unit. The instrument behaves a little odd since then. The first thing is: Every now and then at runup the horizon tumbles anround, the heading is off by 100+ degrees and the turn rate indicator shows full left deflection. After 5 seconds it recovers, but the turn rate stays at full left. At next or third boot it comes up fine.
The second bugs is this: I calibrated the EFIS to my steamgauge with the MORE MORE SETUP MORE MORE MORE ALTADJ procedure (I had to set-220), say at 30 inch HG both units show 250 feet. The next day, with the same QNH it shows 310 feet. Of course, it should show 250. (I know about the autocorrection function, but if I set the QNH to the QNH of the steamgauge it should show the same altitude the gauge shows.)It is off every day. Sometimes I go flying, airport altitude 250 ft, EFIS 250 ft, short hop, and after touchdown it shows something 50 to 150 ft off. Even without flying and powering up and down at the hangar it is not corresponding with my steamgauge (and that one is fine, I rechecked it with several other aircraft in my hangar.Every time I start the EFIS, the altitude comes up with say 300 ft and slooowly creeps down to 250ft over a period of 2 minutes, Static line seems to be OK, no water, no leaks. Any ideas? I think the first bug is software-related, my Version is 5.0.0 and the EFIS is connected to a EMS D10 via DSAB, it has an internal backup battery and is wired to a Becker Mode-S Transponder.
I hope that I don’t have to send it in for service, I’m located in Germany and the goaround time has been 8 weeks this winter.
