Hello, I have the following setup in my Europa monowheel:
- D10A EFIS
- D10A HSI (DSAB master)
- AP74
- HS34 connected to GNS480 and AVMAP IV
- SV32 pitch
- SV32 roll
All running v5.6
Very good setup. Pretty happy. I have the following autopilot parameters that allow to maintain +-50ft altitude in all conditions.
I am facing one strange issue: from time to time (happens every 10-20 flight hours), it seems that the the pitch servo is not commanding (even if it is announced as commanding) the plane that loose altitude. When that happens, I disconnect and reconnect and everything is back OK.
That started to happen when I modified the pitch parameters. In the beginning, I had huge oscillations with the smallest turbulence. Pitch was really not stable. Then, I really spent time to find an optimal set of parameters. But now I get this issue of pitch servo not controlling the aircraft from time to time. If I remember correctly, that started to happen when I modified the pitch and alt gain parameters. But that could be a coincidence.
What could that be?
