[RESOLVED]Artificial horizon freeze

[LeCuvier]

The other thread is already closed but with only the turn indicator problem REPORTED.

I was trying something else today and suddenly noticed that the artificial horizon indicated substantial bank although I was not banking at all.

 

I tried several times and always managed to freeze the Artificial Horizon. As long as I only turn gently the horizon works fine. But when I maneuver heavily with high banking angles, the horizon evebntually freezes and does not recover. Doing some rolls gets you there very quickly. I attach a screenshot where you see the real horizon horizontal, and the artificial one shows me banking sharply right.

Edit: this is in OB.

Edit: Did a repair and tried again. Same problem. And it also happens if I do a steep climb. See new attachment. Just see that there seems to be a new update. That might change the picture.

Edit: In the stable release I see only the turn indicator problem. The artificial horizon seems fine.

Edit: after today's OB update I re-tried and was about to shout "Hurrah the problem is gone" but then the artificial horizon froze again. And I could reproduce it again and again, but it takes far more messing around. So anybody who wants to reproduce the freeze should go through a series of sharp banks and rolls etc., and you should see the artifial horizon freeze.

At first I thought this might just be op toppling the gyro but it is not the case, the artificial horizon and the turn indicator appears to have somehow gotten connected with the elevator trim. A moderate level turn can cause the artificial horizon to freeze in place, then using the trimmer switch unfreezes it.

Yup

 

It's like I was originally reporting, there is defo something wrong here with the horizon and mine is not fixed (well not the last time I checked)

 

The difficulty is that with only some seeing this problem it makes it hard for ED to check it out

 

It's annoying as I can no longer fly the Dora IFR

 

My only hope is more do like you and anybody with it reports it

 

I'm not holding my breath for a fix

Yeah, the Horizon indicator freezes. It can be unfrozen for a moment by caging und uncaging it while trimming the elevator.

Hi

 

Yes it is reported, but I can not give you a estimate currently on a fix.

 

thanks

thanks

So the issue has been recognized. That's good news, even if a fix is not imminent. We have learned to be patient.

[wju]

seems to be fixed :-)

Confirm. the Artificial Horizon and the Turn Indicator are working. Thanks ED!
