Rapid drift of Attitude Indicator


Machalot

Recommended Posts

On a recent multiplayer flight I observed a fast bank angle drift rate on my Attitude Indicator.  After a short cross country flight with very little maneuvering, it had drifted almost 5 deg toward a left bank indication.  It seems too fast to be realistic, but I have no data to back up this feeling.  Has anyone else seen this?

 

Track is attached.  I was able to watch it at 5x realtime and see the effect.  It is especially bad after I make the left turn inland toward the destination airport, and gets progressively worse as I descend for landing.

Yes, I have noticed that the F5 attitude indicator easily gets out of sync with the true horizon, after doing any significant banking or climb/dive maneuvers.  I flew the T38 in USAF pilot training, it did not have that problem.  So, I think it is a simulation bug that needs fixing.

I had the same issue ... And with a bigger deviation too.

It seems to be a known thing, but I don't know if it's an issue or not ...

 

But you can use the "Fast Erect" button near the artifical horizont to reset it  ... note that you'll need to use the standby attitude indicator to level and then use the fast erect button.

Interesting thing about this I found is (I dont know if it plays trick on my mind or is real), If you startup but leave radar OFF, then the ADI will drift. If you startup and switch radar to STBY and then ON after take off, ADI and horizon on radar scope will drift. But strange thing for me is it does not happen if you start up and leave radar in STBY for the duration of the flight, ADI will not drift, it will stay aligned no matter how many crazy maneuvers you do.

Yes.

I'll try that. Sounds like a collection of bugs.

I seem to recall having the standby indicator drift as well sometimes.

Has ED acknowledged it? 

Not as far as I'm aware, no.

The last message from ED was "can't replicate". If it indeed doesn't happen with radar in STBY, that could explain why @NineLine did not see it.

It may be related to the issue I reported here, example track attached in that thread
