Hi Lib and welcome to the forum.

I don't fly the Lear much but to answer your question, yes it could be icing although I wouldn;t expect it to have an effect on the glass instruments in that panel.

All sorts of icing effects are modelled in FS2002, but they only turn up under the right weather conditions.

If you've been flying with real weather, I'd suggest trying a test flight without it and see if you encounter the same problem. You shouldn't get any icing with the default settings.

If it still occurs, can you confirm that you're using the default aircraft and panel, and if not, which ones you are using?

I've done hours and hours of experiments with fde/autopilot characteristics (editing the air and cfg files)and the thing you MUST remember is that the MS autopilot is far from perfect. At best it is a massive compromise between the various factors that have been built into the fde modelling - and unlike a real simulator costing millions of $$$$, MS have had to do the best they can with a relatively simple model that people can afford to buy and install on their PC.

Example - It is well known that MS have NOT created a fully working turboprop autopilot. They were unable to create one that has autothrottle incorporated - check it out for yourself on the Caravan, Kingair and Dash 8.

Without blowing my own trumpet too much I still think the best one I've come across is  my own one in my updated fde for my Dash 8 (many months ago) that took me hours to do. That works to something like 95%+ capability but I still found that after extensive testing I had problems with speed control during turbulence (but not bad in still air at all speeds).

In testing I found that when modifying certain parameters I got some strange effects. For example, in descending turns to the left, the aircraft would dramatically begin to lose height while the turn was in progress - even to the point of crashing emabarrassingly if turning at low level on final approach. But it didn't happen in right hand turns!

I won't bore you with ay more stuff -  I don't fly the default aircraft hardly at all so I don't know much about the Lear. As the Mooney fde is cobblers I would not be surprised if the Lear one is also. It certainly sounds as though you have been experiencing similar problems to the ones I found when I was playing around.
