Ok thats good to know - how about stalls - how does it react?
YAsim models some simple stalls. You definitely know when you've stalled. True life stall behavior is very difficult to model because it can be so different from aircraft to aircraft. There seems to be a small issue in YAsim with some strange behavior when your aoa goes a little past negative. I was looking at that last night and today, but quickly got in over my head. Hopefully Andy can figure this out without too much additional work. When you fly in the normal regimes you should almost never run into this problem.
For whatever it's worth, some people like to hop into a sim and evaluate the flight dynamics model by taking it to the extreme edges of the flight regime before looking at anything else. If it feels right, the sim is great, if not the sim stinks. In this case, who here has stalled a Citation Jet? Who would know exactly how it reacts or doesn't react? How easy is it to recover in real life? If I told you it stalled exactly right would you be able to prove me wrong? If you told me it didn't stall right, could I prove you wrong?
I'm not a full scale pilot, but I have flown a variety of R/C aircraft. They all have wildly different stall characteristics.
So who knows... I think the YAsim Citation has a plausible stall but I have no way to say if it's anything close to realistic or not.
