It did happen to me several times now since one week...Here's the typical scenario :I log in SB on IVAO, everything is allright, i load a FP with FSNav, and after a certain time flying, the engines RPM goes at max with airspeed indicating ZERO. The auto pilot seems to be completely messed up and the plane is out of control.What i do in this case is switch the autopilot off, and manually take control back of the plane, but i still have to wait random time till i can read airspeed again.this bug is totally random.When i fly offline i have no prob at all.I'm using SB, HostSB.dll, and fly on IVAO with FS2004.Strange thing is that this bug appeared when i did install a new plane but i don't know if its related or not. Everything has been working properly for weeks until this happens for the first time.Any clue ?

Pitot heat perhaps? ;-)Regards,
