A question about the flight model
-
Recently I started Flying Bms again. I never tried to test the flight model on extend. Last flight I was fooling around and managed to make an outside loop…is this for real? My pilot was on the edge of red out the aircraft on the top reached 70 knots and almost went on a flat spin but I managed to dive and go on my flight, without the outcome I would expect really… Is this a fault in the flight model, is this for real or something we just have to accept and keep enjoying the best sim today?

It is for real.

Perhaps review the Flight Model developer notes:

the FM is good enough to recreate this?
I never experienced such behaviour that it is not do what i want. only in Stall -

I have seen this is a special config they do at Edwards …shouldn’t be possible under normal circumstances because the FLCS will stop it.
To recreate that the fuel needs to be balanced out in a way that puts the CG close to the aft limits. This apparently prevents the horizontal stabs getting the authority to keep the aircraft in control.

@repvez - yes, I should think that the BMS model could reproduce this, but the key here is that this is an asymmetric stores load out, so the jet is unbalanced to begin with. So…good hunting if you should put this configuration into a TE and check it out!
Personally, I think this sort of thing is one of the more fun things to do with BMS - virtual Flight Test.
