Can someone help me figure out what happened?

[Eagle7907]

So I'm all pleased as punch about the AMRAAM upgrade, so I take a wingman and go out an shoot some bandits up. After the second flight being splashed I decide to get a bit higher in altitude (30k) to get a bit more reach for the Mig29 flight.

 

 

While climbing I accidentally nudged my trim hat and the FLCS started doing weird stuff. The jet started to oscillate in pitch. I nose over and almost red-out, regain control. Hmmm, thats odd. M.85@28k a stall? No way.

 

 

So I climbed up again, same thing happened. But this time I let it oscillate and it got worse. This time it completely departed. What?

 

 

So I regained control, well sort of. I was able to stop the rolling, but it got into a deep stall. I attemted to use the MPO, but that did nothing. it got so deep, at max thrust, watching from outside the jet looked like a heli on fire.

Any chance you had the refuelling port open? Not at my computer to watch the track.

 

I've seen some instabilities when the refuelling door open in previous versions.

I don't think so. I did a runway start and didn't do any refueling. Only thing I altered from after takeoff from that area of the cockpit was the external lights panel. I understand what you're thinking though.

 

 

I did nudge the trim hat before this sleigh ride started, but I find it hard to believe that would change the FLCS into any change in logic with the gear up?

I’ve seen this behavior several times lately but I’ve attributed it to a mission my wing is flying. At altitudes of around 30K when descending the CAS indicator in the HUD will go to 0 and the jet will start wilding oscillating in pitch to the point of blacking out. I have to hit my brakes to stop it.

Has this been reported? That’s pretty crazy. I was in a climb when it happened. Also it was cold but standard pressure.

Probe heat?

Oh snap. That might be it. I check it on for ramp start when taking the runway. Not sure if it was on this time since I was already on the runway. I’ll have to watch the track to see if it was.

 

Addendum: It was on, switch leaning towards the cockpit sidewall.
