Hello guys,

I had about 35 flights with the MD-82 so far. 

However, on the flight yesterday from LEMG all was well from until climb (Leonardo MD-80 addon for P3D). About 6000 feet I turned to the left following the SID and the plane slowly started to lose it climbing ability, eventually making me having to pull back on the yoke to recover until the plane eventually entered a dive, oversped, and crashed into the ocean. Unfortunately, due to my surprise I did not have time to document the situation.

I then went into the load manager, and did the weekly check to make sure the aircraft is ready to go again.

Tonight I flew out of LOWW, climbing through FL150 and turning slightly to the left on the OSPE3D SID, and the same thing happened again. The aircraft was in a clean configuration and speed was near 270 knots, RAT -2, no visible moisture, so engine and airfoil anti-ice were turned off shortly before. The plane slowly started to loose its ability to climb while handflying and yet again slowly started to dive (MCAS style), and turning the autopilot ON caused the dive to turn violent. Pulling up on the yoke did not work so I pulled it down, and then up again and finally managed to exit the dive, and continued to climb turning on AP shortly after. No issues after that.

Now before I rule out a possible fault with my joystick, is there any scenario or situation that can cause the elevator to jam, as I only seem to get out of the dive with force? It has happened on a previous flight out of LOWW as well a few days ago. I did not have this issue on my first 30 flights or so. 

Would certainly be interesting if I am seeing similar issues to what caused Alaska Airlines Flight 261 crash... 

I originally posted this in the Maddox X forums, but received no response. So I thought its best to give it a shot to post in the general forum in case the real MD-80s series or DC-9 had any of these issues. 

Thanks

Well if you can see the elevators move on the external view, they work. (I suppose you looked for failures?)
Sounds rather like a thrust issue (had that a couple of times with the CRJ, howevery I was using anti-ice), you should easily see the climb rate go down rapidly before that happens. As for why this is happening you need to monitor thrust values and the throttle position, gross weight and anti-ice (though that shouldn't make the aircraft stall at FL150). Oh and icing, though I don't remember how that is modeled on the maddog.

Thank you for the tip. I will try to check it in external view next time.

Maddog has icing simulated very well, and I strongly suspect that ice is the reason considering that I gain control after a dive (RAT temperature increased due to the stress on the aircraft skin from all that speed). Anti-ice was off as according to the manuals I was not flying in icing conditions. 

I had the climb rate decrease as well before the dive, so I will fly more carefully and if it keeps happening I think that the simulated flight recorder might be able to show some data of potential mistakes.
