I am flying 1.1.12 now using EFM and it's working fine. I believe that it's built with the EFM in mind.

Yeah, good point and that thought crossed my mind as did some others, though, I can't remember if I thought about it before or after the crash. It happened very fast and, to be honest, I was caught by this fairly flat-footed. Here's what I have thought about after the fact: Should have pulled power immediately (common sense). Would the airplane have continued to upside down if I'd have done that? I might have been able to roll out of it with aileron and turned the autopilot back on. (Though, it begs the question, what next? How do you land a TBM on autopilot with a broken trim system? ILS, zero flaps to keep the nose up, and land at the lowest speed possible using a bit of power to slow descent before touchdown? At best, a controlled crash.) I should have done a replay and looked at the state of the trims and other things before it happened. (e.g. it's a kind of flight recorder.) I could have also recorded the playback. Why would an airplane be built to commit suicide and kill its passengers? This is the opposite of what airplane manufacturers do. If it was the trim system, why couldn't I override the dive with control input? A trim system is only so strong. A TBM is not a Cessna but I did have to demonstrate that I could override the trim system in Cessnas when I got my PPL. I even had to do it on the day of my exam. It takes some strength but it can be done. From that perspective, it seems just as likely...perhaps more likely...that the elevator control wire snapped. There was nothing I could see in the log which said what had failed. Was the fact that I had to click the VS button twice in any way related to what happened? Very unlikely that it was an icing thing. I was on top of that on decent through clouds, no precip, and the weather was warm when I got low. It wasn't a weight and balance thing since the airplane flew fine on autopilot. A WB problem would have been just as bad under autopilot.

I have. Not a peep so far. I'm seriously hoping there's something...another option other than crashing. Gregg

Ok. No, there was no 'drop in' this time though I have seen from light 'drop in's from time to time but I did check the maintenance. The departure was very ordinary and I hand flew it up to about 10,000 without a problem. No turbulence either. So, the only solution is to let it crash??

Well, the obvious question is...what do you do? I mean, you don't see airplanes flying out of the sky so there must be something...?

I did check maintenance before the flight and it was clean. The flight was only an hour long. Lord, a trim failure in flight can do that?? I pulled my yoke to the stops and got almost nothing. I'd have thought you could manually override even if it was difficult. EDIT: Also, wouldn't it have said something about a trim failure in the log?

I've done about 100 flights in the TBM. This was my second on 1.1.12. I was on a short, relaxing morning flight on VATSIM, from KCLT, coming in for the ILS into KSAV, on dogleg to final. Was just getting ready to put down the first notch of flaps, power was about 30 Torque, 190 KIAS. All seemed pretty normal. I'd set 2000 ft in the Alt window and VSed down about 1300 fpm. When I looked up it had flown through 2000 and was down at 1600. I disconnected the autopilot and, at that point, the airplane immediately nosed hard over. I pulled back on my yoke all the way and it only slightly helped. It dove straight into the ground and crashed. I've never, ever had this happen in X-Plane before. Any thoughts as to why this would happen? Logs attached. EDIT: I'm using X-Plane 11.41. Gregg Log-crash.txt TBM900_Log-crash.txt log_200405_125833_KCLT.csv

Beautiful pics. I definitely like the reflections on the G1000 screens (though you may want to tone it down to a matte finish) and the attention to detail on the electrical system. I'm hoping there's similar depth in the other systems. Do you plan to have an option to save state between sessions? (Switch positions, maintenance, etc.) Gregg

Ah. I was flying on VATSIM at the time anyway. I had Traffic Global set to 0 but I'll uninstall it before my next VATSIM flight. Have to say, I reloaded teh flight and started over...and it ws gorgeous, beautiful flight. Did a practice approach to a missed and came back around and landed. Flying this thing on VATSIM is a lot of fun!

How are your other planes (and are any of them single engine turboprops?) Just to be sure, have you checked your yoke calibration? Once you get to altitude and level out, does it fly straight hands-free? When you're climbing out and it's trying to turn left, what's your trim at that moment? The trim in the sim should be sufficient to counter the forces of torque and prop wash. Gregg

One thought occurred to me. When the generator tripped on me, I was in moderate to heavy turbulence at the time, in climbout. Just in case that could have had anything to do with it. I mean, I can imagine that the instantaneous measurement of some value during that time might have been low or high, though, the gauges looked okay from what I could see. I have noticed that sometimes when I've gotten a hot start, the engine caught fire while ITT was still in the green, increasing quickly. Perhaps that gauge lags behind the actual ITT? Or maybe I was just missing something in all the bouncing around.

It's when you bring up the Change Flight dialog (the little airplane in the upper right corner) and there's a button in the upper right corner of that dialog that says "AI Traffic" or something like that. I'd remove all aircraft from that.

I've wondered about that too but try cutting power 1-2 seconds prior to your flair. Lots of RW pilots on youtube use that technique.

Well, I'd deleted the 'state' directory so I don't know if it was set or not. Maybe it was, though, that would have been by accident. *Sigh*

Don't think so...at least not intentionally. I'll check.

So, this is about my third flight in this airframe and I got this: Then the engine shut down. Attempting to restart resulted in an engine fire in flight. What would have caused it to wear out so quickly? Does a generator malfunction cause engine shutdown? There were no other notifications in the log. EDIT: I'm an idiot. I see that the gen tripped and then it was the engine that failed. Still, I didn't run it over 101% and that would have been only a couple of seconds. About 2 hours on the engine. Gregg

Yeah, I'm not sure if it's related to those two missing ortho tiles or not. There are a number of folks having issues...not just with the TBM. I'm trying to track it down. Seems to be related to OpenGL on the Nvidea drivrs. Tried several drivers. It's all guesswork but the common theme I've been thinking about is FXAA. Not sure...and you really can never be sure.

I´m not sure Traffic Global works if you enable it as AI traffic (meaning put their AI airplanes in the AI traffic window). I had some in there and got a crash which *may* have been related to that so I took them out for the time being...just in case. In truth, with the TBM it didn't matter if they were in there or not because they didn't seem to show up on the MFD anyway. But at least I can see Traffic Global planes out the window so that part works great!

I tried it and it seemed to work pretty well, apart from the nose of the airplane bobbing up and down gently in flight and on the ramp. But the same thing happens with my other planes so it´s not a TBM problem.

I wanted to add, I think this is happening to A LOT of the planes when using expermental mode. Not just the TBM.

I'm not sure that there is anything that can be done about it or if it's the desired effect or if it's, possibly, even only my sim. The airplane bobs up and down both on final and on the ramp. In a five knot wind on the ramp sitting still, it bobs like the wind is much, much stronger. On final, coming down at about 90 knots, autopilot on (the wind about 10 knots or so off the right front) the nose kept moving up and down as well. Maybe that's intentional to fake vertical air movement. To me, to fake vertical air movement, the entire airplane would move up and down...not just the nose. Curious what others think about this. Gregg

I'll try. I've had that for a while, though. I just updated both the TBM to 1.1.11 and then X-Plane to 11.41. I never got a CTD with 11.30 with 1.1.9.
