Sudden Torque Drop then Rise when Climbing
-
I notice a strange bug. Sometimes the torque is bugged: it drops quickly and then goes back up, past 121%.
See here, at around 00:28

It seems to happen randomly between FL210 and FL270. -
I occasionally notice the same. My assumption:
The torque depends to speed, altitude, temperature & icing level. At the same time changes to the weather including high altitude winds in MSFS are rather abrupt, resulting in erratic torque behavior.
If this is true I guess there's not much that can be done except Asobo/Microsoft further improving the weather system.

I don't believe it's due to that. If you watch the video, you can see on the GPS that the wind does not change.
Moreover, when the wind does change, the whole aircraft moves. This is not the case here. -
Thank you very much for posting a video of this. It confirmed my long held suspicion about what causes this. If you watch the altimeter needle in the video, you can see that it becomes momentarily hung-up and then jumps ahead during the same time as the torque reduction. This is caused by a momentary hiccup in Asobo's code processing, where animation code does not execute on time for a few frames. This causes the time keeping variables in my custom engine simulation to lag behind, and cause the torque reduction. Unfortunately, there is nothing I can do about this, other than moving my code into an application outside the simulator, which is not a path in development that I'm willing to take, since it multiplies complexity, and precludes the products from being deployed on XBOX. All I can say right now is that none of my other turboprops should suffer from this problem, just the TBM, because of its torque limiting logic. Thank you for sharing the video!

I noticed this in other aircraft too (Altimeter momentarily freezing) I believe I noticed it in the A2A Comanche too, but it doesn't affect the engine/torque like in the TBM. Glad I'm not the only one that noticed this. Thanks for confirming this as an Asobo bug.

@Black-Square Thank you for your reply. I suppose this overtorque is damaging the engine, I will try to keep an eye on it.
Keep up the good work, apart from this issue, the plane is excellent! -
Thank you for the kind words. If it's any comfort, I believe that issue should only ever produce an undertorque, not an overtorque.
