Tres - there are a lot of things I can't see in your video, especially the MFD instrument display, so I can't tell if you're making throttle changes/settings at the proper time. Also, what are you using for a throttle system - do you have a hardware throttle or throttle quadrant of any kind or are you attempting to run your throttle with keyboard and/or voice commands? If so, it will be quite difficult to control the aircraft, as the TBM doesn't take kindly to a non-peripheral environment.

I can tell you I flew the FS2020 version of the TBM several times a few days ago and have experienced no difficulties or changes in aircraft operations. You also stated that you made many flights with the system you were using in your video and that you had no issues until recently. Since I have seen no changes or problems, there is either a conflict with your setup OR the control settings may need to be verified for your throttle. MSFS has a history of inadvertently changing control settings with no warning so I would certainly check that your settings are still in place.

Finally - be careful of your procedures - monitor the MFD instruments closely:

• Set LO-idle AFTER having obtained 13 % of Ng. I reach for the throttle as Ng is passing 12% so I don't engage that position too early. You appeared to move to that position early and that can cause damage. From the manual: When throttle is positioned on LO / IDLE before having obtained 13 % of Ng, there is a risk of overtemperature further to an excessive accumulation of fuel inside the combustion chamber before ignition.

• I recommend moving the throttle to FLIGHT-idle when Ng is at 52% and run everything from that position (including taxi) until you begin the shut-down sequence. I reach for the throttle for this as soon as it passes 50% and then initiate the move around 52%. You left the throttle in LO-idle for quite a while - I don't recommend this

• Check your throttle Reverse Axis assignment. It appeared that reverse prop initiated at one point when you were taxiing. If this stayed in reverse, you would no longer have been able to move forward.

That's all I can think of for now.

Very difficult to see what's going on here I'm afraid.
For example, when you command Idle at the end of the runway did the throttle actually come back? Can't see in the video.
One thing I do remember was when in the scrub, it was challenging to get any motion. I know you said you thought you were at full throttle but on the video it doesn't look to be. But probably a minor point once the TBM hasn't responded to the command to idle.
I also remember that TBM throttle being a bit twitchy - e.g. going to reverse a bit to easily.
Final point and without critiscm - have you checked full startup procedures? I found anomolies if I didn't startup correctly - autotrim on, auto fule pumps for example. Clutching at straws here.
Same at any other airport?
I'm sorry I can't shed further light, but if I had to guess I'd say issues between voice commands and what the TBM is actually doing. Without seeing both perspectives it's difficult though.

Guys thank you very much for your responses.

Randall I am focusing on the reverse axis issue. I had a look at the keyboard bindings and the mouse bindings Only to discover that there are no inputs called for; everything is blank. At first I thought that was fine but now I am really focusing on the aircraft's behavior and how it does this going into reverse thing. Can you give me any guidance as to what the correct keyboard bindings should be? I use classically the old FSX keyboard actions of; first hit flight idle, F1, and then holding down the F2 key. I'm not sure how to express that or whether I should use propeller or throttle management, or both. Those inputs must have been there, but right now there is nothing.

I should point out I do a joystick as such; my right arm doesn't work properly and I can't lift it up to operate one so I use Vjoy and virtual controller in conjunction with the mouse. You may remember I was telling it “secondary click” to throttle over to the left side. It isn't elegant but typically it does work.

Again, thanks very much for your responses fellas.

Tres

Well, i'm a little embarrassed that I even had to ask in that Last Post; it was pretty obvious all one needed to do was hold down the F2 key.

So I did that and now she's behaving like a Princess. All I've done so far is taxi around but it just has a different feel. Once again thanks very much you guys for your help.

If you still have any issues regarding Reverse Thrust, here's some info on the default and some of my assigns:

Command - Toggle Reverse Thrust:

• Keyboard Default: Unassigned!

• On my throttle: Assigned to a button. One press toggles to reverse. Even though I now move my throttle forward, the prop gives me reverse thrust for braking. Another press of that button toggles back to regular on the prop.

I did program an alternate into my own keyboard profile in case I ever lost it on the throttle: Ctrl+R
