It might be a problem just related to that or other binding. Do you remember V ref, flap setting, OAT, lndg wt, airport elevation? All these are a factor. Something to remember, on previous versions (P3D) was an issue. I can duplicate your flight, I have some time available for the next 5 - 6 hours. This most recent example was PAJN to PASI. I landed with flaps 30, normal braking (no autobrake) and reversers. Once the plane comes to a stop, I can only get it to inch along, even at takeoff power. Btw, I also checked to make sure the chocks weren't set. https://www.mediafire.com/view/dz3buh31pti9cej/BoeingDriverSignature.jpg/file

May 27, 20224 yr Author I would also add as a general rule, that excessive braking (say in a very hot environment) wouldn't have this effect on the aircraft. Indeed, it would reduce the braking effectiveness until the brakes had cooled or been repaired. https://www.mediafire.com/view/dz3buh31pti9cej/BoeingDriverSignature.jpg/file
May 27, 20224 yr I have experienced the same thing as no tire blew out or anything issue, the plan cannot move with moderate thrust, you have to apply the maxim thrust to push it forward. it is such an embarrassment.
May 27, 20224 yr Author Just tried a couple experiments. One landing with no reversers, just toe brakes. The problem did not reoccur. Next flight was with reversers and no brakes, and the problem reasserted itself. So it may be something going on with the application of reversers. I checked for double mapping but will look again. https://www.mediafire.com/view/dz3buh31pti9cej/BoeingDriverSignature.jpg/file
May 27, 20224 yr What it shows on brake temps when this is going on? 747 Captain for the last 39 years, and still learning.

If you use the reversers as a button to reduce thrust, the PMDG doesn't cut back to idle when you push the throttle back forward. I've gotten in the habit of pushing F1 to set the throttles back to fwd idle when I'm at about 80 knots, then It should be fine. my first PMDG flight ended how you describe, til I realized that.

That sounds plausible. I'll check that out (I was using F2 to engage reversers). https://www.mediafire.com/view/dz3buh31pti9cej/BoeingDriverSignature.jpg/file

May 27, 20224 yr I have had the same thing happen after landing and have come to a stop, I just tap the toe brakes and the brakes release and continue taxiing as normal.

Very intriguing, on my PC if I use F2 to get reversers and just push fwd throttles they come out of reverse without pushing F1. 747 Captain for the last 39 years, and still learning.
