Well, I love to do some transatlantic flights. But, those flights are very longs, so, with 99 % of my flights I use the time acceleration.

BUT, with the 767 captain AND with the 757, I can't use that feature cecause, as soon as i start the acceleration, the aircraft beguns to climb and decent more harder at each times like a rollercoaster.

It don't happen with the 727 or with any others aircrafts (even if I have a Low FPS) Somebody know why ?

Also, in the next service patch, it is possible to fix that problem ?
