(Apologies if this appears twice, but the first post seemed to disappear.)Was going through the 'standard procedures' tutorial for the 747 and kept crashing.Whenever I did pushback I was rolled back and turned, and the call for parking brakes would come. Parking brakes on but I was still rolling back. Parking brake on with engines on or off and was still rolling back. Foot brakes didn't stop it. Just rolled slowly back until I hit a building and crashed.Tried a search here at Avsim for the problem, but couldn't find anything.Anyone know what the problem is?Something I missed in startup?Any ideas?

I'll ask Vangelis to take a look at this... Did you try pressing Shift-P (the default command for pushback) or pressing the pushback gauge button again? Those are both supposed to reset it.

Same prob a few days ago. Flew KLAX-KDEN, but did not save the flight nor close down FS; instead loaded RC plan KDEN-KORD. I went thru the prestart, pushback and start checklist (FDC and RC). When I set brakes, a/c continued moving backwards- reset the pushback gauge at least twice, pressed "Y" for slew, had to close the program and start again.louross.

Pressing Shift P stops the plane, but unless you do that it continues to rollback.
