Is it me or all the a/c in X hard to stop? Even the fast movers with autobrakes dont act like the similar a/c in FS9.Is it a a/c config thing?

I haven't noticed anything different. A quick check of the a few aircraft.cfg files didn't find a difference between FS2004 and FSX settings.Many folks have been asking for years for FS to make runways 'slick' and poor braking action in certain weather conditons. I doubt MS has achieved that.

Braking seems fine to me, unless its on ice in one of the missions :)
