Hey FolksFor sometime I've been trying to coax a contrail out of myPosky 757's. I downloaded fresh effects and air files fromPosky n' Avsim but to no avail.Meanwhile all my other aircraft just spew away.If anyone might have any idea, I would be very greatful indeed.Thanx.

HelloI was using the POSKY 757 last night,and the contrails were showing.Make sure you fly at say fl34 and try Northen latitudes.(keep it cool)cheers Andy
