With throttles at idle I have found that a certain aircraft (Concorde) when low on fuel (say 20 percent) after a flight slowly edges forward. I assume this is caused by a combination of the thrust of the engines against the weight of the aircraft which with a low amount of fuel is less (hope I explained that bit right). Is there either a way of increasing the effectiveness of the PARKING brakes or something else that might work around this problem.I can confirm that it is not the calibration of the throttle I have tried it out both with and without joystick enabled.Andrew BrownACPChttp://www.gordiusfs.pwp.blueyonder.co.uk/

Hi,There is a known problem with the friction coefficient of FS that was fixed in a modified file that ships with FS, and I think it is possibly available here at AVSIM.Which Concorde are you reffering to BTW? If you have the Concorde SSTSIM, this was corrected in the update.Note that if you fly the Project Tupolev Tu154B2 you will need to restore the original file as it was specifically designed with the default coefficients in place (they frankly have some dam* good programmers over there - they truely know what they are doing).If you don't have that, check it out! :) http://www.protu-154.com/Best regards,Vulacn.
