Hello All! got a brain teaser here! I'm running Prepar3d v 1.4 with PMDG MD-11 for FSX, no other addons are added - I used FSX2Prepar3d to install the aircraft. Everything works fine except the runway heading vs navigaion display and auto pilot are off. The aircraft dows not follow the localizer on ILS approach and seems to be selecting a different runway approach heading. I've read all there is to read on the subject available on the internet. The standard answer is to use the Flight 1 registry tool which I have in every concivable manner. I realize the aircraft uses the registry to steer its guages to the magdev.bgl file in the simulator (I have replaced this file). All I really need is to see the actual registry entries for some one who does not have this issue and is running the MD in Prepared. Since the flight 1 registry repair tool is kind of a black box I need to know what its output actually is in the registry and what excatly the MD is looking for in the registry (ie. EXE Path, SetupPath, etc.) Photos below show the MD in FS9 on the same KDFW rwy and station dec for VOR TTT at 6E. The other pic shows the MD in Prepar3d on the same rwy the ND display shows the rwy hdg offset of 5 deg (and TTT Stat. Dec at 00 - Im running windows 7 64 BIT so registry entries are in a different location. I appreciate any advice.
