&47 will not follow the magenta line

[engwerda 0]

After getting the 747 in FS9 working under Vista I have discovered that it will not follow the magenta line in the FMC. It works with the 767 using the same flight plan, way points and environmental variables but not the 747. It flies off to the right and stays about 5 nm away angled at 20 deg left to the magenta track. As I get closer to the DEST it becomes even further off track. I have tried HDG SEL to get back on track , which it does but when I reengage LNAV then it goes back to being off track. I know this has been raised before but I could not find it with a search of the forum. Can anyone point me back to that thread or help out?Gerry

Bless you Dan. I will try to sort this out tomorrow using those suggestions. As always thanks for the prompt help. I am sure that they are not paying you enough.Gerry

Pay??Beta testers don't get compensation, thank goodness. I'd been fired a long time ago after all the errors I make.
