Hello everyone. I have searched for this question but couldn't find it here, if it has been asked before, please direct me to the thread and don't be offended.

 

I've been flying the PMDG 747 for some time, doing auto take off and full auto land without problem. Lately the aircraft is behaving strangely and I have no idea what is wrong because I'm sure I'm doing everything the same way I have been doing it since.

 

When I plan a flight or load a saved flight plan including default plans, using the FMC step feature to go through the legs, it is obvious in the navigation display that the flight path during final approach does not align with the runway heading.

 

In the attached picture below, I was going to NZAA runway 05R. I've tried at several different airports with the same exact result, you can see that the legs (stars) (LENGU, C105R, F105R, 05R, EMRAG) which is supposed to be on the line leading to the runway, are not the line, instead to the left side. Plane will capture LOC and GS and will descend normally following correct glide slop, but you can see visually and on the display that it's not heading straight and unless I deactivate autopilot at GITUK to correct and land manually, it'll go ahead following the magenta line thereby landing the plane diagonally to the runway or on the grass.

 

 

 

 This never happened before and other aircrafts like 737ngx, CS 757 & 767 still don't have this issue, so I'm sure it's to do with PNDG 747.

 

Also during cruise with no wind, the plane's nose will be pointing straight ahead while keeping the route leading to next leg which will be pointing to my 1 or 2 O'clock.

 

IRS is well aligned before flight and initial reference set in FMC.

 

Any ideas please?

I think it is a registry error. The flight one registry repair tool should fix this problem. You can get it from their site, it is free just download it and run it.

Thank you very much for the quick reply. I did that using the registry fix tool I got from FTX Support page but it didn't change a thing. I'll try and see if the one from Flight one will be different and report back.

Wow! It did it, thanks a lot. Someone had suggested this and I kept doing it that of FTX, didn't realise it's different from flight one's.
