Hi all I installed the pmdg sound update for the 747 , now my lnav and ap do not work correctly in the 747 or 747fCan I reinstall the 747 and updates and then sound or do I have to start from scratch with the 737. I really do not want to go back, can i just install the boxed product and then then the 747f and then soundOR;is there some other reason lnav would stop working after the sound installPeter

Peter,The sound update has absolutely nothing at all to do with the AP - it is wav files and a sound.cfg, nothing else.What specifically is the AP doing?

>Peter,>>The sound update has absolutely nothing at all to do with the>AP - it is wav files and a sound.cfg, nothing else.>>What specifically is the AP doing?Thanks for the replyThe AP will engaage.LNAV will not engage, If you click the lnav button it will not engage.I have irs set to immediate and the fms is fully programmed.This is happening on both the 747 and 747fAs a note I think that this was all good before the sound update but perhpas im wrong.I have been using the pmdg 747 product for a long time., Ive never seen this before.. Thoughts? By the way the lnav shows up on the pilots in the display in front of the pilot ( in white) but will not engage.Peter

Peter,Any chance you could email me the flight files for this situation? Just get it all set up right to the point where you'd engage LNAV and then save the relevant files and email em to me - [email protected]'s instructions on saving the flight:http://ops.precisionmanuals.com/wiki/PMDG_...to_someone_else
