Just would like to know if anyone uses this program with the NGX?If so, how is it used? Do you load the plane in both the program and the CDU??

Just buy the aircraft, start a flight, then in the options disable modifications to the aircraft cfg. Essentially you want to disable FSPax weight/cargo/cog loading so that PMDG decides what the ZFW/CoG/Fuel load of the aircraft is, not FSPassengers. Once you do that, load the aircraft in the FSPax menu to the same specs as in your FMC and you're good to go. Everything will work seamlessly because FSPax won't be modifying the aircraft cfg.

Cool no worries? Where do I turn this off? I've brought the plane, have started the flight, where in the options to do I tell it to not alter the ac cfg file ?Is it in the flight & aircraft setting?Then is it disable payload and fuel up date?

IN NGX FMC: Set desired fuel, set payload to empty. Start FSPax: do NOT modify fuel, set pax and cargo as required. Works like a charm.

Is there a way you can get the manifest and pax numbers, load the flight as per normal then manually input all the weight data??There was a option in the settings to disable the Pay load and fuel update? If I do this would I be able to do this?
