First of all not sure if this is the right place to be posting this!

 

Does anyone here use PFPX, Topcat and 737 ngx? What My problem is the ZFW is different to the one in the 737 800 WL single class FMC - PFPX ZFW 42991

737 ZFW 41400

 

I have configured those two plans together by only using adults set to 79kg!

Do you use TOPCAT to load the aircraft? Please don't.
