Question about payload assumptions

Firstly Robert and Crew.... I am stunned. The plane is absolutely fantastic. You have helped me re-discover my past love of flightsim. Im having some CTD's when switching planes and loading flights, but will try and figure out if that is me doing soething wrong. Beyond that, it is flawless! Well done! Question:What are the payload/loading assumptions used in the CDU based loader? I ask as I would like to draw up some loadsheets out of Topcat to help with flight planning and would like to mimic the assumptions built in to the PMDG NGX. Specifically:- what is the weight of 1 passenger? (does this vary between single/dual class?)- any child/infant assumptions built in?- what is the modelled ZFW? (does this vary between single/dual class?)- does the passenger weight include baggage? (and again does this vary between single/dual class?) I did try working it out, but it is hard with only 1 decimal place in the CDU! Appreciate your answers should you find any time. Again - brilliant job guys. Its a pleasure being your customer!
