Do they just assume that (conservatively) everybody in the cabin is 100 kg for example or do they use some creative mathematics/modelling?
What if you have a whole plane full of rugby players... surely they will be much heavier than a plane full of high school children on tour?
There are established planning figures for average pax weight+carry on etc. Likely to be conservative (high-side). We need a current flights ops planner to provide a contemporary explanation.
