As i want to make my flights more realistic with correct weight of cargo and fuel. I have a question about the fuel consumption.
Where can I find the fuel consumption on average per hour of the aircraft you want to fly with at that moment?
There are a few online planners, but these are usually not for the oldies we fly

And for example during the trip of the week it is indicated how many passengers there are, how do I adjust these in Kacars.
And wat should i take as average weight for an passenger to calculate my weight?
If there are more tips, I would like to hear them please
