Calculated vs real take off weights?
I was having an interesting discussion the other day, where we were talking about the assumptions made for passenger weights etc. Now, from what I understand the average male passenger weight assumed is 84kgs, with approx 3.4 kilos of hand luggage?
Obviously the aircraft weight is added to the load, then zero fuel weight added to the fuel load to give the COG & moment, plus AUW.
How close in the real world is calculated compared to actual AUW, assuming no silly mistakes, just difference between the industry standard assumed weights and the actual load on board?
