DP Davies in 'Handling the big Jets' (essential reading for Cathay entrants many years ago') said 'The Captain of a 747 should know his aircraft's weight to the nearest 10 tons!'
Aircraft performance is pretty 'on side' with all the assumptions we make - that's why the 737 subject aircraft and crew survived. Gross error checks are one thing but we can't go down the cabin and weigh everyone as their final abuse before getting airborne - can we?
