Question from ignorant small plane driver.
How is weight and balance calculated in a 744?
Assume it has a datum, just like small a/c's plus max/minimum weights of fuel allowed in each tank (I understand there are tailwing tanks).
How do you factor in pax weight/luggage/freight weight?
Assume there is a preformulated loadsheet which ground crew fill in for you and you sign off?
Is this process digitised in any way?
