1. They had loadmasters to do that;By the way, I can do a Percent of Mac weight and balance. I have handed my load out to an Air Force Load Master of a C-5 and after about thirty minutes, he approved it as is!!!
Do have any idea how many ARMY pilots are capable of doing a Percent of Mac weight and balance? Less than one percent. Army aircraft use Reference Datum Line type weight and balance which is common on small aircraft. Percent of Mac is done on LARGE aircraft.
I can also do Rhumb Line navigation. Most Army pilots have no idea what a Rhumb Line is.

2. Now they have sophisticated computers that do a much more accurate job. All the pilot has to do is consult his instruments.
