John... agree with you, however, my point was, if you have the basics down, you don't need all the "newfangled" automated cr@p to work this stuff out...
For example...B-727F...12 pallet positions...find out how much each one weighs and have them loaded accordingly...too heavy?...take less fuel and make a stop or leave a pallet or two behind and go N/S...
Oops, leaving a pallet or two behind makes the remainder of the load out of limits...NO PROBLEM!!!
Rework the numbers, rearrange the pallets and go on about your business...makes life hell for the handlers I know, but in the final analysis, it is "simple, really"...Yes Really...
