Trick Question

26.9k Sunnyskies  8.4 years ago

The allowable cabin load of a C-5 is 150,000 pounds.
The C-5 has 36 slots for 463L pallets.
The maximum capacity of a 463L pallet is 10,000 pounds.
An empty 463L pallet weighs 290 pounds.
How many pallets can you put on a C-5?

    @KCferrari lol You're right there. But the loadmaster would probably have stopped you eventually. Loadmasters are a picky bunch.

    @jamesPLANESii @Sunnyskies close enough lol Not my problem if the plane cant take off XD My theory was if you literally just dump pallets in the plane till u can stuff in no more. You asked how many I can put in, not how many it can fly with :P

    Anyway the solution is 486 pallets. 27 pallet positions carry 10 pallets, and 9 pallet positions carry 20. A ten-pallet pallet weighs 3311 pounds (11 pallets + top net, straps, and dunnage). A twenty-pallet pallet weighs 6355 pounds (21 pallets + full net set, and dunnage. Together you get a total of 146,592 pounds. Theoretically, you COULD put 496 pallets on, but that brings you to 149,636 pounds. But, when you account for all the extra things that typically ride on the cargo floor along with the cargo on a typical flight, it would simply be too much. @KCferrari Came the closest, so I guess he wins! I'm going to bed.

    Fully loaded with empty pallets the C-5 is over 50,000 pounds over it's gross weight. That's the problem. @KCferrari

    @KCferrari VERY close, but a little high. Did you account for the weight of the nets required to secure each pallet, and the three-point dunnage between every stack of 10 and the pallet underneath it?

    @jamesPLANESii Nope. The real answer is much higher. Pallets can be stacked onto pallets for transport.

    @CL4TRP It can be solved with math. And a little extra knowledge.
    When pallets are transported en masse, they are stacked up to 20 high in groups of 10 separated by three-point dunnage and secured with the standard 463L net set. (or in special containers, but those aren't part of this question).
    The trick to the question here is that if every pallet were loaded with 20 pallets, the plane would be over its ACL, so only a certain number of pallets are stacked to 20, the rest are stacked to 10.

    @CL4TRP The 463L master pallet. The backbone of the US's (and other countries') aerial military cargo transportation.

    @Gestour Wrong. Pallets can indeed be transported on other pallets.
    @CL4TRP What?
