[QUOTE="TechGrrl, post: 586284, member: 4932"] That's basically true: 1 feeder door being worked is approximately equal to 1,000 PPH as a rule of thumb. So for a pure feeder door sort, if you have 30 doors being worked, that's 30,000 PPH. Because of shifting needs, you would probably need 35 actual doors to keep that up for a sort. During the twilight, you would also have the package cars being unloaded. I could be mistaken, but Louisville Worldport is the only hub in the system that has no package car drivers assigned to it. The package center moved off airport property last year to a site about a mile south. The actual capacity of a building is more complicated, since any flow system has a bottleneck that throttles the actual flow capability. The calculation of this bottleneck is highly dependent on exactly what is going on at any one moment, and is why flow balancing from the unload is critical to a smoothly operating hub. Aren't you glad you asked? :happy2: [/QUOTE]
