Look, like BigBear said, I'm not going to buy into saving an extra 69# of gas per mission when we are flying empty I would guess at least 25% of the time. I've seen countless times flying from the states to some place in SWA with 18 pallets and 69,000 pounds of stuff, then going back with absolutely nothing when i know there is something within an hour or two that need to get back to the states. And don't get me started with the types of crap that we haul to these locations... last trip I was on we flew at least 12 light carts to this undisclosed location when I can almost guarantee they have more than enough of them there already, but since the ones there aren't for the unit that is deploying then we have to haul them out.
From what i've seen from the MIF software so far is the same that we've been doing before in the C-17. Fly 2-4k below max altitude and M .74... slower if you have a tailwind and faster if you have a headwind.... got it... we had a checklist that told us the exact same thing in the past. We already have enough to do from alert to takeoff that this is just another hinderance.
Instead of this program, we should have hired fedex to teach us to run like their shipping model. I guarantee we would save more fuel that way than this program. Just my .02.
