Freight DogsFinally a forum for those midnight prowler types who utilise the unglamorous parts of airports that many of us never get to see. Freight Dogs is for pilots and crew who operate mostly without SLF.
It's not a question of fleetsize, but rather one of commercial requirements and profits. Unless your business demands the availability of a nose-door, chances are the 777F will make you more money, as the cost vs revenue delta is very much in favour of the twin.
Using Boeing numbers the 777 burns 25% less/pound than the -800, depending on the operator's procedures of course. There is no doubt the -800 has the advantage when only volume is considered but the 777 is cheaper by far. FedEx flies HKG-CDG, MEM-HKG, MEM-KIX, and MEM-DBX max loads.

I think a loadmaster should contribute to this as I believe the B777F is probably perfect for Fed Ex packets and such. But there seems to be some restrictions when it comes to heavy and bulky loads. For example engines in stands, pipelines etc.
The 777F doesn't have any problems taking engines in stands. Ok, it couldn't take a GE90-110 built up but it can be shippped in fan and propulsor modules. We were also told on training that a 744/748 couldn't take a built-up GE90 nose cowl for transportation also but he aslo came out with some other stuff that we later found out to be "non-factual"
Like you say, pipelines etc are best left to the true nose-loaders like the 744F/748F due to restrictions loading through the side door on others.
But I think that the engines in stands, such as CF6, RRTRENTS, PW4000 ETC have to be on the center line. Unlike B747 where you can have them side by side. The GENX GE90 can have a special rotating stand which is heavy and costs a fortune, but enables them to go through the side cargo doors. You can't beat a nose job for special loads and quick turn around.
The MCD on a 777F is actually the largest in the business, making it quite a bit easier to rotate long/wide objects in and out. The cargo-loading system is computerised, allowing you to place a 16 or 20 footer at a given position, pull a couple of handles and it'll rotate in or out automatically. This goes a long way to reduce interior damage. When it comes to long/thin objects, the CLS can rotate anything up to 9 meters in length in and out of the door.
Here's a picture of a GE90-115 (sans fan) inside a 777F.
used to work it all out with squared graph-paper & a ruler & pencil.
Then stand in the driving rain & sleet & man-handle the built pallet around & over the in-door ball-mat ( 25% of the balls missing, 25% permanently jammed and 25% damn near rectangular). extra points if you manage to get the pallet run over your foot.
Apart from the 14 twin-track and one centre-line positions remaining on the main-deck, as well as lower-decks able to hold around 50 tons, yes, it's quite full.
There's also the not unimportant matter of the 777F main-deck door being 5 centimeters higher and 41 centimeters wider than that of a 747F to take into consideration. I have my doubts a 747F can take a GE90-115, whereas the picture above clearly shows a 777F can. Even if you can get a -115B through the door of a 747, you would have to load it centre-line anyway.
