i remember hearing that when it was being designed, the B777 had the capability to fold the last 10 ft of it's wing in order to fit into a standard airport slot. is this true? does anyone operate the 777 with this?

also, if the 767-400 cannot fit into a standard slot, why not give it the same thing?

The 777 could be bought with the folding wing option, but no airlines ordered it. I think it took off 22' total, which would be 11' on each side.

I've asked that question myself. Apparently, no airline ordered them, so the design never came into fruition. There was an issue of extra weight, and also perhaps that airlines did not trust the design and feared that half a wing might snap off...

the NAVY uses it continually, under high loads and stresses than any commercial plane.

yeah, but the Navy needn't be as safe as airliners anyway. They are allowed to be about an order of magnitude more likely to crash, I think.

Despite that - if Boeing offered it for an airliner, it is reasonable to assume it was as safe as is possible (i.e. up to the standard of any commercial airliner)

Right again. I heard that the main reason airlines weren't interested was the weight penalty.

The 764 does fit into standard gate boxes, but what I think you meant is why didn't they do that instead of the other aerodynamic improvements...

...and I believe the answer is just like with the 777, weight, cost, and maintenance.

While it's being discussed, can someone define a "Standard" size parking area at a gate? Whether it's actual dimensions or just what aircraft can park there.

The standard gate size for an airliner is 80 sq meters.

I think what UAL747 is trying to say is that the standard gate size is 80 meters square. 6400 square meters area. 80 square meters is something like 30 by 40 feet... tough getting a 747 in there.

Look at, for example, where Delta parks their 764 in SLC. If two of them are parked next to each other, they must skip one gate. Thus, the 764 can't fit into the "standard" gates at SLC.

if they skip gates at SLC, do they at least stick a 737 in there?

They have to skip gates if two are parked adjacent... there's no room in that middle gate for even a 737.

The 80m x 80m box is the largest standard gate size to fit the largest planes, 747, A340/300, and the upcoming A380. There is also smaller gate size for the smaller widebodies then gates that will only fit narrowbodies. You can use the smaller gates for larger aircraft, but you will lose the use of the immediatly surrounding gates while the larger aircraft is there, which is what happened with Delta at SLC.

The 777 folding wing option was offered so that it could fit into a gate sized for a DC-10/MD-11/L-1011. The 764 was also designed to fit into the same gates sized for smaller widebodies.
