Most large aircraft do have the capability, by the nature that as a % of their total weight, the fuel is a significant junk. DC-10s/MD-11s, as do 767s, 747s, 777s. Someone visualized it for me that if a large aircraft landed that was almost full of fuel (if it could hold any sort of glide path) would stop when the wheels touched the ground; but the wings would keep going. Boom. Not sure how true that would be though. Matthew On Jun 24, 2004, at 12:44 PM, mgreenwood@xxxxxxxxx wrote: > Not every aircraft has the capability to dump fuel.
