Slightly OT, but this raises an interesting point and one of my pet peeves. Why do they list aircraft range in terms of distance? The distance range is so dependent on other things, like winds, load (which is also affected by configuration), altitude, etc. Why not list aircraft "range" in terms of the number of hours it can fly on a full tank? At least it could list that relatively accurately and more precisely.
