Thanks again, Now I think I'm starting to get a clear picture.
So, in essence, what some of you are saying (in a jet) is this:: Best L/D speed for a given weight would give max range, but because the engines may not work as efficiently at this lowish speed, a better mileage per pound of fuel is obtained at a speed somewhat above that of best L/D. Is that it?
What I didn't understand was the post by toffeez. What did you find so scary about my post 6, which, after all, was only another question? Was it that I asked a stupid question?
