This request is sort of intermixed within others but, I would like to plan fuel stops with automagic help while still on the ground. This would require a small amount of plane profile data, including size of tank, normal fuel burn rate, and how much fuel is in the tank after a fillup. This is especially helpful on long xcountries when your legs are as short as mine. Planning fuel stops is entirely math driven an is extremely tedious with current iFly capabilities, requiring actual use of pencil and eraser and paper.
