Also note that the creature's manueverability largely affects how it can move when not flying in a straight line, i.e. turning. It takes a certain amount of movement to turn with certain manueverabilities, thereby limiting the total distance the creature can cover. Of course, as with running, you can't 'run' while flying and turn, as you have to 'run' while flying in a straight line.
