I dont understand why you are worried about refocusing? From what I have heard and seen (not much, actually), the HUDs in the fighter planes are focused at infinity. I cant imagine a fighter pilot flying at Mach 2 worrying about changing his focus. Doesn't the fighter pilot just look where he's going and there's the data??
