Ah, the mist clears I can see now why I was in a muddle, there was talk in the patent of moving dots to indicate roll/pitch and I've confused this with the Lightnings flight director indicator. I would guess the roll/pitch dot idea wasn't followed through to operational instruments.
Hence why I was trying to figure out the 'dots' relative movement to the horizon display during attitude changes, which was a complete misconception. I can grasp the nadir/zenith star concept so I should now be able to finish that part of the project.
I really can't imagine what it would be like flying something like the Lightning, I get worried enough in a PA-28 at 2+G
