Hi Scott
I was the one demonstrating the proposed Tower Head Up Display which answers my two basic operational requirements - 1 readable in bright sunlight - 2 does not affect field of vision. Maybe I should put this on the site as an additional forum subject. I will be demonstrating the latest model at ATC Maastricht next year on my own stand as I retire to take over a friend's consultancy company. I'll probably see you in Washington DC at the ATCA show in November.
The web site I mentioned on the previous message will also include the HUD for controllers to comment upon.
The stuff we design is "designed by controllers for controllers" with assistance from other necessary expertise.
