Chris,
have you ever received the HUD and does it work without a GRT EFIS?
Does the curvature of many piston GA windscreens make projection more difficult than on car windscreens?

Chris, I am sorry, read this link at the very bottom it says you need a GRT Mini at least. It is obvious as without a GRT Efis where do you get the attitude and air data from.
I was always wondering why Avionics manufacturer are not building the same HUD displays that the auto industry has for years. The HUD in my car is amazing. I see information and pictographic symbols floating like holographs 1.5 meters in front of me. The eye does not need to adjust between near and far. It works in day and night and is crisp, sharp and detailed. There is no ugly frame, like in Chris Parkers first image, and field of view is wide across half of the driver window. It really looks like in the picture below. Imagine an attitude indicator would be displayed like this. It’s just a projector build into the dashboard. What’s holding avionics companies back building this into an aircraft dashboard?

Hope not. According to the page I looked at, only the software is required.
One interesting solution for a HUD focused further away in a SEP aircraft is a laser projector drawing an image on the rotating propeller. You don’t even need the combiner element!
Cool idea – a HUD can give you a flight path in case of an engine out. Ooops…

I’ve now ordered the Hudly Wireless, a development of the one wigglyamp suggested. It wil run the GRT HUD software.
Nope. That one doesn’t give a collimated image, either. So the eye needs to change focus between the image and infinity.
I am a bit surprised that car HUDs does not do that – thy are projecting an image that is focused at around 3m ahead of the screen, why not innfinity? All it needs is a slightly different curvature of the screen, or am I mistaken?
