Do you think that has something to do with your eyes being horizontal?
Take a picture and see if any part of it is blocked by the bar. Your visibility IS BEING BLOCKED.

And no matter how much your head or eyes move, the picture remains the same. But that's not how it is in the cockpit. I'm always looking around that "protective" bar..............that's so cool in numerous ways.

If you take a picture it is the same as looking with one eye, so yes it is blocked in all views. But since we have two eyes, the verticle parts don't block the view.

I just did some more tests, if the verticle obstruction is wider than the spacing of your eyes, you can not see through it. If it is smaller than the spacing of your eyes (2 5/8 inch for me) you can 'see' through it.

I don't understand how biplanes are able to fly around in the sky and not run everyone over with their obstruction :-)

The average car has more visibility blocked than a slider canopy.
Its about the experience of flying without a barrier infront of you.
Its an expereince. Hence why some of you with fantasies of being fighter pilots have the experience of being in a fighter cockpit and that is more important to you than anything else.
For some of you like Louise, its about being free as a bird so ANY obstruction defeates that mental state.
Some like to be in the machine and some like to be in the sky and that is what I think drives this argument.
No ruler, eye distance, head bobing, airplane pictures are going to out do either the bird or fighter pilot fantasy.

I like the slider because I can do both in it, and I do.

Each eye has a blind spot that you never see because one eye compensates for the other in that location. Now block one eye and the remaining eye will have a blind spot that will hide an aircraft.

I could see how you would not understand the visibility of a tilt up. You really need to experience it to understand. Kinda like riding HWY 70 through Utah on a motorcycle without a helmet compared to sitting in a car. You will still get there........ but you missed so much.
It takes me about three minutes to clean and polish my canopy........ even a few bug splats take away from the experience.
It's all Van's fault!
