A ring sight that shows concentric rings (usually and incorrectly called Newton rings) that move with the wearer's head to stay centered on the target is a complex piece of optical engineering, involving multiple layers of polarizing media ("polaroid") and optically anisotropic media (such as calcite) cut perpendicular to its optic axis. The thickness of the layers is critically important. I doubt that it's an easy do-it-yourself project. (I used to teach this stuff)

Nobody reading this thread has seen you jump or land a canopy. Your instructor has. I suggest you follow your instructor's recommendation.

My Altitrack has started behaving erratically. The battery is fine so it's not that. The digital readouts on the back are OK, but the analog needle on the face goes (consistently) to the wrong place, about 4,700ft, when I turn the unit on. If I remove and replace the battery, the needle ends up consistently around 16,000ft. If I reset the unit the needle goes all the way around the face and ends up consistenly in the wrong place. I have discovered that the following sequence gets the needle to the zero: reset, turn the unit off, turn it on again. It then stays correct for the rest of the day, but after it shuts down, the next morning when I turn it on the needle goes back to 4,700ft ????? ...

Has anyone experience with the Pilot7? And if so, what do you think of it, and the various fabric options? ... The only sure way to survive a canopy collision is not to have one.

Sorry, that is just evasion. An object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. The path over the ground establishes the motion and speed, and the wind shear sets up the unbalanced force. Do the math. ... The only sure way to survive a canopy collision is not to have one.

Explained in great detail in the thread previously linked. And you never answered this question: "What happens if you are flying on a heading of 360 in a 150kt wind from 090 and rapidly descend into a layer of 20kt wind from 090? No autopilot, hands off the controls." Break out your E6B which you probably last used 18,500 flight hours ago and do some vector algebra. And don't forget Newton's 1st Law. ...

When was the last time the wind was constant all the way from opening altitude to the ground? ... The only sure way to survive a canopy collision is not to have one.

NEWTON'S FIRST LAW. Think about it. You may have thousands of flight hours, but Newton has yet to be proved wrong in non-relativistic or non-quantum situations. ... The only sure way to survive a canopy collision is not to have one.

. Nothing to do with that. The vertical tail causes the nose of a plane to turn into the relative wind. So if the relative wind is coming from the side, the plane will turn towards that side. ... The only sure way to survive a canopy collision is not to have one.

But planes aren't designed that way. They have large vertical tails. ... The only sure way to survive a canopy collision is not to have one.
