Aviation Sunglasses Revisited

Recently I've had the opportunity to try a pair of Coloreyes sunglasses with the smoke grey tint, and found that I quickly got used to them.

They are a bit darker than my Randolphs, but I found that the increased colour contrast made up for this, preserving visual accuity, although I do have to take them off earlier in the evening than the Randolphs. They also have more of a curve to them, meaning that less light can get in from the sides to cause reflections. The effect these glasses have on colours is very different from other glasses; they make reds and blues look more saturated, while leaving colours in the middle of the spectrum (like green) more or less untouched.

Solving the wind triangle is the only non-trivial math needed by the private pilot. Unlike weight-and-balance or speed-time-distance calculations, which are just simple arithmetic, the wind triangle requires trigonometry. At least it would require trigonometry if you didn't use some sort of flight computer, either electronic, or one of the traditional "whiz-wheels".

When I first began my flight training, we were all required to purchase an E6-B style flight computer. This has a circular slide rule for speed-time-distance and density altitude calculations on one side, and a graphical wind triangle solution on the other side. This style of computer is manufactured by several companies, including Aero Products Research and Jeppesen.
