Dick, that's why I like the simple dive test. There's no math to study when you're in the sky and the dive test takes all the factors into account in a very simple and easy to allow for way.

While I really like studying the theory you'll note that I seldom take part in the heavy math parts. While I understand the need for the math and applaud those that take this on like a favourite cross word puzzle challenge I just can't wrap my grey cell around it unless I have to and it's reasonably simple. But I sure do enjoy studying and discussing the basic principles.
