Now for the constructive criticism. Of those reading this, I suspect maybe a percent understand it in the current format. I think a simple removal of greek letters and replacing them with the a one word term would be far easier to read. It is only simple algebra, but the laymen like myself can't read it because it's basically written in a language I don't know.
Something like (and this is not correct): [yaw] = [weight] * [velocity] * [air density] / [pitch] * [thrust] with the columns marked appropriately to match. IMO that would be far more beneficial then the current format.
Otherwise, it looks pretty...
The Greek is there because in writing equations, a place where things get figured so precisely, there isn't enough space for it and math is not a verbal domain. However you point out something that is spoken of at length in Langewieche's books on flying. He say in so many words that understanding runs along many tracks and that mathematics is only one track of several, which is true. So we talk but if we really want to understand all there is to know we must also learn the mathematics and only then do we have the complete picture. In the end however, math is merely another human language among many, and one that lends itself to precision, so the balancing of many things at once can take place. If it would help I can translate the variables, up to you. They are found in all flight dynamics textbooks.
As far as what the chart shows, see how things come together? They are not random at all, it is a very organized progression converging with speed and diverging against it. The unseen mover here is the three equations of motion for the aircraft. I'll start a thread on that next time maybe, or you can.
