I realize the above can be a bit confusing and overtly technical, so don't hesitate to ask what the heck it means if in doubt. We've got a gaggle of engineers here and between those guys and a few other technocrats surfing the web, I thought a few people would "dig it"

It looks nice and fancy.

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...

Yea I can't read that .

What we teach though, and what I've learned, is that a bank actually help Vmc AND performance, by eliminating, or lessening the sideslip factor that you get in level flight

I think Va in the B55 is like 180mph... which is pretty high for a light twin. It's really hard to power back to 180mph at sea level... I've seen 19'' still hovering around 190-200...

If you power up that Baron and dive... it's pretty clean so it'll pick up speed quick. I'm not sure if I would have powered up that engine... but maybe powered down the other one.

Either way it's hard to play Monday morning quarterback... I can honestly say I've never been inverted in a light twin. One good thing about the Baron is that it has an unusually good, responsive ailerons so I imagine the "roll rate" is pretty good for a light twin with neutral power.

* as an off topic rant.... Everyone says the B55 is a fuel guzzler... it's really not, you can honestly get around 11-12 gal/hr a side ('bout 22 total) and still true at about 200.

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.

I know it is and like I said, most of us don't know it. The average person probably knows theta equals an angle and V represents velocity. Beyond that your chart is useless for the majority of readers.

You said, "don't hesitate to ask what it means." Well in its current form I suspect maybe a handful of readers actually know what it means. So instead I gave you a way to simplify it.

Instead of telling me all of the terms go back and replace them with one word titles. Math is such a simple structure to learn, but we lose everyone because we refuse to use the english language and instead expect people to learn a new one. It is no wonder people are literally scared of math.

If anything at least define the terms and rewrite that formula with those terms defined in [] as I suggested. Watch how something that right now might as well be in chinese suddenly becomes readable to the majority.

If you wish to not do it, don't. However, the reply you just made probably took as much time as it would have taken to replace each of those terms and make a currently useless presentation useful.

Disclaimer: I am not meaning to be harsh or disrespectful. I am sure it has very useful information. However, in it's current state it might as well be written in chinese.
