I just googled EAS. So are you referring to the sports nutrition product, Energy Action Scotland, Employment Agency Standards, the European Athletes Society, European Astronomical Society, or are you just throwing in an acronym for the sake of it?

The graph in the book is a simple demonstration of relative turning circles. It's not scientific. It's very 'layperson', but not necessarily 'wrong' per se.

I'd say the altitude is a typo. The x and y axes obviously show the same parameter, i.e. radius of turning circle in feet. But I have the book, so I'll check if it's clarified in the text.

EAS is equivalent air speed, Crumpp will be along in a minute to teach you all about it....

Ah, thanks Bongo. I did guess that really. Bit of facetiousness I'm afraid.

However, I checked the text and there is no clarification as to the methods of calculation re the turning circle. It's a simple example for the readers of a book who don't have PhDs in aerodynamics. Or even a GCSE come to that.

But this doesn't make it 'wrong' per se.

It does just mean sea level.

You would have to understand that True Airspeed at Sea level equals EAS.....

I know...

Why do you assume I don't know that? I am merely trying to clear up some confusion on what the figures on the left side of the graph mean...some people seemed confused by it's meaning....

Maybe some experts will be along to tell us how wrong it is to use EAS??

LMAO!!!!!



Thanks Milo, you are so predictable in your zeal to prove me wrong!


your zeal is eqally as predictable.

It is scientific and all my calculations agree with the results. Unfortunately, radius of turn is not the best indicator of actual turn performance.

Because your statement is contrary and wrong.

My interpretation of the graph is that that bot the left and bottom figures are radius (note how the lines intersect exactly the same figures on both) and the note on the left just means 'sea level', no EAS or IAS involved, admittedly it is a very badly designed illustration.......what's the big deal?
http://forum.1cpublishing.eu/showpos...&postcount=107

It is cut and dry and requires no interpretation. You are just plain wrong.

That is why anyone would assume you don't know that True Airspeed equals Equivilent Airspeed at sea level. If you did know, then you are just lying about it in your above reply.

The performance is radius of turn in EAS.
