HN39
Sorry, you missed the point of my post, which was twofold: First to point out that Jane's sonic speed was for 273 K, not 288.15 K (hence the title: Confusion?), and second that the standard sealevel temperature is 15 °C per definition, not 15.2. Thought that would be obvious.

I see your point HN39 and I do apologise. UA

Sure, I can be odd, and be socially inept, kind of quirky sometimes
I wouldn't have thought that. However, you have livened up the forum somewhat with a bunch of interesting questions and you consistently keep the threads stirring along nicely. As to whether that is because you are just tenacious or have medical conditions with long names is beside the point ...
Those who might find your style irritating are not forced to attend class - the others of us probably find the threads more than a tad interesting.
Solution: Use a text editor.
Neat trick - I shall remember that.

TAS = Mach * a0 * sqrt (T/T0)
EAS = Mach * a0 * sqrt (P/P0)
Which rather appeals to my sense of symmetry.
a0 = 661.48 kts
T0 = 288.15 Kelvin
P0 =1013.25 hPa
Then all you need the ISA stratosphere pressure equation and you can generate CliveL's lookup table.
