Hi hawk37,

Arrrgh! I'm guilty of typing too carelessly, all of the text stands uncorrected, I meant to type a difference of M0.002 or so, not M0.02! That's quite a difference.

Most noticeable on high flying aircraft like the Learjet, which have a fairly 'fat' wing, and suffer high low speed and high speed drag polars in the mid thirty thousands, quite low low speed polars above 40,000 or so, but the relatively fat (slatless) wing accelerates air to Mcrit rather quickly at higher angles of attack, a good performance in this respect at more optimal angles of attack.

Mea culpa, mea culpa!!!

Regards,

Old Smokey
