Re: usage of Mach number (flight related)

> making it difficult to
calculate for a layperson just what airspeed the craft is traveling
at?

a) The typical aircraft has two gauges: one indicates airspeed,
while the other indicates Mach number.

b) It isn't thaaat tricky to convert from one to the other, given
the temperature.

Exactly. Since there is no standard reference, when someone asks me
"how fast is Mach X?" my answer is "I don't know, what's the
temperature/altitude and I can give you a pretty good idea."

Thanks for the clarification.
