Ed, I think you left out a 1/2 factor, see my analysis attached

Bill Schertz
KIS Cruiser # 4045

So, unless I've screwed up the math badly,

it does indeed appears that indicated airspeed provides a fairly

good indication of mass flow at any reasonable altitude provided we are not so

fast as to encounter compressibility.
