If there is enough interest I can sh= ow the full calculation so you can do it yourself at altitude.  I ca= n also expand the interesting part of the chart and put in some additiona= l diagonal lines to allow one to resolve speed better.  Remember: wi= th log scales, the line for 275 mph is NOT halff way between the 250 and = 300 lines.

 

If enough are interested, I will wri= te a little monograph for the archives that has the data on atmospheric d= ensity, simple calculation methods, conversion factors, and all that jazz= so you can do it yourself.
