That's probably right captjns. But it will be ever so much more fun to give the co-pilot the formula and the calculator and ask him to find the SAT from our mach number and our OAT/RAT reading, then explain about the 10% of IAS thing after!
Actually, I'll try both tomorrow. Then I'll compare the results to the SAT/TAS reading on the air data page. Gotta do
something during cruise, and this seems both safer than, and preferable to, allowing any further discussions of religion or politics to commence!
