ASI Scale Altitude Correction

[Genghis the Engineer]

Does anybody have an Excel spreadsheet or similar tool that calculates Scale Altitude Correction for an ASI? (That is, to correct between IAS and CAS).

I need to generate my own, and frankly life is too short to start writing complicated binomial expansions for such things if I can possibly avoid it (and every set of course notes that I own seem to be a photocopy of a photocopy of a photocopy!).

Please?

You're looking for an excel sheet to calculate this graph, right? http://www.aviation.org.uk/pdf/navyFTM108a7.pdf ("http://www.aviation.org.uk/pdf/navyFTM108a7.pdf")

And I suspect you'll find http://www.aviation.org.uk/docs/flighttest.navair.navy.milunrestricted-FTM108/c2.pdf handy.
