G’day Duane,

Howdy Paul,

I am afraid you are both missing my point.

I shall try to express it in such a way that my friend Grayhawk (see – I even use your American spelling to conform) might be suitably impressed – eschewing obfuscation, notwithstanding.

You can calibrate your ASI, or buy your car speedo calibrated in fingers and toes if you like. But the fact is, you are no longer operating in an American vacuum.

Numerous ( that is, many) posts are viewed across the world by pilots – owners builders etc, who live outside the shores of your great land, and who conform to the convention of KNOTS in terms of aeronautical speed measurement.

And many ( that is, numerous) posts are proposing certain performance parameters, or formula etc, and I’ll bet my brass b****s that most American Lancair drivers watch their ASI’s calibrated in the global convention of aeronaut-iggle speed measurement of – KNOTS.

So when someone from the from the great land of the bald eagle posts performance numbers in terms of MPH, or FINGERS and/or TOES, it is meaningless because, as I have already explained, had explained by one of your countrymen for whom I have great regard, that such terminology may not appear to be what it actually states. AND as I have tried to get across in previous posts in this matter – when you refer to performance numbers such as stall speeds, well, it is important we all know what is meant.

To explain further, in this country, lots of car drivers –usually brash youth, like to brag about how many “KNOTS” they have achieved in their hot rod, when in fact they are reading their speedo in KPH, and before we had KPH, in MPH.

Yeah Yeah Yeah ! I know lots will think it is trivial.

But – you can choose to join the real world, or………………

Best regards

Dom
