Actually it's Both!
I fly left seat. Ann flies right seat.
Left side of the panel is knots. Right side is mph.
She goes faster than I do, but has further to go.
We usually get there about the same time.

What I use
Personally I use the universal standard of all measurements, the Horse length.
http://en.wikipedia.org/wiki/Horse_length
Currently my RV-7 goes 151,840 horse lengths / hour or 2531 horse lengths / sec, commonly referred to in the industry as HLPS.
Matter of fact, I was racing a B-55 the other day and on the start, he had me by "the slimmest fraction of a nose." However, by the end of the 2 mile course I had pulled head by at least 25 horse lengths. It was at this point that he noticed a dark substance streaming from my aircraft. He radioed and asked what was coming out of the back end of my trusty steed. To which I replied, "It's horse......" Well, you get the picture.

How far across your EFIS screen does a 6 digit speed tape go?

I typically use knots, but when I want to impress someone - I use Smoots. Hopefully Rob and crew will include an AFS update that will allow the EFIS to display in KSPH, SPS or SPM. 190.4 KSPH sounds faster than 175 knots. 3,174 SPM sounds a LOT faster.

Isn't that because the weather observations are done by a certified weather observer (or automated system) that is certified by the National Weather Service? (which uses statute miles)?

Has anyone notice the performance numbers published by Van's Aircraft for our airplanes is in MPH? Hmmmm?
http://www.vansaircraft.com/public/rv-6per.htm
Why would we change what the engineers of our aircraft have determined to be a better unit of measure?

Marketing, its all about marketing.
From the Reno Air Race web site "Five days of racing action. Six classes of aircraft and speeds exceeding 500 mph."
It reads and sounds better than 434.48 knots.
But here, clearly the KNOTS have it. Or is it we have KNOTS.

I think this sums it up pretty well.
Knots or MPH, the important thing is get out there and fly.
