EVERYONE we fly with uses nautical miles ... because that is what is on all the charts.
Where would one get charts with statue miles? AAA

You have no idea how hard it is for an English guy to admit that anything invented in France is better..

I do love this forum!

So Larry, just how many buckets of popcorn have you enjoyed since stirring this pot up, eh!

And "nobody cares about how fast a ship goes"?...I dunno, how fast the carrier was going made a fair bit of difference in the "quality" of the air behind it (more natural wind = less burble), so we cared how fast it was going! (We also cared how fast it was going when it was headed into port! )

Hey Mike, all those Class B, C, D, Mode C, etc rings and things on charts (and yes, in GPSs too)...what kinda miles are those in...hmmmm

So there are a lotta knots out there...the only ones I don't like are the ones that get in my headset cord...pesky dern things!

MPH sounds good to U.S. race fans (500 MPH Unlimiteds and 400 MPH Sports does sound pretty cool, ya gotta admit)...and it sounds good to U.S. airline passengers (they'll get there faster...and happier...at 500-600 MPH...yessir!). If you're quick, or do it 6-10 times a day (outbound and inbound...AMHIK), you can convert KTS to MPH on the fly, just like C to F temps, which we also have to do, since C is on the paperwork, but is still a mystery to most folks here (and as Bob Ax said...we were going to be converted by 1975!

If you really want to brag, state top speed in MPH, and stall speed in KTS, then you win on both ends! Don't screw it up though!

And have you guys forgotten? Girls like knotty boys...so what are ya thinkin'!?!

Cheers,
Bob

The serious answer is one talks to ATC continuosly while flying IFR, speed comes up quite often (either cus there is a Cessna put put in front of you or a jet behind you) and your better off using the same language.

As an engineer that is fluent in both metric and Imperial units, I have to say the metric system is by far the best.

You have no idea how hard it is for an English guy to admit that anything invented in France is better..
The American (Imperial?) system is an engineering pain and a mistake waiting to happen for anything involving mass because it uses the same units for mass and weight or force.

It's January, cold, windy, a little "cabin fever" setting in. This is what happens when there is no build in the shop.

" No one cares how fast a ship goes!" Did I really say that? . I was in the Navy, yes we cared.

We have been debating this for some time in another group and it spilled over into this one as an after thought. Just having some fun.

Your fun was taken seriously by the majority of VAFers. How come nobody uses metrics? I heard one favoring Mach but the unit was not in the poll.

Hey, we decided this issue years ago, right here on VAF. Everyone was happy with the Mock System.

100 mph = Mock 1....cocktail party bragging rights for RV-12 owners.

200 mph = Mock 2....routine for the rest of us, although -9 owners really should fix their static system leak.

300 mph = Mock 3....used by a small group of Rocketeers, or the airport liar.

Question A question...

All the reasons for using knots are valid. However, I use MPH because that is what every plane I have piloted since I started flying in 1968 has the ASI in MPH. I was instructed in MPH. I don't fly IFR, and the guys I fly with use MPH.

Does anyone know why, if knots is the standard for aviation (charts, ATC, ect.), it seems virtually all civilian aircraft made in the last 50 years have ASI's in MPH? It seems like the manufacturers should have used knots, but they didn't. Or would that be an option when the plane was manufactured and the buyers selected MPH?

Vlad! Everything on VAF is taken seriously...Larry saw a Saturday Night Live opportunity and took it. Proud of you Larry! Of course everyone is right because the airplane doesn't care and soon they will all be flying without pilots anyway (we just get in the way). And yes, the metric system is used in the states by the US Army...just ask any grunt what a klik is...and always has been.
