Knots
Use Knots. It is the standard. MPH is unprofesional, and braging

No!! Not what Larry said.... knots are what have always been used in my world and thats the way our charts are made. I don't ever feel the need to explain anything to non-aviation types who don't understand the difference - it doesn't matter. Just say "it's about the same", because as far as they are concerned it is. Just say that that is the way we do it in aviation. One nautical mile is equal to one minute of arc at any lattitude and equal to one minute of arc of longitude at the equator. One degree is 60 minutes or 60NM of lattitude anywhere or 60NM at the equator. It actually means something when you reference an aeronautical chart - or your gps lat/long. Statute miles is for lesser earthbound beings. Nascar likes to reference mph because it's good for advertising. When ATC asks you or assigns you a speed, they are talking knots. When you shoot an instrument approach, you are dealing with nautical miles and knots on timed portions of the approach. You can get a plastic 'ruler' that reads both from Sporty's to break it down if you're using a sectional, but why make it so difficult? Pilots use knots Drivers use mph.... if 60 mph is your min safe speed over the fence, then use 60K instead - you'll be safer!!

I'm old-fashioned. I recall that the first airplanes used MPH, so that I what I have my instruments set to use.

And yet ...
The metric system is the standard in the united States as determined by Congress L-o-o-o-o-o-o-o-g ago. They have spent a fortune to make us convert to it for many decades and yet we still commonly use the English system. Strange isn't it. The only thing it has achieved is force me to buy more wrenches.

MPH for me. In training I used knots and Nautical miles. Once training was completed, I bought an old airplane, 69' Cherokee. Only had MPH. Sold that and bought another old airplane, 65' Mooney. Again, only MPH. 500 hours in planes using MPH, so I'm still using MPH. IFR is not in my interest, so no need to worry. :)

The average 6 foot tall male has about a 3 foot stride. In the example of a mile equal to a thousand Roman paces, their stride had to be 5' 3" long!! And YES.... that would require some very tall legs.
BTW......... How did the 201 Mooney get it's name? |

I learned to fly in beat up, slow, old planes marked in mph. The only other plane I owned was old and slow and marked in mph. I associate ASI's marked in mph with old and slow. It's a source of pride having a plane marked in knots that easily gets into 3 digits! Knots for me:D I also find it makes more sense with the charts and ATC.
