Sort of like an aviation chart with nautical miles shown between stations? I guess it makes sense to use knots then.

Knots for speed because that how the ASI reads and what ATC uses to tell me what the wind is doing, feet for altitude, litres for fuel (we're in Australia), millibars for atmospheric pressure, psi for tire (tyre) pressure, miles for distance (should be kilometres), deg centigrade for air temperature, deg fahrenheit for the engine, etc ....

Aviation must win the prize for the most bizarre set of units of measurement ever devised

Seriously? I did not know that! When was the last time anyone used a paper map? Do they still make them?

Hybrid knots and MPH. I always refer to groundspeed in knots, and airspeed in MPH. I learned to fly in Cessnas which had MPH on their ASIs. My Cherokee that I flew for 10 years was also in MPH. Every taildragger I flew (C140, Cub, Supercub, Citabria) and learned tailwheel flying, was also in MPH. The RV-4 that I really learned how to fly RVs in, was also in MPH. My friend's RV-8 that I currently fly has a Dynon D-100, which makes it easy to change back and forth, is generally always left in MPH because the owner prefers it that way too. I've just gotten accustomed to learning all the airspeed numbers in MPH and old habits are hard to break. The RV-6 I'm looking to buy has steam gauges, and its ASI is in knots, so I guess I'll just have to learn a new set of numbers if I do end up buying that plane.

The ATC system uses knots. That is good enough for me. It makes things nice and simple when they assign you a speed or ask your speed.

The military use knots. The airlines use knots. ATC uses knots. Team RV uses knots.

You can use furlongs per fortnight in your own airplane. Use knots only if you want to fit in.

Virtually every single reference to speed and distance in every aeronautical document, chart, sectional, AIM, FAR, not to mention every controller uses nautical miles.

It's the unit for the system. Anything else is just for bragging rights.

I use mph when bragging about the speed of my 6 to my nonaviator friends just so I don't have to explain the difference between mph and knots to them but use knots when with my aviator friends and talking to atc. And even they ask me mph or knots? May be easier to use mach. "I was cruising along at .23,..." sounds good.
