I like metric as much as the next guy but you can pry knots from my cold, dead hands.

You may add feet for altitude (you fly in levels that are in hundreds of feet, like FL300 is 30000'. In meters you get to fly separations of 300m which can be much more error prone).

I've flown to Moscow dozens of times and the altitude in meters is much more confusing(even if you only use it now below the transition level, from 0 to 3000'), the wind speed in m/s you may get used to, but Knots is much better for all speed units (also the mach num aproximately corresponds with NM/min, example 0.80 Mach is 8 NM/min.)

Your cold hands, Fahrenheit or Celsius? ;)
