I'm a fan of the metric system (kilos &c) - the result of studying a science subject (chemistry) to degree level. Aviation is a technical industry and should use 'scientific' parameter measurement. Markjoy - you ATCOs often instruct us to 'turn left 15 degrees' or similar. We manage to work it out without too much trouble. Feet & pounds are just very old-fashioned and illogical (like uniform hats). It's not anti-Americanism - the US invented aviation & has led the world in aviation technology. They just need to start thinking like Europeans!
But I accept I'm probably in a minority (of one?) here.
