I have a friend who is currently taking ground-school flight classes here in Saskatchewan. He's just a couple of years younger than me so he also belongs to Canada's first metric generation. He told me that he was quite upset with the whole idea that aviation in Canada (and North America) was still done in Imperial units. He told me that they're still using miles, nautical miles, feet, "and even inches of mercury". Though he did note that one speed gauge listed "mph, knots, and km/h". He also noted that since most of the other people, who happen to be "much older" than he is, were completely comfortable with these units while he had to learn a whole new language. I'm well aware that foot elevation and knot speed are still used in North American aviation, but I was under the impression that Celsius temperature and bar (or hPa) pressure was being used. Could someone update me on the status of American/Canadian aviation units. greg
