Thank you, Pat, for this useful bit of information. It makes me think of the role of safety some more as it relates to metrication. For example, we have the one incident in Canada reported as a mix-up of gallons and litres that (nearly?) caused the plane to run out of fuel. We also have the issue of non-SI units used in aviation here in the States and SI units in other parts of the world. I don't believe one has to be an expert in failure analysis (or wait for a highly publicized collision -- or didn't we recently have one in Europe between that Russian aircraft and another one) to sensibly worry about differing sets of units being used in the same industry or area of commerce. The appropriate governing body could conceivably mandate a change to SI units for all aircraft built in the US so that SI units only would used in communications between aircraft and controllers. But airline companies are consumers. Why not wait for "market forces" to reach the point where the aircraft builders would see the market pressure for SI-only instrumentation and only then switch their gauges, thus inducing the controlling agency to switch the rules because airline companies and their suppliers are pushing for the change?
