yeah , I'm thinking small planes here, like a 172 or something obviously airliners would have to physically change out the altimeter. I guess I was just thinking that when I do a cross country flight here , every time I get new info you change your altimeter to the reported setting from the local info , getting it in one set of units and having to do the conversion "on the fly" would be a pain.
Yep, most people with a working knowledge of Canadian aviation history have a good idea of what happens when you get the fuel conversion wrong. Gimli Glider .
