Vasco,
FJs at KAF use QNH. The FJ community isn't the driver for keeping QFE, although some seem to think it is (e.g. Brize offering QFE to FJs by default). I think the most ardent defenders of it are the instructional community, although as you correctly point out, if students everywhere else in the world can cope with QNH, one hopes that our potential future F35 and Typhoon pilots would also manage!
