Is any of this a problem? Are you sure you're not just making it into one?
Recently, when flying in France, the friend I was with asked me if I wanted the QFE (she was doing the radio calls as she lives there and her French is better than mine). I said I didn't care, so long as I knew which way I was doing it. She seemed to think this was a perfectly normal way of thinking.
Either ask for the QFE, or do a quick bit of mental arithmetic. Neither is a big deal, for pilots or students or anyone with a half a brain. Why does this even get discussed?
