I think QFE is a British-only thing (the RAF uses it)
To the best of my knowledge you're right here, I don't think it is used anywhere else, except in the ATIS in some Spanish airports (e.g. LEMG) with a very high level of British traffic.
METAR LOAV 141200Z 14012KT 5000 BR BKN006SC 04/03 Q1012 OVC
METAR LOAV 141300Z 14012KT 5000 BR BKN006SC 04/02 Q1012 OVC
METAR LOAV 141500Z 13012KT 5000 BR BKN007ST 04/03 Q1013 BKN
What does confuse me slightly, however, is the format of the METAR for LOAV, more precisely the SC and ST at the end of the sky condition group. I cannot find any explanation for these. Can someone explain and/or provide a link ?
