Interesting. I know that European METARs report sea-level pressure in millibars with a Q prefix; I didn't make the connection to the Q-codes. In the US we use inches of mercury and we always use QNH on the radio (but it is always referred to as "altimeter"). Something to remember in the unlikely event I ever manage to go flying in the UK. --Ken
