I'm with SND ( Cheers, "Two Six"

I've done a whole load of flying over Norway and Sweden operating from countless aerodromes where there was often nobody on the wireless to read out any numbers. A QNH from a local-ish big airport was obtained by listening to big stuff and ATII, and paying close attention to terrain and aerodrome elevations. Aerodrome Elevation is far more important than any 'QFE'...
