Err, because its nice to know that when the altimeter reads zero one arrives at the ground????? We went to QNH, but obviously our simplistic military minds couldnt cope with that as there were several incidents so we reverted to QFE. What do you mean by 'the rest of the professional avaition'???? Had QFE passed straight away without asking across the UK, France, Netherlands, Belguim so I dont think we are that peculiar. As we are on silly altimetry questions, why dont the Americans use millibars or hectopascals like the rest of professional aviation?????
