Thanks for the answers, setting standard when cleared to a Flight Level and leaving the standby on QNH makes ultimate sense to me. As for the US procedure of resetting it as you pass through transition Alt that was the jist of my question...anyone know where the actual requirement or procedure is written down. On departing New York, cleared to FL 330 from well below the transition I was critisised for setting standard as other aircraft below the transition and descending would be on QNH.
