Thank you for an excellent source and reply. I found this in the UK CAA manual: "The following words may be omitted from transmissions provided that no confusion or ambiguity may result: d) 'Millibars' when giving pressure settings of 1000 mbs and above" It then gives examples: Pilot: "G-CD maintaining altitude 2500 feet Wessex 998 millibars" ATC: "G-CD descend to altitude 2000 feet Borton QNH 1000" www.caa.co.uk/docs/33/CAP413.pdf Here are some voice transcripts from ATC elsewhere in the world: "QNH Habsheim 1012 Fox Echo 984" http://catless.ncl.ac.uk/Risks/9.86.html "Independent Air one eight five one roger you're cleared to three thousand feet on QNH one zero two seven and ah runway will be one niner." http://dnausers.d-n-a.net/dnetGOjg/080289.htm
