QNH 1000 - digit by digit or 'wun tousand'?
CAP413 says that altimeter pressure settings must be transmitted digit by digit, but some of the PPL texts say that 'QNH wun tousand' is OK on the radio and apparently this is due to a UK exemption.
I would have thought CAP413 would list this exception though. Anyone know the definitive answer to this (and where it is listed?!)
