Wings Think you may be a bit out of date, Temazepam, in the form of 'Normison' was used by RAF pilots during the Falklands war and was also approved by the CAA, only to be disapproved when it was realised that the drug 'hung over' in the system too long. That is what I have been told, anyway!
Also agree with AI and Khan, Zimovane is, I think you will find, the approved substance of the day.
There must be an AME out there who can confirm/deny?
