WELL,
Reading all the comments, be it scientific to the Nth degree, or the various home spun philosophies, or the holier than thou brigade, I can see that a breathaliser should be part of any Piolts pre departure kit.
People quote the 12 hour rule and my earlier comment amount the amount 12 hours before was (perhaps!) an exageration but it is obvious from the comments that people have no idea whether 2 glasses of wine, 2 pints or 2 scotches 12 hour before will put them over the limit.
As has been pointed out we are not talking about someone falling over drunk but someone who is outside an arbitary limit ( and yes I know about all the scientific committees but it is still arbitary ! )
WE know we are exceeding the speed limit because we have a speedometer but in this case most of us have nothing to judge against.
YES I know the answer if for all pilots to be teetotal ! Perhaps it will soon be a requirement to get a CPL
