Can't disagree with you ACW, if only to ensure 8 hours sleep since I suspect not enough sleep wll degrade your performance more than a small amount of residual blood alcohol will, regardless of the legalities.
The reason that I did the research which led to that post (and yes Monocock, I did cut and paste from something I had on my HD - I can type that fast, but not whilst making sense at the same time) is that I was getting worried about the number of crude rules of thumb doing the rounds, and just wanted to know the scientific reality of alcohol and flying. Took me about 3 hours in the Royal Aeronautical Society Library one day whilst waiting for an afternoon meeting.
I tend personally to take a similar view of all professional activities. Anybody working for me has never been left in doubt about my views of lunchtime drinking - bad decisions made in an engineering department can still kill people, they just take longer.
