FL - thanks again!
In the wonderful world of JAR-land, as they've given specific meanings to 'will', 'shall' and 'should', I was merely trying to use the same convention! Which is why Devils Advocate's company's Ops Manual is interesting - in JAR-speak it states that he mustn't start a flight duty period with more than 20mg/ml, but only that is
recommended that he doesn't have
any residual EtOH in his bloodstream. Thus 21 mg/ml would be in contravention of his company's manual, but 19 mg/ml wouldn't.
Happy Humbug-tide, m'lud!
Incidentally, when travelling as SLF I'd be far more concerned at flying on that (non-Irish) lo-cost with well-reported exhausted pilots than ever I would at flying on an airliner with a pilot with a 20 mg/ml BAC...
