I must congratulate many of you here for managing to divert the thread into a discussion of JAR OPS, the IOC, Swedish alchol limits and whether or not spot-checks of crews are legal. Marvellous, just marvellous.
In the mean time you completely forget to address the main point here, namely why crews time and time again get busted for "driving" under the influence. What exactly is it that drive crews to drink on lay-overs, and why is it that some crew seems to have a problem keeping their consumption to a reasonable level (= a landing beer)?
Few years ago several BA pilots were fired following a TV doc. We may not like the way it was done, or even argue the technicalities of how much exactly they had been drinking. However, for anyone who has ever shared a hotel with a BA crew, it should be obvious what sometimes goes on. Whilst hardly a scientific fact, from own and others personal experience there seems to be a trend. I have seen, on several occasions, BA crews doing all nighters at the bar, only to check out at 06 something ..... Not very fcuking smart.
Alcohol has no place in aviation when duty is drawing close, and anyone in this profession who feels the need to "wind down" by consuming alcohol in quanties that leaves him or her unfit for an early morning duty, is probably in the wrong business.
Time for a radical change of behaviour perhaps? Not suggesting crew should go teetotal, far from it. But abstaining totally from drinking whilst on a night lay-over, and with an early morning report the next day, is probably not a bad idea. Not what aviation used to be like, but times they are changing. This industry is already suffering enough without these stories.
JUST DON'T DO IT!
