Real dangers to airsafety.
We all agree that nobody should fly a plane under the influence of alcohol.This applies to any other profession which involves the safety of the general public.
However in the case of airline pilots there are many more factors that can reduce performance other than alcohol and to label a pilot unfit to fly just because he had a drink the night before, is more of a danger than any misleading alcohol test.
Hidden factors such as tiredeness, depression, stress, mood swings,etc can compromise safety just as much if not more than alcohol, but these are not measurable using technology and are nevertheless very real factors.
If a pilot doesn't drink any alcohol but stays up all night, surely he is more dangerous to the airline and the public, but because this is not measurable noone is penalised for it.
Safety rules are a fundamental part of our societies, and your industry in particular, but common sense should also prevail.
If this specific BA pilot had only a drink (still to be proven) the night before the flight, it would be a crime to label him a drunk, as the media has done, as this could potentially ruin his career without any "real" foundation for disciplinary action.
It is only the extremities of the Swedish law that have bought this situation to the public attention and laws are made by falable human beings.
I am not a pilot, but I feel this is a case of following the letter of the law too severely, in this particular case a law that is almost impossible to implement because of its extreme severity.
Asking people to drive at 5mph normally doesn't result in them doing so because it is almost technically impossible to do so without stalling. In the same way this rule goes beyond the limits of common sense and doesn't contribute to better safety at all.
