For perhaps the only time I find myself in agreement with most of smokies post. i must take exception to the quotation in Airbubies post-surely we are the most tested. supervised,overseen, pestered profession in the world.
Althought there is no specific remit in the AME for alcolhism to be looked for, the first symptoms of system failure will be picked up . which is more than can be said for drunk surgeons, ATC controllers, cannabis ridden civil servants etc.
I agree that self test should be made available--the resulting problems if any could be dealt with by airline management on the same basis that 'tactical sickness' is a problem without involving the draconian remedies apparently proposed by the double thinking bureaucrats.
