Alcoholism is problem of society..pilots because of our professional needs have to free of alcohol... I genuinely believe no pilots attempts to be drunk before a flight ...The first time you get caught should be enough of a warning for your conscience...The second time .. Shame on you... One chance should be given second one i think is a no no ... Punishments vary worldwide >We had a case where a f/o doing command training turned up sozzled for sims The instructor promptly stopped his command training and made sure he reverted back to f/o status ...If you get caught the shame and the time off should be good enough... Second time ....
