about 6 months minimum before they’re allowed to talk to real planes, a year and a half minimum after that before they are out on their own. the academy will get rid of a lot of people who truly are not cut out for this type of work, and facility training will get rid of more. tbh i’m not super worried because the job is do it by the book or find another job. if they don’t do it right, they won’t be talking to real traffic for very long if at all
