I was wondering if anyone could tell me the main reason people washout. In other words, what separates those who CPC from those who washout?
From what I've seen so far: attitude.
The most important thing is that people don't mind you being around. That doesn't mean crack jokes and introduce people to your awesome personality, that means keep your mouth shut.
Beyond that, some people just can't do this job.
Coming out of the academy you're probably not going to be prepared for what's in store for you. Trainers usually operate according to this motto: train to rate, write to wash. They don't care if they hurt your feelings and they will think less of you if they do.
Don't expect anything better than "No assistance needed," or the local equivalent on your training reports.
Don't talk back, ever, but do ask questions during debrief if you're unsure about something. Treat your trainers and tower cab/dark cave with reverence. Don't talk about non-ATC things in the tower unless spoken to by a trainer. Stay in the books. Don't brag at all. Don't stick up for other trainees - it will make the trainers think you're more loyal to the trainees than you are to them.
Training is all about making your trainers comfortable with working with you which means you have to...not suck, do work and remain clear of the pain in the ass tag.
The bottom line is you're getting paid to train. Do your best to assess your short falls and ask a trainer if they agree with what you think is a problem during debriefs. Never tell a trainer about something you think you're doing well, even during debrief. It is okay to, if you're not busy, ask your trainer if there was a better way to handle a given situation if you're unsure about it.
Work your traffic like your trainer would, even if that means having 6 different ways of working your traffic.
Focus on learning your operational priorities and learn your phraseology to a point that you don't have to think about it.
Operational priorities are key and by operational priorities I mean: who should you be telling to stand by, who should you be taxing and where should you be looking.
Operational Priorities are probably secondary in importance only to Voice Quality.
If you don't sound like you know what you're doing pilots won't listen and neither will trainers - that means they're going to assume you just suck instead of listening for things you're saying wrong.
No one is going to give you the benefit of the doubt.
Oh yeah - Laugh at yourself when appropriate and don't kiss ass. Controllers hate ass kissers.
