When you leave AMF if you are able to get past the toxic attitude they have and teach their instructors then maybe, yes.
FSI does not have a 100% pass rate either. I don't know where you get that notion. At my last company we had probably 10% of the guys fail their Lear type in Tuscon.
My 100% comment was paraphrasing your original "close to 100%" statement. I take offense to this toxic attitude bs because I bust my ass to instruct (yes, teach) the people who come through the doors here. Most of us do, and from the stories I've heard about this place, I don't blame the attitudes of the former employees.
That being said, I wouldn't characterize it with blanketing statements for the current staff. We understand that it's an introductory 135 company for a lot of the new hires, and take it's not going to be beautiful sunshine and meadows in the sim from the start.
If I see a basic lack of instrument flying skills, manifested through numerous sims, then we have a problem. It isn't just flows or call outs, a lot of it is the basics. Where do you draw the line at instruction? How many additional sims can be given to bring someone up to the level needed to send them to basic line training? It's not an easy call. Would I like to see everyone who comes in through the door pass? Absolutely, and most of us here do whatever we can to help. At a certain point, though, it becomes evident that some people just aren't cut out for it. Say what you will, but I stand by my company's training. Now I'm going to go hydrate with kool aid.
