There is a lot more to it than passing the "regional checkride".

"I understand the legitimate concern that the fast track training program might not adequately prepare commercial pilots to fly, however, that is why for most of the regional airlines you have a to instruct and gain a couple hundred extra hours before getting on board."

If it's a legitimate concern, why do you think it's okay for a "not adequately prepared" new ATP CFI to be teaching zero time pilots? That could be even worse than if they were in the right seat of an RJ.

There is nothing new you are bringing up. This has all been hashed about over and over at this site and at JC. The one common thing I see about 90% of the time is it's the low timers trying to convince the high timers they are wrong about low timers.

Good luck with that. It's no more likely than you being convinced you need to think twice about your views by a high timer. Not gonna happen.

So, I'll leave you with this. Come back to us when you're a new RJ Capt and let us know what you think about having a 500 hour F/O.
