CJCAP...
You hit the nail on the head. JAX was the strongest location because we required you to have a full brain to pass a checkride. As an Instructor in JAX, we had the opportunity to see a great many students from the other locations as they came through for COM/CFI training. The farther west they came from, the worse they generally were. Mind you I said GENERALLY, there were some shining exceptions. Sometimes we wondered if you guys used the same checklists, procedures, etc. out in the western locations.
Since the coorporate office was so close, management could and often would stop by, which added an extra bit of motivation to those instructors not already inclined.
I could go on and on... ATP is an excellent choice, regardless of where you go. I have many good friends at locations around the country, but JAX will always be a step ahead.
Also, about our examiner, I suspect you busted a ride with him- join the club. He is still an excellent teacher in his own way, more than fair and refuses to put up with mediocrity, from the students or the instructors.
The JAX airspace??? There isn't a more accomodating ATC group anywhere that I know of.
I joined a great many ATPers at TSA. How bout yerself? Take care!
