It's ATP, not AllATPs.
I did the ACPP in 98/99, got hired, then instructed at the SAT location in 99. Had a blast. My biggest piece of advice to anyone: study the Seminole manual that is sent ahead of time. Know it VERY well. Do that, you're golden.
Checkrides are practically canned simply because we used the same DEs repeatedly and knew exactly what would happen. Even when there's a change of instructors, the newbie knows the routine.
If you have any questions, call the main office in JAX. It's basically a bullpen for instructors who are waiting to hit the field, and most are always happy to talk to you.
