I teach in a RJ AATD and King Air sim as well as classroom stuff at Saint Louis University. When they were losing a bunch of instructors when hiring was good, I offered to help out part-time. Then they said they may be getting an RJ AATD and that using me as a CFI probably wasn't the best for both parties. It's worked out great. Teach Monday/Tuesday, fly Wednesday/Thursday - Saturday. Drink Saturday night, sleep Sunday.
