If you are looking to instruct on "corporate jets" you should contact the Learning Center Manager at the one that trains the type of jet you have experiance on or want to work at. If you are looing at training 121 aircraft contact the Director of Training at the STL FlightSafety Training Center. All the phone numbers are on the FSI website. They will give you straight answers to all your questions. BTW: they do hire "part time" (hourly) as well as "full time" (salary). They are hiring in some programs. Worked for the 24 years total and happy.
