Depends on the center if you can work part time or not.
At FSI Savannah the only way you can work part time is if you were once a full time Instructor. Even then it's up to the center manager.
Pay is different at all centers. At Savannah pay starts at 70K with most Instructors making 80k up to the mid 90s. (More titles equal more pay. ie do you teach intial, are you a check airmen etc...)
All Instructors have to get 85 DALs (Instructor client face to face time) per month. Gulfstream Briefs and Sims are 7 hours so as you can see you only have to work around 13 days a month to make your time required.
Some months are busier than others. Usually we only work around 10 days in December, July and August but in May, June, September and October you may have to work 16 days. We do work about half the weekends but we almost never work late Sims here at the Gulfstream Center. The Gulfstream clients pay a lot of money and WILL NOT do late night Sims (ie 0000-0400). It all works out to be a pretty awesome job.
I just did hear, from our Center Manager, that turn over is so low that the company is ending the pension plan for people hired after 12/31/2005.
We also get 10 holidays, 2 personnel days and 2 weeks vacation (years 0-4), 3 weeks (years 5-14), 4 weeks (15-19), and 5 weeks (20+). That's why all the old guys hang out here. They all get 5 weeks vacation, make 95k a year and also get a Flight Safety monthly pension while still working here. Just check out the Flight Safety Employee parking lot looks like a Cady, BMW sales lot.
