Squawkoff,
Congratulations on your upcoming retirement from the ATC sector. Your situation is rather unique and I can't say for sure how you would stand with NJA during the application process but it certainly never hurts to give it a shot. I would say that if you've been instructing in the sim, your credentials may seem perfectly valid, but the best thing to do would be to log some recent turbine time to show you are still proficient and current in the Hawker. We have pilots from all different backgrounds here, mostly ex-121 guys like myself who got chewed up and spat back out by the scheduled carrier world and have no intention of going back. My guess is that they won't turn you down flat as long as you meet the hiring requirements and it sounds like you've got a lot of good material to "fluff up" your resume too. Good luck to ya.
