Hi Kurt,
You might want to call either MITAGS or PMI (
www.mitags.org or
www.mates.org). They've got some really good AIS / ENAV instructors that could talk with you. I'm thinking specifically of Steve Burtchael and Jorge Gutman from PMI.
Doug Pine, PMI Instructor, is on this board every now and then, maybe he can comment?
Good luck,
Fran
