Apologies, sometimes my Navy/USMC lingo comes off slightly differently than intended.
I mean guys coming from a platform with a significantly different mission, i.e., EA-6B, C-130, etc... Transitioning to an F-18/15/16 don't tend to pick things up as quickly as a guy going directly into that platform after getting his wings or a fighter guy qualified in one fighter going to another fighter.
Our SERGRADs, equivalent to your FAIPs, tend to do just fine from the few I've seen.
