I'm sure some on here will have a better idea of manning in the NAE, but I know PERS has been playing with people's orders lengths both for first sea and first shore in order to create enough time prior to MSR to get them a Super JO tour. I would imagine this is being done to plug what they see as a short term gap in the VTJs/FRSes and then a longer term gap in the fleet.
I think the difference is that the Navy plan (as the MCG is written) would be making T-6 IPs with only ~100ish hours of first pilot time in military aircraft, period. Whereas FAIPs at least go through T-38 or T-1 training before going back as T-6 IPs. Maybe this program is meant for guys with significant prior civilian or NFO time, but as a guy that did well in the T-6 syllabus, I will tell you that I would have been nowhere near ready to safely to fly with a dude just starting out in the pipeline, let alone instruct him/her in a constructive manner.
