I wonder how this will impact the tailhook pipeline. Most of the Phase I (intermediate) syllabus was just learning how to handle the speeds and handling characteristics of the T-45. I'm sure they could get rid of some of the instrument sims, and formation flights, however I sure wouldn't feel comfortable stepping into the Phase II syllabus without confidently knowing how to handle the jet. I felt I got everything out of the T-34 before stepping into a Jet. The T-6 will only be able to provide so much before needing to jump into the next platform. Sure, the Instrument phase would have been nicer in a slower aircraft with all those bells and whistles, but that faster speed is the main obstacle in the early instrument phases.
It used to be that guys who selected jets would move on to the T-2 and learn the jet flying and instrument flying techniques, then move on to the T-45/A-4, so it might not be that big a change from how it was done. When they were talking about changing it to the current system, they talked about flying the T-34 at 1015 for most of the approach to get the same basic idea (faster flying), but eventually decided to go w/ the way they have it now.
Penetration approaches are flown at 250 knots (usually at idle + boards for parts).
Your standard GCA box is flown at 200 in the early stages... 250 on downwind once comfortable/instructor discretion.... Slow to 200 once on base, gear, half flaps, slow to on speed (usually 120-140 depending on fuel state).
The "problem" I see w/ this plan is the transition period. There's going to be a lot T-34s around while the B comes online, so while the stud can potentially be pushed farther if you use the plane as a jet transition, you're going to have to find a good place to do it so you're not running into traffic ahead of you. And that's not even considering the problem of the box pattern at Whiting where the guy in front of you may be struggling to maintain 80 KGS.
I know it's on the "list," but they really need to get that PAR up at N. Field and a lot of problems could be eliminated.
