Disagree. The told is complicated, yes, but too hard for the students to deal with? Not a chance. There is a lot of discussion in the beginning of phase 3 on what the told means and what the different numbers mean. And lets be serious, there are really only 3 numbers that matter on the t/o roll and with the PMP the go/no-go decision is a lot easier. When I left sheppard in May there was 1 IFF jet and 6-9 UPT jets that weren't PMP. There's no need to go into what the abort criteria in the t-38 are, but I would submit that it's just not that tough. There are plenty of dangerous portions in the t-38 syllabus, single engine approaches and no flap landings come to mind. Do you recommend that the USAF mods all the t-38s with bigger wings so the approach speeds are slower too?
I think a big reason behind the c-model upgrade was to get budding tactical juggernauts potentially going to fighters some experience with a limited HOTAS, HUD, and UFC. I never flew the A-model -38 but I certainly liked the instruments in the c-model and having a HUD made learning to land a little less hair-raising I think. Compared to my hud-out approaches they were much better.
And by the way the new seat still won't work in the final turn if the motors both quit. Something about a -1600-1900 VVI for the first 1/2 makes it tricky to have a seat that works.
