It's one thing for a back-up to rely on AOA. You've already got system degradation and you're now in the "continued Safe Flight and Landing" element of certification, where the assumption is that we're simply trying to recover the a/c to any safe base. It's a whole other thing to plan flight on that basis. How are you going to respect MMO/VMO based on AOA? It's almost impossible, because depending on weight, VMO will be a different value.
Again, your T-38 LANDINGS were on AOA. How did you do a descent from cruise alt? I'm willing to guess, not by reference to AOA.
