UP recoveries = on the head down attitude indicator. The HUD laddering effect when pitching quickly makes it relatively usless to assess pitch angle.
AoA still works fine - pull to the limit and get the nose above the horison!
VV I don't care about since the vector is changing so fast at high pitch rates
Designing a HUD that does not relate to the horizon seems a good one to patent on 1 April for use by the swiss navy! You really will have to explain how that could be of use
