Horizontal or vertical doesn't make much difference - they'll both kill you with a sudden stop... AOA was invalidated below 60 knots because it takes a minimum airspeed for the AOA vane to provide a meaningful measurement. This is a common engineering practice - below whatever speed is judged as a minimum for a reliable measurement, the output is labeled "NCD" or "No Computed Data". Similar limitations are on airspeed (typically 30 knots) and Mach (typically 0.10 Mach). Adding "On-Ground" to the AOA validity is a complication and has failure mode implications (and WOW isn't the most reliable indication in the world). As a designer, I doubt it would have ever occurred to me that an otherwise airworthy, flyable aircraft would ever get down to an indicated airspeed of 60 knots in-flight and that was a condition I needed to design for.ure, in 20-20 hindsight perhaps that would have helped the PF to figure out he was doing something really stupid, but the bottom line was that he was not a competent pilot or he would not have kept pulling back from 30+ thousand feet until they hit the water. Had he sat on his hands instead of panicking and pulling full back, the aircraft would have been just fine.
I think I made somewhat the same point as you just did, or at least it was my intent.As a designer, would you have placed either stick to be out of sight of the other pilot...? Hard to believe you would.... In fact, are they? Very, very difficult to believe both Captain and PM would not have at least sneaked a peek. Thanks
