I can't understand the aversion to using AoA to control flight in the take-off, approach and landing phases in heavies, airlines, FAA-world. I used it in the T-38, the Citation (same indexer display) and the C-5 (no indexer, but 7 units for approach, from configuring to landing). Not very useful in cruise, I'll admit. An AoA indication was installed on our Bombardier planes, but NO flight-verified recommended indications for any operations. We were told to "let us know how it works and what approach indications are, the FAA won't certify it".
The wing flies on AoA, not airspeed.
