The second half of this paragraph is pretty damning summary of the performance of the stick-holder (I can't even call him a pilot).

> In a July 2011 article in Aviation Week, Chesley "Sully" Sullenberger was quoted as saying the crash was a "seminal accident" and suggested that pilots would be able to better handle upsets of this type if they had an indication of the wing's angle of attack (AoA).[264] By contrast, aviation author Captain Bill Palmer has expressed doubts that an AoA indicator would have saved AF447, writing: "as the PF [pilot flying] seemed to be ignoring the more fundamental indicators of pitch and attitude, along with numerous stall warnings, one could question what difference a rarely used AoA gauge would have made".[265]

I think there is a high percentage (probably a majority) of 15-hour, pre-solo student pilots who could have broken the stall of AF447 well above 30K feet.

Another reference that goes a little more into it, but short of reading the official report: https://degreesofcertainty.blog/2019/05/08/air-france-flight...

> The pilot at the controls that night was Pierre-Cédric Bonin. Although he had clocked up many hours in an Airbus cockpit, his actual experience of manually flying a plane like the A330 was minimal. His role had primarily been to monitor the automatic system. The time he had spent manually flying would likely have been focused on take-off and landing. So, when the autopilot disengaged, because ice crystals had begun to form inside the air-speed sensors in the fuselage, he didn’t know what to do. The fly-by-wire system downgraded itself to a mode that gave Bonin less assistance. With the safety net gone, the plane was now liable to stall if conditions allowed, and Bonin inadvertently proceeded to create those conditions.
