JO, may I suggest that, in response to a problem, you are putting up an Aunt Sally of a wrong solution?
As many have suggested (myself and several better qualified people), what was needed was better training for the eventuality of “Otto” handing it over as it could not cope.
If pilots have no training or practice in hand flying at mach 0.8+, and FL 350+, and none in UAS at such levels, it is not surprising that it can go wrong.
We have also pointed out the poor CRM, lack of adherence to SOP and/or QRF, which to my mind also suggest inadequate training and testing.
AF, and/or the industry, and/or the regulators/ICAO, need to look at these issues and change things for the better.
