Perhaps the solution is to only employ 2000-3000 hour GA operators as a minimum who have plenty of time practicing the landing technique in a 1.2 T aeroplane before they jump into a 28T, completely unforgiving turbo prop. After all, long time GA experience, in a single pilot operation, only doing the annual renewal and "pushing" all the "rules" will colour a pilot in such a favourable way as that they will have the perfect multi-crew skills, procedural and regulatory understanding and compliance, leadership qualities and future management skills that any sound airline would so desire. Above all, this persons many years of operation in light aircraft will provide a more suited candidate to the cadet who has known nothing but airline operation. In no way could this said applicant ever, ever have an incident/accident, or in this case, landing event - I cannot for the life of me recall an experienced pilot ever having an incident or accident through handling error.
It's simply the only way to go about achieving consistent safety records.
As for the aptitude testing, it is clear that it is completely biased toward these highly skilled personnel.
A shame really....
