More importantly, I would be wanting to know why the FO didn't take over control of the aircraft. I'm surprised the TOI didn't ask that question in the article.
I wonder what policy AIX has to resolve crew conflict. I know one former carrier of mine, there was a 2 call policy. If the CA did not respond by the second deviation / concern call-out, the FO had the legal support of the company to take control and assume the CA as incapacitated.
Wish more places had such a policy.
