PBL:
Further, I want to know what exactly is wrong with the causal analysis we presented a decade and a half ago in that paper. I don't see any mistakes in it. If you can't find mistakes in it, they you haven't refuted it adequately just by saying you disagree.
Link me to your paper and I will read it carefully.
My issue is squarely with relating their misuse of the FMS, auotflight, and navdata becoming in any way a liability for anyone other than American Airlines, and only in the context of their agents' inept operation of the flight. The analysis of the FMS was fine to point out limitations of which the crew should have been aware. But, some of those limitations still exist today; hopefully all crews understand them better.
I was a "pioneer pilot" on the 767 having started training in 1983 and flew it unil April, 1986. We reverted to raw data periodically as a matter of staying proficient in all of the options.
