I was attending a conference where it was confidently stated we were only 15 years from pilotless airliners. I had to pipe up and say "double that". I was challenged and reversed the challenge by pointing out that the statement obviously came from an engineer. This is because engineers have the confidence that they can find a solution to every issue. The FBW Airbus types are a case in point. The engineers design the ECAM procedures for every eventuality they can think of. But there are many more situations they can't anticipate. In about 8000 hours of command on these aircraft, I have had five 'significant' events, none of which were resolved by the ECAM procedures and required the pilot's systems knowledge and analysis to make the aircraft safe. One was a programming error in the Flight Warning Computer software which reported one problem, but ignored a bigger issue. A similar case was with the FWC reporting an issue with a system not actually fitted to our aircraft. Another was an issue with the Navigation System not seen before; another was as a result of a dual failure which the ECAM couldn't resolve (the suggested course of action would have resulted in the aircraft depressurising) and the last was sequence of events which started as an engine fire indication, but led to a depressurisation because of a failure that had not been seen before and which had not been considered in 25 years of the type being in service. This event led to the checklists being re-written.
Until the computers monitoring the systems have sufficient artificial intelligence to evaluate and make decisions based on the information presented, we are a long way from certifying autonomous systems in public transport. I certainly wouldn't get on one of those aircraft, and I suspect many would feel the same. And even then, I wouldn't trust the AI!
