The Real Message being delivered...
by the UN and IATA's TT is:
The public should get used to the idea of far less experienced pilots up front. Airlines will be relying on the previous generation's captains and flight automation to keep the wheels rolling on the pavement.
Don't believe it can happen? Just look at the US regional industry. Historically at many regionals, it is not just the FO but also the captain that are low experience and sometimes poorly trained pilots. Somehow, the fact that they fly half the passengers of a 737 or 320 makes it OK to have guys up front without a clue. This was even done when there were plenty of experienced pilots available just so that the airlines could lower costs.
Now take this situation, put the pilots in larger planes and remove the relative safety of the US ATC system = recipe for disaster. Incidents like the Air Phil Express A320 off the runway will be a regular occurrence, as will much worse accidents.
Nothing will change until the public demands better from the airlines and their regulators, as was the case after Colgan Q400 crash in Buffalo.
