It is a little unnerving people with so little experience will potentially be 2IC with so many lives in their hands. In terms of being in control of such a large aircraft with its various systems, good training can completely take care of that - after all, military trainees are doing their first PC9 solo after 5 hours on type, after 60 hours in a CT4. The Army dudes are going first helo solo in a jetranger after about 8 hours.
What does concern me, as said before, is the lack of
experience in dealing with crap weather, emergencies, diversions etc - the kind of thing all the best training in the world can
tell you about but not necessarily
expose you to. Its this exposure that comes with experience, previously gained on much smaller aircraft with much smaller consequences... Bring back the bug smashers
