Just put second officers straight into the right hand seat, easy! 150 hours is all you need, the equivalent of 1.5 months of a current KA captain's roster, that's more than enough.
Soon you will be able to go from abinitio to LHS widebody on "learnersworld", in your own time, at your own pace, just remember to print out your license before you log off or there will be an entirely new set of questions next time you log on to upgrade to captain, assuming you have completed 3 consecutive months of line operations.
That shortage will never come, experience requirements will probably drop now that we are asking for a lofty 150 hours and a hong kong ID.
Do we really need a hull loss or two to address this? It would be sobering for our passengers to know that most of our frequent flyers have been in an aircraft many more times than one of the pilots up the front. I'm sure that's not what they feel they are paying for, a training creche.
