Yes it's funny how people forget what experience can be gained from GA...
How about "Not being allowed to operate as part of a crew in RPT A/c over +5700kgs, again, where will experienced pilots come from?"
DUH they come from GA... Just like they used to... Right now the goverment could pass legislation that to be be a co-pilot on above 5700kg you must have 1500hrs and the industry wouldn't even blink. Except they may have to start improving conditions...But then again an extra couple dollars a ticket isn't hard...
There are heaps of GA pilots just waiting to get into a turbo-prop or regional jobs with well in excess of 1500hrs...
