There is a similar debate running in the Rotorheads forum about the future of AOC operations for the rotary world.
Seems a lot of people are pretty hacked off with the extra red tape involved in running a PT operation (and thus needing an AOC)... and wondering what, if anything, the CAA/EASA plans to do about the amount of leasing / sub leasing / fractional stuff thats going on!
Watch this space over the next year or so - I would imagine they shall have to do something.
