Cheap
From experience, Comply, be transparent, talk to CASA, gain respect and it ends up a lot cheaper that doing nothing, and u end up having good operation.
Sad to see a orgainsation go bad and many good guys and girls have their jobs in limbo.
Im not sujesting to just give in to CASA, but as an operator you have to develop a working relationshio with them, gain some respect, even if that repect is gained through presenting a diffenence if opinion.
