I understand that, uniquely among aviation regulators, the CAA is required by UK Goverment to make a 6% profit ('return against investment') including the cost of the hanging gardens of Gatwick.
The last time I visisted, it was so occupied they could easily operate out of a couple of Portacabins in a lower cost part of UK, solving their liquidity and our cost problems at a stroke.
Their plea to EASA to put into place rules to prevent 'regulatory shopping' fell on deaf ears. I suspect their days in the present form are numbered as they become unaffordable - remind me of the cost of an IR test in (a) UK and (b) Belgium?
