I've written to McMurdo to ask whether or not they are seeking CAA/EASA approval for the product, given that on their website they have a section devoted to aviation use of the equipment.
I wonder what the cost would be for this?
It is the classic example of the CAA's approach for kit. ie they will mandate the requirement and leave it to the market to deliver the product to the specification.
They forget that there is a lead time so, for a period, we are either flying illegally or not flying at all while the market get themselves organised. We also have to junk perfectly serviceable equipment and pay over the odds for replacements.
This is turning into a trial run for the Mode S implementation.......
