Please remember a landmark judgement made by an employment tribunal in favour of the CAA a decade or so ago: although the CAA has a duty to follow and consider current medical practice and knowledge in setting standards and restrictions, it is a valid defense for them to claim they havent the time or manpower to revisit, review or amend existing regulations even if the medical evidence demonstrates their position is wrong
Since then their financial predicament has become ever more precarious so I am sorry but suspect you havent a hope of getting this changed
