You must put in a formal complaint if you do not consider the current system to be acceptable. Mr Skidmore waves away any suggestion of problems with AVMED on the basis that there are so few "formal complaints".
CASA is completely indifferent to the stress you suffer in not knowing whether you'll win or lose from the bureaucratic lottery that the AVMED system has become. Their livelihoods are protected, so they don't need to care. All in the name of "safety" of course.
