Heathrow Director
I wouldn't set foot in an aeroplane which was about to be flown anywhere near CAS unless I knew that it had a fully serviceable transponder and somebody with a modicum of commonsense driving it.
However you are more than content to provide a safety service with a system that :
Unlike the old primary radar, modern radars do not see flimsy aeroplanes too well
So why doesn't the CAA insist that these modern radars are removed from service and revert to 'old radars' until such time as
all airspace users are equipped with the new systems?
