Aand C , A rather unsubtle attempt to highlight your worshipful cat c status eh?
To compare proceedure /trg specific cat 3 airports to the overwhelming majority of airports that the rule applies is a disingenious way to highlight your superior special circling skills.So in this case you are wrong. the airfields you mention are exceptions to the rule. Now wind your neck in and get back to having your bollocks felt at security.
