Tell me airtrafficers, why is it some airfields like LHR seem to be able to use speed control as a method of tactical planning, where as other airfields when queried, say they are not authorised to use speed but must use headings to achieve spacing whilst feeding the ILS? Is this some legal thing or a special rating for ATCO's.
Hacks me off that some airfields make you go around the houses wasting fuel even when you offered to slow down and go more direct and they say bog off! What do we do?
