Aerodrome classifications
Hi BOAC. The runway width thing is code as in aircraft type. ICAO code D means the bigger passenger jets, and is usually 45m for runway width.
It is a bit confusing between all the codes and categories. I don't think it is the one here, because Australia had a whole big thing changing from GAAP to Class D airspace for the parallel runway airports, but I've been caught before and am always open to correction.
