ATCs, through considerable experience of unstable approaches, are advised not to offer the southern runway to traffic inside 30NM from touchdown. The ideal is 50NM, but practically it is very difficult to forecast the departure queue at that range.
Most CX/KA guys I've spoken to would happily take a optimal southern runway landing within 10miles. Anyway to change the above philosophy? It's rather frustrating going down 07L in a freighter seeing no one land or depart until you're half way down taxiway V having requested 07R 30miles out, even to the point of discussing we should request a visual sidesteps while on final (unusually clear day obviously). Can we give early (50nm) notice that we are willing to accept a intercept heading runway change? Which happens in Taipei quite often after a runway inspection is complete or is opened while on a base intercept heading.
