I must admit to having seen some excellent ATC work in recent days from TWR controllers. Getting departures away with four miles between arrivals. It's been pretty to watch.
I'll admit to having seen the occasional clanger (being asked to taxi as number 2 to Thai out of PER the other day was one of them given that we could have been airborne before he had reached the holding point given his slow taxi speed) but these things happen from time to time with the best of intentions. More often than not it's been great work and far better than I've experienced in most places around SE Asia.
If we could go to an system such as used in HKG, LHR, LAX, etc for SYD airport then it'd be great. One runway for arrivals, the other for departures.
