As the headline says.
The stupid single taxiway system around the terminal that has planes taxiing from one side to the other and the amount of stand delays due to traffic on the single taxiway is pathetic, it was completely unavoidable you'd think with designing an airport with a clean sheet.
If anyone saw the series
BBC Two - Airport Live at one point you hear them talking about how fantastic it is to have the "toaster system" a rectangular terminal,
two taxiways, rectangular terminal, taxiway, terminal, taxiway, etc. They make a point on how easy moving A/C from one side of the airfield to the other is and vv.
Yet I see the HK airport in all their wisdom are going to do it all again with the third runway, don't these idiots consult ATC or pilots to discuss the layout of the taxiways and the best way to move A/C from one side of the field to the other, look at the convoluted routing they've created exiting off the new runway.
Future Development - Long-Term Development - Airport Layout Plan - Hong Kong International Airport
At least they didn't follow this idea.
However the benifit would be a new CX city and hotel from a clean sheet which is another well thought out disaster.
