Two more rapid exits will only help for those that occasionally miss the existing ones, international heavies and for some reason Air NZ A320s
so wont have a huge benefit, not to mention the cost of building them. The missing link cost 10 mill and look how long that took.
2 min arrival spacing sounds great. But it only gets you an extra 5 landers per hour (max). Not enough room for heavy departures, and no doubt more go arounds.
Adding a finals director is a great idea and is badly needed. However at this stage the Brisbane Terminal group is only hoping for enough staff to open Brisbane Departures North. Sometime in September. So unless, following all the negative publicity on the efficiency of BNE Airservices make it a priority to expedite the training of two extra positions in the near future I wouldn't expect a lot of change rapidly.
