no prob Charl, read and taken as one
Not worried, as the way they keep changing the plan I'll be lucky if my grand children are not working approach before any of it happens!
forget about the current 05L/23R. It was only ever a temporary conversion of the taxiway for use while the works take place on the main runway. It is far to close to 23L/05R for simultaneous ops and the cost will stop any approach aids being installed on it. The same goes for Cat3 on the northern runway - too expensive for both installation and maintenance for the return they would get from it. Will prob only be Cat1.
Last version of the plan I saw they were wanting to go directly to the mid sized length, able to take B737 sized aircraft, etc. This would make sense as the majority of traffic can handle that sized strip. Most of the trans tasman stuff is B738/A320 size and by putting them off the other runway it frees up room for the heavies.
If it was done logically you would have a full length runway built and then depending on wind you have all arrivals on 05L and departures off the current 05R or all arrivals on current 23L and deps off 23R. No extra noise to the north. The only bug bear is going to be the missed approach protection with departure stuff crossing north/south etc further out.
Will be interesting to watch - if they don't decide to turn it all into shopping malls and carparks first!
