Located in the mountainous, fast growing, tourist resort area of New Zealand’s South Island, the Queenstown airport requires special high accuracy procedures to guide aircraft on their final landing approaches under instrument weather conditions. But first, they must descend around the local mountain range. There, Airways New Zealand has selected a multilateration surveillance network to allow air traffic controllers to closely monitor the safe descent flight paths of arriving aircraft prior to their landing approaches and, later, their departures over the same challenging terrain. “Multilateration provides coverage in difficult terrain areas, which was the basis for Airways’ recent investment at Queenstown,” said Ashley Smout, CEO of Airways New Zealand.
