Airways New Zealand, New Zealand’s air navigation services provider, is providing a of range service efficiencies, improved procedures, and world-leading initiatives to assist airlines in their quest to reduce greenhouse gas emissions as they fly into and over New Zealand’s 37 million square kilometres of airspace.
This year Airways New Zealand was awarded the prestigious Eagle Award by IATA for outstanding performance in customer satisfaction, cost efficiency and continuous improvement. A big part of Airways New Zealand’s commitment to its customers is based on its contribution to helping airlines using New Zealand’s airspace to reduce their greenhouse gas emissions.
Airways’ estimates of the annual value of the company’s existing emissions saving efforts through efficient vectoring and flow control are in the vicinity of NZ$20 million per year to the New Zealand airline industry.
These existing emissions savings are being realised every day in the skies over New Zealand through the professionalism and expertise New Zealand’s air traffic controllers and their commitment to finding flight efficiencies for every aircraft they control.
A number of new initiatives are playing an increasingly important role in airline fuel economies by focussing on flexible and efficient routing, and further promoting collaborative working practices between airline operators, airport companies and Airways New Zealand.
Among the new initiatives is the development of an online Collaborative Arrivals Manager involving the sharing of real-time information between airlines, airport companies and Airways New Zealand, to ensure agreed scheduling during disruptive weather conditions.
Developed by Airways New Zealand and operational since September 2007, the Collaborative Arrivals Manager system is enabling New Zealand’s airlines to actively co-operate to get priority flights moving. The result is emissions optimisation driven by more effective scheduling, with a subsequent reduction in greenhouse gas emissions as holding patterns in the air and engine idling on the ground are significantly reduced.
User Preferred Routing, which has been operational over New Zealand’s oceanic airspace for a number of years means airlines can elect to fly optimised routes to achieve better flight efficiency through the benefit of prevailing wind patterns, rather than fly fixed city pair routes.
Dynamic Airborne Reroute Procedures means pilots can elect to alter their routes while they are airborne to achieve better flight efficiency through the benefit of prevailing wind patterns. These have been operational since August 2007 in New Zealand and US oceanic airspace.
The introduction of a reduced 30/30 nautical mile horizontal separation standard within New Zealand’s Oceanic sector – a world first at the time of implementation for such a reduced separation standard - is providing for further efficiency and emission reductions for international flights through improved access to their preferred routes and flight levels, with no reduction in safety.
Produced in 2006, Airways’ ‘Strategic Vision of Air Traffic Management in New Zealand in 2015 and Beyond’ sets out the expectations of New Zealand’s future air traffic management system featuring improved safety, greater capacity, and reduced greenhouse gas emissions. Known as ‘Required Navigation Performance’ (RNP), this project sets out a blueprint for the future of New Zealand’s air traffic management environment, by reducing the track miles and designing routes which optimise unrestricted climb and descent, further minimising greenhouse gas emissions.
Airways’ vision of the future and its embraced philosophy of partnership with its customers combine to lead the industry in its approach to future Air Traffic Management development. Airways New Zealand recognises that aviation has an environmental impact and is committed to doing everything it can to limit the industry’s impact on the environment.
Airways New Zealand is the Air Navigation Service Provider for all New Zealand administered airspace. This includes New Zealand domestic airspace and the Auckland Oceanic FIR which extends from the South Pole to 5 south of the equator.
