As part of the ongoing process of introducing ATM best practices on a daily
basis, user-preferred routes (UPRs) were recently launched between Melbourne and
Auckland by Airser vices and Airways New Z ealand. UPR s, whereby operators use the
most efficient route rather than following fixed, published routes, are already in use by
some carriers across the Pacific Ocean and in the Indian Ocean between Australia and
the Middle Ea st and South Africa.
Since June, airlines flying between the two cities in either direction have been
able to use UPR s, increasing efficiency and reducing emissions. Airser vices plans
to introduce UPR s on all ser vices across the Tasman Sea and eventually across
continental Australian airspace.
The routes are calculated by an operator’s flight dispatchers with the aim of achieving
a minimum-fuel, minimum-time or minimum-cost flight.
“Airlines will be able to make these decisions based on factors such as forecast
weather, aircraft type and performance as well as their own scheduling requirements,”
says Mark Rodwell, Airser vices’ acting general manager of air traffi c control. “This will
enable them to fly optimised routes to achieve better flight efficiency through the use
of prevailing wind patterns, delivering shorter flight times, reduced fuel consumption
and greenhouse-g as emissions.”
Elsewhere in the region, the Civil Air Navigation Ser vices Organisation (CANSO)
launched a pilot project in July, designed to improve ATM efficiency on one of the
region’s major air routes – bet we en Bangkok and Singapore – through the use of
collaborative decision making (CDM).
CDM improves the exchange of information between all stakeholders involved
in flight operations, including airlines, airports, ANSPs and government agencies.
CANSO says the project will provide the information needed to enhance g ate-
to-g ate operations, eventually expanding to the optimisation of “kerb-to-kerb”
operations. The pilot project will demonstrate the efficiency gains from the use of
CDM at Bangkok’s Suvarnabhumi Airport and Singapore’s Changi Airport and
the integration with en-route CDM.
CANSO says Bangkok-Singapore wa s selected as there are relatively few air
traffic constraints that could hinder the identification and further development
of best practices. The project team is defining a concept for the pilot proje ct
and exploring practical ways of implementing CDM. CANSO hopes that data
collected in the pilot project will allow the development of CDM implementation
best practices for other city pairs in the region.
Meanwhile, in the Philippines, Airbus’s Quovadis unit is developing a
performance-based navigation (PBN) network at 11 airports in co -operation with
the French Civil Aviation Authority (DGAC) and the Civil Aviation Authority
of the Philippines (CAAP).
PBN, including required navigation performance (RNP), is an ATM concept
endorsed by the International Civil Aviation Organisation (ICAO), aimed at
improving efficiency while increasing airspace capacity and safety. RNP uses
satellite navigation and the latest aircraft technologies to allow an aircraft to fly
accurately defined and contained trajectories, without relying on ground-based
navigation aids. The procedures improve safety, at the same time as reducing
fuel costs and carbon emissions through the use of shorter tracks and reduced
Airbus says the entire region will benefit from the increased ATM capacity and
reduced emissions, making Philippine airspace one of the most advanced, PBN-
optimised ATM environments in the world. The project will include procedure
design and obstacles data sur vey training as well as training for air traffic controllers
and flight-safety inspectors.
“This unique alliance of authorities, air navigation ser vices providers and
operators, which include Philippine Airlines, Cebu Pacific Air, Airphil Express
and Zest Airways, is a true breakthrough in the industry,” says Paul-Franck Bijou,
chief executive officer of Quovadis. “ This project brings together all stakeholders
to create fuel efficient, flexible and safe trajectories.”
