In 2011, based on an estimated 63 flights per we ek,
approximate savings on the routes for the year will be in
the order of 2.47 million litres of fuel and 6,850 tonnes
of carbon dioxide, the carrier says.
According to Airser vices, the Arabian Sea and Indian
Ocean is a “distinctly different air traffic environment”
to the Asia-Pacific region and as such the INSPIRE
programme faces different challenges from ASPIRE. A
particular focus of the flights involved reducing ATM
constraints in the north-west of the Indian Ocean.
The demonstration flights also ser ved to successfully
extend the existing Australian Organised Track
System (AUSOTS) programme that has seen the
implementation of flex tracks. The flights involved the use
of two flex track s at the same time between the United
Arab Emirates and Sydney, with each track provided by
the participating airline.
“This is a significant evolutionary step in moving
toward the target-user preferred route environment,”
says Airser vices. There are no plans for further
demonstration flights, the ANSP says, with the
partners now confirming the emissions savings ahead
of developing a programme of work that will lead to
these savings b ecoming daily practices.
INSPIRE’s sister programme ASPIRE has already
reached that stage, with the launch of the daily programme
earlier this year, whereby ATM environmental best
practices are monitored on a daily basis.
Prior to the launch of the daily city pairs, the ASPIRE
programme saw six demonstration flights, with the latest
conducted by Thai Airways with a 777-200ER in May
bet ween Bangkok and Auckland, marking the entry of
Aerothai into the ASPIRE partnership.
On averag e, the demonstration flights conducted
by Air New Z ealand, Qantas, United Airlines, Japan
Airlines, Singapore Airlines and Thai saved 234kg of
fuel per flight.
These demonstrations were followed by extensive data
gathering and performance modelling , paving the way for
environmental best practices to be used on a daily basis
on selected routes.
The first ASPIRE daily city-pair was launched
in February between Auckland and San Francisco,
followed by Los Angeles- Singapore. Additional daily
pairs have been identified and the next, bet ween Sydney
and San Francisco is due to come on line in September,
coinciding with an Asia-Pacific Economic Cooperation
environmental summit in the US city. At the same time,
Los Angeles-Melbourne will also become an ASPIRE
daily city pair, says Airser vices. The eventual plan is to
have a net work of “green routes” throughout the Asia-
ASPIRE daily city-pair flights operate under optimal
flight plan conditions utilising user-preferred routes,
dynamic airborne rerouting procedures, 30/30nm
separation in the oceanic environment, time-based
arrivals manag ement, arrivals optimisation, departure
optimisation and surface movement optimisation .
“Of critical importance now is to g et the attention
of airline passengers,” says Doug S cott, chairman of the
ASPIRE partnership. “ They see g overnments imposing
environmental taxes on long-haul flights, yet what they’d
prefer to be seeing is an industry taking active steps to
reduce its environmental impact. That’s A SP IRE – a
network of partners across the world who are collectively
committed to implementing world’s best practice in
ATM and environmental stewardship – every single day.”
“Of critical importance now is to get the attention of airline
passengers.” – ASPIRE Chairman Doug Scott
Etihad is processing the results from its INSPIRE demonstrator flight.
