A new round of innovative ATM initiatives in the region has been launched, designed to reduce emissions and increase
operational efficiency. Emma Kelly examines the latest projects.
Asia-Pacific ATM goes green
irst there was ASPIRE – the Asia and
Pacific Initiative to Reduce Emissions
and now there is INSPIRE – the
Indian Ocean Strategic Partnership to
Reduce Emissions. Both are collaborative
environmental air traffic management
(ATM) initiatives with the same goals at their core : to
implement “green” ATM processes and technology, and
reduce aviation’s environmental footprint.
ASPIRE was formed by Airser vices Australia,
Airways Ne w Zealand and the US Federal Aviation
Administration (FAA) in February 2008. The founding
members have since be en joined by the air navigation
ser vice providers of Japan, Singapore and Thailand.
A series of demonstration flights across the Pacific,
conducted with the removal of normal operational
restraints, showed what is possible. The first five of these
flights resulted in 32,386kg of fuel saved and a 101,986kg
reduction in carbon dioxide, compared with normal
operations. Now the partners are busy introducing ATM
environmental best practices into daily operations.
ASPIRE’s sister initiative, INSPIRE, was launched
by Airser vices Australia last year, with a round of
demonstration flights under the project completed in
July. INSPIRE focuses on the Indian Ocean region –
more specifically on routes linking the Arabian Gulf to
Australia ; Southern Africa to Australia and South East
Asia ; and the South-West Indian Ocean to the Arabian
In addition to Airser vices, the proje ct also involves
the Airports Authority of India, Abu Dhabi Airports,
the Abu Dhabi Department of Transport, the General
Civil Aviation Authority (GCAA) of the United Arab
Emirates, Dubai Air Navigation Ser vices, Airport and
Aviation Ser vices (Sri Lanka), Maldives Airport and the
Sultanate of Oman Civil Aviation Authority. The airlines
involved are Emirates, Etihad, South African Air ways
(SAA) and Virgin Australia .
Like ASPIRE, INSPIRE involves a series of
demonstration flights op erated under “perfect” ATM
conditions, which will be followed by a work programme
designed to lead to the daily use of best practices.
“The aim of these flights is to demonstrate the flight
efficiency that can be achieved within the current
Arabian Sea and Indian Ocean ATM environment by
removing controllable ATM system constraints as far
as is practicable. The reduction in emissions that will
be demonstrated by these flights will ser ve as a credible
target level for ANSPs [air navigation ser vice providers]
to work towards,” says Airser vices.
The first INSPIRE demonstration flight was
conducted by SAA on 10 March, between Perth and
Johannesburg , operated by an Airbus A340. The flight
saved 400kg of fuel – the equivalent of ten tanks of fuel
for an averag e-sized car – and approximately 1.2 tonnes
of carbon dioxide emissions, according to Jason Harfield,
Airser vices’ general manager of air traffic control.
Airser vices notes that this fuel saving was achieved on
a route that is already highly optimised in the en-route
phase, with many ATM best practices already in daily
use. “ The savings on this flight are notable because they
highlight that improvements to practices in the departure
and arrival phases of flight can make a notable reduction
in emissions,” says the ANSP.
The SAA demonstration was followed in July by a further
four flights – Emirates operating a Boeing 777 bet ween
Perth and Dubai; an Airbus A340 ser vice operated by
Etihad between Abu Dhabi and Sydney; an Emirates 777
ser vice from Dubai to Brisbane; and a Virgin Australia
flight bet ween Abu Dhabi and Sydney.
All of the flights received unrestricted taxi and take-
off clearance and an uninterrupted climb to their initial
cruise levels, following company-preferred routes within
Australian upper airspace. On arrival, the flights were
provided with unrestricted descents directly to final
approach and the shortest ta xi routes to the gate.
Emirates’ t wo INSPIRE flights resulted in a combined
saving of over 6,250 litres of fuel and more than 16,000kg
of carbon dioxide emissions, according to the airline.
The airline’s involvement in INSPIRE is the latest
example of its efforts to improve its environmental
performance. Since 2003, for example, Emirates has
worked with ANSPs on its flights to Australia to cut
emissions. Over five years, Emirates says savings have
amounted to 9.6 million litres of f uel and 24,268 tonnes
of carbon dioxide emissions.
“ The aim of these flights is to demonstrate the flight efficiency
that can be achieved within the current Arabian Sea and Indian
Ocean ATM environment by removing controllable ATM system
constraints as far as is practicable.” – Airservices Australia

flight between Abu
Dhabi and Sydney.
