Air New Zealand Will Purchase First Aircraft With New
Winglets
Airbus has launched its new "Sharklet" large wingtip devices,
which it says are designed to enhance the eco-efficiency and
payload-range performance of the A320 Family. Sharklets, which are
offered as a forward-fit option, are expected to result in at least
3.5 percent reduced fuel burn over longer routes, accounting for an
annual CO2 reduction of around 700 tons per aircraft. Airbus said
Sunday that the A320 will be the first model fitted with Sharklets,
which will be delivered around the end of 2012, to be followed by
the other A320 Family models from 2013. Air New Zealand is the
launch customer for the Sharklets which are specified for its
future A320 fleet.
"Air New Zealand recently decided to move to an all A320 fleet
for narrow-body operations on domestic and short-haul international
routes," said Air New Zealand Chief Executive Officer, Rob Fyfe.
"The new Sharklets will enable our Airbus fleet to benefit from
lower fuel burn and carbon emissions, both across Air New Zealand's
domestic network and especially on the longer trans-Tasman
sectors."
Airbus Chief Operating Officer - Customers, John Leahy said
"Sharklets are not just part of Airbus' response to addressing
environmental issues and rising fuel costs, but they also enhance
aircraft overall performance."
Airbus claims that the 3.5 percent efficiency improvement with
Sharklets will be in addition to the already positive effect of the
A320 classic wingtip fence. Payload-range benefits include either a
revenue payload increase of around 1,100 lbs or an additional 100nm
range at the original payload. The Sharklet installation also keeps
the A320 Family within the ICAO 'Class C' (wingspan less than 118
feet) and will result in higher available takeoff weights, notably
from obstacle-limited runways. Moreover, where runway performance
is not 'limiting', operators should profit from a reduction in
average takeoff thrust (with consequent savings in engine
maintenance costs by around two percent), while communities will
also appreciate even lower takeoff noise. Other benefits are the
enhanced climb performance and higher initial cruise altitude.
This latest development has been part of the larger continuous
improvement program for the A320 Family which is supported by an
annual investment in excess of $150 million each year. To this end,
Airbus has conducted a thorough campaign over several years to
evaluate improved large aerodynamic devices - not only using
Airbus' company-owned A320 test aircraft, but also with its
advanced computational-fluid-dynamics (CFD) simulation-tools.
