Airbus has launched its new "Sharklet" large
wingtip devices, specially designed to enhance the eco-efficiency
and payload-range performance of the A320 Family.
Offered as a forward-fit option, Sharklets
are expected to result in at least 3.5% reduced fuelburn over
longer sectors, corresponding to an annual CO2 reduction of around
700 tonnes per aircraft. 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.
Zealand is the launch customer for the Sharklets which are
specified for its future A320 fleet.
Air New Zealand Chief
Executive Officer, Rob Fyfe said, "Air New Zealand recently
decided to move to an all A320 fleet for narrow-body operations on
domestic and short-haul international routes. 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 added, "Sharklets are not just part of Airbus'
response to addressing environmental issues and rising fuel costs,
but they also enhance aircraft overall performance."
The 3.5 percent efficiency improvement with Sharklets will be additional to the already positive effect of the
A320 classic wingtip fence. Payload-range benefits include either
a revenue payload increase of around 500kg 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 36m) 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.
