"A380plus is an effective way to offer even more economic benefits and high operating performance", said sales Director of Airbus, John Leahy. The new winglet appears on the fourth A380 test aircraft, on display at the show.
These tweaks introduced by the aerospace firm will allow for "up to four per cent fuel burn savings", as the winglets are created to reduce drag.
The 15-foot extensions, together with other wing refinements, will boost efficiency by as much 4 percent, Airbus said in a statement Sunday, dubbing the upgraded aircraft the "A380plus".
The biggest buyer of the A380 has been Emirates, which have called on Airbus and engine maker Rolls-Royce to provide a new upgraded "neo" version.
Earlier this year, Airbus unveiled changes to the cabin, including packing in more seats, to help convince airlines to buy the plane. This proposal is designated the A380plus, and is meant to increase the aircraft's economics and efficiency while retaining passenger comfort.
People familiar with the matter said on Sunday Airbus was also close to clinching a roughly $5 billion deal with low-priced carrier Viva Air Peru.
Airbus said the cabin had been improved to allow for up to 80 extra seats "with no compromise on comfort" and there's a new wing design which is meant to bolster aerodynamics.
Airbus says The A380Plus will have an increased maximum take-off weight of 578 tonnes, allowing airlines to either carry more passengers over the maximum range of 8,200 nautical miles or increase the range by 300 miles. The existing A380 model has an average capacity of 497 passengers, which could be upped to 575 in four classes with all cabin enablers utilised.
The enhancements, announced on the eve of the Paris Air Show, come as the Airbus weighs lowering production rates for the A380 below one-a-month from 2018 if it fails to secure orders this year.
