Non conosco le regole nel mondo dell'aviazione e, soprattutto, della gestione delle compagnie, per cui non riesco a capire questi ordini a "scatola chiusa".

...le nuove sharklet dovrebbero essere alte circa 2mt, (tipo 737NG) e dovrebbero far risparmiare circa il 30% di carburante...

Airbus has completed the first flight of the ‘Sharklet’ wing-tip devices on the company’s A320 development aircraft (MSN 001). This milestone marks the start of the early flight-test campaign to capture data for fine-tuning the flight laws, as well as for certification and performance validation.

Sharklets are around 2.5 metres tall and will replace the aircraft’s current wingtip fence. Offered as an option on new-build aircraft, Sharklets have been specially designed for the Airbus A320 Family to reduce fuel burn by up to an additional 3.5 percent, corresponding to an annual CO2 reduction of around 700 tonnes per aircraft. This reduction is equivalent to the CO2 produced by around 200 cars annually. The wingtip devices will also enhance the aircraft’s performance.

“The hunt is underway for Airbus to take another bite out of airlines’ fuel bills and CO2 emissions,” says Airbus’ Chief Operating Officer Customers, John Leahy. “With this start of Sharklet flight-testing today, actions speak louder than words as we take another definitive step towards greener aviation.”



A standard fit on the A320neo Family, which on its first anniversary after launch has attracted almost 1,500 orders and commitments from 26 customers, the Sharklets will contribute together with the new engines to 15 percent in fuel savings.
