Airbus announced on Sunday at the Dubai Airshow that it would offer winglets for its A320 family aircraft starting with an order from Air New Zealand in 2012 that would improve fuel burn by 3.5%.
Boeing first introduced winglets on its Boeing Business Jet in 1998 and commercially in 2001.
Airbus claims that its new “sharklet” A320 winglets will best Boeing’s 737-800 in relative fuel burn by about 9%.
