Innovation Analysis Group has a 15 minute podcast with Aviation Partners, which revealed that they are working on winglets for the Boeing 777–with a prediction that the product could be ready for installation within two years.
This follows the winglets for the Boeing 767, which Aviation Partners suggests will provide a 5%-7% fuel burn improvement.
If a similar improvement is made for the 777, this will close the gap between the 777 and the projected fuel savings for the Airbus A350. Airbus projects a 20 operating cost savings over the 777, although we recognize that the remaining 13%-15% advantage still is nothing to sneeze at.
Aviation Partners is also working with Airbus, though AP declined to discuss it. It’s known, however, that Airbus and AP are getting ready to test a winglet on the A320 family. AP did discuss the prospect of winglets for the A380–which would be 17 feet tall. The wingtip fences on the Airbus family are old technology, AP says.
