Blended Winglets Save Up To 500,000 Gallons Of Jet-A
American Airlines and Aviation Partners Boeing (APB) announced
this week the first revenue flight of a Boeing 767-300ER with APB's
Blended Winglets, days after the winglet installation received
Supplemental Type Certification from the FAA.
American Flight 78 left Dallas/Fort Worth International Airport
Sunday, March 8, at 8:35 pm with 204 passengers onboard and arrived
ahead of schedule at London Heathrow Airport on Monday, March 9, at
"We are pleased that APB chose to partner with American to
develop and install these Blended Winglets, and we are especially
happy that we also operated the first flight with customers onboard
a winglet-equipped 767-300ER," said Bob Reding, American's
Executive Vice President - Operations. "The fuel savings and
emissions reductions that we will achieve are one more step in our
efforts to both moderate costs and shrink the impact we have on our
environment - two goals that go hand-in-hand."
The increased lift provided by the winglets, without a
corresponding increase of engine power, improves fuel efficiency.
Each airplane equipped with the winglets is expected to save up to
500,000 gallons of fuel annually depending on miles flown,
according to APB.
American plans to install winglets on its entire 58 aircraft
fleet of 767-300ERs, which could result in a total savings of up to
29 million gallons of fuel per year. That represents a significant
potential increase to the 111 million gallons of fuel that American
currently saves through its Fuel Smart efficiency program.
In addition to the fuel cost savings, this 767-300ER fuel
efficiency improvement will result in a reduction of up to 277,000
metric tons of carbon dioxide (CO2) emissions annually, according
to APB. The 11-foot high winglets could also extend the range of an
aircraft by as much as 360 nautical miles and improve take-off
performance, providing as much as 12,000 pounds of additional
The winglet installation work was accomplished by American's
Maintenance & Engineering organization at its maintenance base
in Kansas City, MO. American expects to modify all of its 767-300ER
aircraft by 2011.
American has already completed Blended Winglet installation on
its fleets of 124 Boeing 757s and 77 Boeing 737s.
