Does the Boeing 767 have winglets?
FAA and EASA certification of 767-300ER Blended Winglets is anticipated for November of this year with entry into revenue service following in December. “The 767-300ER Blended Winglet program launch has been our most successful to date,” says Aviation Partners Boeing’s President and CEO, John Reimers.
Why do some 767 have winglets?
An airline that installs winglets on its fleet of 58 Boeing 767 jets is expected to save 500,000 gallons of fuel annually. Winglets help mitigate the effects of “induced drag.” When an aircraft is in flight, the air pressure on top of the wing is lower than the air pressure under the wing.
When did the 767 get winglets?
During the same period, operators upgraded aircraft already in service; in 2008, the first 767-300ER retrofitted with blended winglets from Aviation Partners Incorporated debuted with American Airlines.
How much does a winglet weigh?
about 132 pounds
(All Next-Generation 737 models have the same wingspan.) Each winglet weighs about 132 pounds. Increased weight to the airplane for modifying wing and installing winglets is about 480 pounds….Benefits.
| Series | Range (nm) Normal | Range (nm) With Winglets |
|---|---|---|
| -700 | 3250 | 3634 |
| -800 | 2930 | 3060 |
| -900 | 2670 | 2725 |
Do all airplanes have winglets?
Several airliners use them. The Airbus A319 and A320 have very small upper and lower winglets. The longer-range twin-engine A330 and four-engine A340 have conventional winglets, as do Boeing 747-400s.
Why do only some planes have winglets?
Aircraft manufacturers have been using additional ‘bits’ on the ends of wings since the beginning of the 2000s. These small additions, commonly known as winglets, are designed to improve the efficiency of the aircraft by reducing drag.
What is a Boeing winglet?
Winglets are added to the end of a plane’s wings to reduce drag and ultimately enable more efficient flight. They work by reducing a process known as vortex drag, caused by different air pressures converging at the tips of each wing and slowing the aircraft down.
