It Will Be One With Winglets Then

Some of the Boeing 757-200 fleet, particularly those being used on further afield destination such as Egypt, Greek Islands and Cyprus, are being retro-fitted with blended winglets. These are vertical extensions to the wings (photo along the 737-800 wing here showing the winglet). Without getting too technical, these winglets are being fitted to many aircraft types as they increase lift and reduce drag by reducing air 'escaping' from the edge of the wingtip. The 'escaping' air causes wintip vorticies and drag. In effect, the last section of the wing produces little lift and is inefficient. The addition of winglets significantly reduces this allowing the wing to perform more efficiently producing aerodynamic benefits to the airframe including;
A reduction in fuel burn and emmissions (less power to produce the same lift)
A reduction in engine maintenance (as they are less stressed)
Improved range and/or payload
Improved handling and stability
Faster climb to altitude
Increased initial cruise speed
Greater safety margins
Environmental benefits
Thomson Airways are due to receive blended winglets on their 767-300/ER fleet later this year with initial figures suggesting a 6.5% reduction in fuel burn.
