My previous post on this subject, which Boeing727, appears to have overlooked, stated that the first SAA 737-800s would be arriving without the high-tech carbon-graphite winglets, as these would only become available towards the end of this year. All the SAA '800s delivered between now and the end of the year will have the winglets retro-fitted at a cost of $800 000 per pair.

Thanks for the clarification, my mistake on missing your earlier post.

What kind of range will winglets give the 737-800? And what will the retrofit entail? $800,000 seems a bit steep for a pair of winglets.

A Next-Generation 737-800 equipped with the new winglet will be able to fly farther, burn 3 percent to 5 percent less fuel, or carry up to 6,000 pounds more payload. Other benefits include a reduction in noise near airports, lower engine-maintenance costs, and improved takeoff performance at high-altitude airports and in hot climate conditions.

The winglets weigh about 120 pounds each. They are made of high-tech carbon graphite, an advanced aluminum alloy and titanium. The winglet is eight feet long and tapers from its four-foot wide base to a width of two feet at the tip. Unlike traditional winglets typically fitted at abrupt angles to the wing, this new advanced "blended" design gently curves out and up from the wing tip, reducing aerodynamic drag and boosting performance.

The 737-800 winglet was developed initially for the Boeing Business Jet (BBJ), which also features the state-of-the-art 737-800 wing. This winglet will be available initially as an option on the 162-passenger 737-800. Formal availability of the winglet will follow quickly on other models that feature the 737-800 wing, including the 737-700C and the 737-900. The applicability of the winglet to Next-Generation 737-600 and 737-700 models is being assessed.

The blended-winglet technology was developed by Aviation Partners Inc. of Seattle. In 1999, during the design of the BBJ winglet, Aviation Partners and The Boeing Company formed Aviation Partners Boeing (APB), a joint venture that completed and owns the design. APB is developing the capability to make the winglet available as a retrofit for airplanes already in service.

SAA will not be the first airline to receive B737-800s equipped with winglets, even though they were the first to order them. The first in-service B738 with winglets will be one of Hapag-Lloyd's new orders for delivery early next year. This aircraft will also serve as the testbed for the certification process. Hapag-Lloyd was the third airline to order the winglets, after SAA and ATA.

All SAA's B738s are receiving the wing mod's required for the winglets in the meantime, so that when certification is obtained for the winglets later this year they can simply be bolted on.

American has also expressed an interest in the winglets, but their already-delivered aircraft will require the wing mod's before the winglets can be fitted.
