Winglets

Quiet Wing Corporation developed, certified and installed the first winglets on commercial category aircraft in 1993. Since then, the technology developed by Quiet Wing has been well recognized as a significant contributor to fuel savings, reduction in CO2 emissions, noise reduction and overall aerodynamic improvements.

The winglets provide a reduction of drag inducing wingtip vortices. This enables the aircraft to achieve:

• Payload increases
• Lower thrust levels required throughout the flight envelope leading to lower engine maintenance costs
• Noise reduction
• Fuel savings, depending on the stage lengths of up to 6%
• Extended range
• Substantial Emission Reductions

The Winglet System consists of the winglets and a patented modification to the flap system. It is certified on all models and variants of the B727 series aircraft and hundreds are still in service worldwide.
