Winglet Technology, LLC and Cessna Aircraft Company have collaborated to develop the world’s fastest winglet for the world’s fastest civilian aircraft with a top speed of .92 Mach. Winglet Technology worked closely with Cessna Aircraft Company to develop a Supplemental Type Certificate (STC) permitting the installation of the Elliptical winglets on the Cessna Citation X business jet.
The STC includes updated Airplane Flight Manual and Operations Manual Supplements, updated version of CESSNAV including CPCalc, Ops Manual, and CLCalc for customers who have previously purchased the CESSNAV subscription. The STC has been approved for pre-172 (with and without 400 lb gross weight increase) and post-173 serial numbers.
Winglet Technology received FAA approval of the Citation X winglet STC in June 2009. Since that time, the Citation X winglet STC has been approved by EASA (Europe), TCCA (Canada), ANAC (Brazil), and DGAC (Mexico).
The Elliptical winglet design provides significant performance improvements for the Citation X, including increased speed at higher altitudes, improved take-off performance, reduced time-to-climb, increased range and payload, improved cross wind capability, and improved directional stability.
- Increased speed at higher altitudes
- Improved hot day / high altitude take-off performance
- Increased range capability
- Higher initial flight levels
- Reduced time-to-climb
- Improved climb gradient
- Reduced fuel consumption
Up to 8% for high speed cruise flight profiles
- Reduced direct operating costs
Increased range reduces en-route technical stops
Up to 2,100 lb fuel savings per technical stop avoided
- Enhanced aircraft resale value
100% Blue Book value of installed winglet STC
The STC Installation includes the addition of the winglets, structural reinforcement to the outboard wing, navigation/anti-collision light in the tail, and upgrade of the IC-800 integrated avionics computer.
The winglet construction is a core stiffened carbon/epoxy laminate design which is resistant to damage. The integrated composite design eliminates external fasteners, giving it a smooth and sleek appearance. The leading edge skins are polished aluminum, and are attached with removable screws, allowing replacement in the event of damage. The attachment to the wing is an interchangeable joint which allows for convenient winglet replacement. The winglet and tail exterior lighting system utilizes all LED lights for significantly improved reliability.
