Increases Maximum Zero Fuel Weight And Upgrades Take-Off And Landing Data
The FAA has granted an STC To Wichita, Kansas-based Winglet Technology for Take-Off and Landing Data (TOLD) and Maximum Zero Fuel Weight (MZFW) increase upgrades for winglet equipped Citation X. Winglet Technology is offering the FMS TOLD and 150 lb MZFW increase service bulletin upgrades to Citation X winglet customers. The FMS TOLD upgrade requires an upgrade of the Integrated Avionics Computer (IAC) which includes the long awaited NZ6.1 FMS upgrade.
The TOLD service bulletin installs the winglet STC AFM take-off and landing v-speed database and upgraded IAC required to accept the STC AFM TOLD. The MZFW service bulletin increases the MZFW from 24,400 lb to 24,550 lb to offset the 135 lb empty weight increase of the winglet STC installation.
Winglet Technology was granted an FAA Supplemental Type Certificate (STC) to install their elliptical winglet design for Cessna’s Citation X, the world’s fastest business jet, in July of 2009. Cessna Aircraft Company has made Winglet Technology’s winglet design standard for its larger, faster upgraded version of the Citation X beginning with delivery of aircraft S/N 501.
Winglet Technology’s elliptical winglet design provides superior aerodynamic performance across a broad range of Mach number and operating conditions. The elliptical design ensures the lift distribution of the wing closely matches optimum lift distribution along the span of the wing, which minimizes the induced drag of the aircraft. The resulting induced drag reduction enhances the overall operational performance and translates into a range of performance improvements for the both the Cessna Citation X and Sovereign aircraft.
