Winglet Technology of Wichita, Kan. (Booth No. C12043), the company that supplies its Elliptical Winglets for the Citation X, is collaborating with the Cessna service center network to offer the winglets for retrofit on the Citation Sovereign. Flight testing is expected to begin this month and the companies are targeting entry-into-service in the first quarter of 2015.
“The Elliptical Winglet upgrade will provide Sovereign owners and operators with even greater operational flexibility,” said Bob Kiser, Winglet Technology president and managing director. The winglets “are a great high-altitude complement to the Sovereign’s outstanding short-field performance.”
The company’s winglet modification will increase the Sovereign’s wingspan by five feet to 69 feet 4 inches. It will also add 350 pounds, increasing mtow to 30,650 pounds. (Winglet Technology expects the mtow increase to be approved as part of the STC.)
The upgrade will provide higher weight, altitude and temperature limits allowing for more flexibility during high/hot airport operations, better climb performance (allowing higher initial cruise altitudes), faster max cruise speeds at high altitudes and increased range for a given payload throughout the operating envelope. Winglet Technology has obtained U.S., European and Canadian approval for its Elliptical Winglet.
