Winglet Technology (Booth 4359) has completed testing its new elliptical winglets on the Cessna Citation Sovereign. The Wichita firm is collaborating with the Citation service center network on the project and released test results for the $395,000 kit (excluding labor) here at NBAA.

Speed increases by 12 to 14 knots at FL450, time-to-climb direct to FL450 drops to 26 minutes and range increases 205 nm with payloads under 1,200 pounds and by 265 nm with payloads over 1,450 pounds.

The kit increases the wingspan from 63 feet 4 inches to 69 feet 4 inches and also is expected to enable a one-percent gross weight increase. Certification of the new winglets is pending and Winglet Technology expects entry into service in late 2015. The company certified its elliptical winglets for the Citation X in 2009 and Cessna has made them standard equipment on the new Citation X+.
