Flight testing was nearing completion in late 2008, with FAA [[supplemental type certificate|supplemental type certification]] expected in 2009. The winglets increase range by 150 nm, lower fuel burn by 4β5%, improve hot and high performance as well as climb rate, permitting a climb to [[flight level]] 430 in 22 minutes, as opposed to 26 minutes without the modification. Climb to flight level 450 at maximum takeoff weight is possible without a [[step climb]].<ref>{{cite news|title=Winglet Technology Nearing Completion of Cessna Citation X Elliptical Winglet Flight Testing |url=http://www.skycontrol.net/industry/winglet-technology-nearing-completion-of-cessna-citation-x-elliptical-winglet-flight-testing/ |url-status=dead |access-date=22 June 2009 |publisher=Sky Control |date=5 October 2008 |archive-url=https://web.archive.org/web/20081009045721/http://www.skycontrol.net/industry/winglet-technology-nearing-completion-of-cessna-citation-x-elliptical-winglet-flight-testing/ |archive-date=2008-10-09 |location=Orlando, FL }}</ref> Cruise speed at altitude is expected to increase by 15 knots, and maximum takeoff weight will increase by 1200 lbs (545 kg).
