Aviation Partners (API) of Seattle expects supplemental type certification of its blended winglets on the Raytheon Hawker 800A/B, dubbed the 800SP, in January. A number of "false starts" delayed the process by around two months, API says. Around 260 Hawker 800A/Bs are candidates. Winglets cut fuel consumption by 7%, increasing range by 335km (180nm). The Hawker 800SP also has a 2,000ft (600m) higher initial cruise altitude than a standard 800A/B, and can cruise at Mach 0.75-0.76 with the same fuel consumption as the standard aircraft at M0.73. API is also working on winglets for 340 later-version 800XPs.
