==== Canted winglets ====
[[Boeing]] announced a new version of the [[Boeing 747|747]], the [[747-400]], in 1985, with an extended range and capacity, using a combination of winglets and increased span to carry the additional load. The winglets increased the 747-400's range by 3.5% over the 747-300, which is otherwise aerodynamically identical but has no winglets. The 747-400D variant lacks the wingtip extensions and winglets included on other 747-400s since winglets would provide minimal benefits on short-haul routes while adding extra weight and cost, although the -400D may be converted to the long-range version if needed.<ref name="bca_aero_17_wingtip_devices"/> Winglets are preferred for Boeing derivative designs based on existing platforms, because they allow maximum re-use of existing components. Newer designs are favoring increased span, other wingtip devices or a combination of both, whenever possible.{{citation needed|date=November 2017}}

The [[Ilyushin Il-96]] was the first Russian and modern jet to feature winglets in 1988. The [[Bombardier CRJ-100]]/200 was the first regional airliner to feature winglets in 1992. The [[Airbus A340|A340]]/[[Airbus A330|A330]] followed with canted winglets in 1993/1994. The [[Tupolev Tu-204]] was the first [[narrowbody]] aircraft to feature winglets in 1994. The [[Airbus A220]] (née CSeries), from 2016, has canted winglets.
