==== Wingtip fence ====
A wingtip fence refers to the winglets including surfaces extending both above and below the wingtip, as described in Whitcomb's early research.<ref name="NASA innovation" /> Both surfaces are shorter than or equivalent to a winglet possessing similar aerodynamic benefits. The [[Airbus A310-300]] was the first airliner with wingtip fences in 1985.<ref>{{cite web |url= http://www.airbus.com/en/corporate/innovation/ |work= Corporate information – Innovation & technology |publisher= Airbus |title= From the A300 to the A380: Pioneering leadership |url-status= bot: unknown |archive-url= https://web.archive.org/web/20090421092103/http://www.airbus.com/en/corporate/innovation/ |archive-date= 2009-04-21 }}</ref> Other Airbus models followed with the [[Airbus A300-600|A300-600]], the [[A320ceo]], and the [[Airbus A380|A380]]. Other Airbus models including the [[Airbus A320 Enhanced]], [[A320neo]], [[Airbus A350|A350]] and [[A330neo]] have blended winglets rather than wingtip fences. The [[Antonov An-158]] uses wingtip fences.
