Line 35: The final aerodynamic improvements to the Model 60 included the creation of the distinctive "[[Ogive]]" winglet trailing edge. This lengthening of the chord near the interface of the winglet and the wing improved the interaction of the wing’s pressure spike with the winglet’s pressure spike. The result was a significant lowering of the drag in this area and a significant improvement of the wing's efficiency. On the prior “Longhorn” wing the interference between the winglet and the wing nearly canceled the effects of the winglet. The single ventral [[fin]] was also replaced with two ventral fins that Learjet called "Delta Fins" to improve stall characteristics and promote aerodynamic stability. ~~The Learjet Model 45 winglet blend design took into account the lessons learned from the Model 60 and the [[ogive]] was not necessary.~~ Production of the Learjet 60 ended in 2007 after 314 aircraft had been built.
