FSX Bombardier Learjet 60. The Learjet 60 is an improved version of the Learjet 55, with a longer fuselage and more powerful engines. It first flew in June 1991 and received FAA certification in January 1993. The modifications that converted the Learjet Model 55 into a Model 60 resulted from an aerodynamics improvement program and a need to increase the capacity of the Learjet product line. Several of these modifications were a first for Learjet. They include an all new inboard wing cuff added to the inboard sections of the "Longhorn" wing and an all new wing-to-body fairing. By increasing the wing chord and the leading edge droop, the wing cuff improved handling during approach and landing while the wing-to-body fairing reduced the interference drag between the wing and the fuselage. Since the engines were new for this aircraft, a new engine pylon had to be designed.
