The wing of the Learjet Model 60 was tailored for improved aerodynamic characteristics using the TRANAIR transonic full-potential CFD code. A root leading edge glove and wing tip fairing were shaped to reduce shock strength, improve cruise drag and extend the buffet limit. The aerodynamic design was validated by wind tunnel test and flight test data.

The stall characteristics of Learjet aircraft are discussed in terms of the aerodynamic phenomena which determine the stall behavior. A number of devices are described which have been flight tested in attempting to improve controllability at stall. Theories are offered to explain the effects of each device. Wind tunnel test data are compared with some of the flight results.
