These winglets will improve the performance of your aircraft in every phase of flight. Advantages offered by the winglets include:
Shorter takeoff runs
Improved aileron response
A better rate of climb
Faster cruise speeds
Improved single engine performance
Increased in flight stability
Shorter landing rolls
Added resale value
The basic purpose of winglets is to reduce lift-induced drag by breaking up wingtip vortices. But that primary function sets off a chain reaction of other favorable characteristics including those listed above. The winglets reduce yaw --- especially yaw in turbulence. During stalls, they prevent the wingtip from stalling first, thus reducing the tendency of one wing dropping before the other.
