This function adjusts the rudder left and right rudder
angle of winglet speci¿cations fuselages.
Winglets are used to improve the efficiency of
aircraft lowering the lift-induced drag caused by
wingtip vortices. The winglet is a vertical or angled
extension at the tips of each wing.
Winglets work by increasing the effective aspect
ratio wing without adding greatly to the structural
stress and hence necessary weight of its structure - an
extension of wing span would also permit lowering
of induced drag, though it would cause parasitic drag
and would require boosting the strength of the wing
and hence its weight - there would come a point at
which no overall useful saving would be made. A
winglet helps to solve this by effectively increasing
the aspect ratio without adding to the span of the
wing.
