a) Increase thrust
b) Reduce turbulence at the tips of an airplane’s wings
c) Decrease thrust
d) Increase turbulence at the tips of an airplane’s wings
Answer: b
Explanation: The purpose of winglets is to reduce turbulence at the tips of an airplane’s wings. Winglets and sharklets are similar to each other. The wingtip vortices created by a large aircraft are strong enough to flip a smaller aircraft that maybe flying closely. Winglets are responsible to break these vortices thereby reducing drag on the airplane
