Question

Winglets are used to reduce

• A. Pressure drag
• B. Wave drag
• C. Induced drag
• D. Trim drag

Hint:

Winglets improve the lift-to-drag ratio of aircraft wings and can significantly enhance fuel efficiency by reducing vortex strength at the wingtips.

Answer 1

The Correct Option is C

Winglets, the small vertical projections at the wingtips, are primarily designed to reduce induced drag, which is generated by the wingtip vortices that form as a result of high-pressure air from below the wing rushing over the wingtip to the lower pressure air above.
