What type of wings improve aerodynamic efficiency?

Narrow and long wings are designed to reduce induced drag, which is a significant factor affecting aerodynamic efficiency, especially at lower speeds and during climb. This design allows for better lift-to-drag ratio when flying. The long aspect ratio means that the wings have a greater span relative to their chord (the width of the wing), which helps to smooth out the airflow over the wings and minimizes turbulent flow. As a result, aircraft with long, narrow wings can fly more efficiently, as they create less drag while producing the same lift compared to wider wing designs.

Narrow and long wings are often found on gliders and high-performance aircraft designed for optimal fuel efficiency and performance at altitude. This contrast in wing design highlights why long, narrow wings are favored for maximizing aerodynamic efficiency in such applications.
