Which wing shape is described as long and narrow for optimal flight?

• A. Long and narrow
• B. Short and broad
• C. Delta-shaped
• D. Wide and rounded

Answer: (A)

High aspect ratio wings are best for efficient, steady flight. A wing that is long and narrow has a large wingspan relative to its chord, which lowers induced drag by spreading lift more evenly and reducing tip vortices. This improves the lift-to-drag ratio, giving a better glide ratio and saving energy during cruise. That’s why gliders and birds that travel long distances typically use long, slender wings. Other shapes—short and broad, delta-shaped, or wide and rounded—change how drag and lift behave at different speeds and attitudes, often trading efficiency for maneuverability, stability, or high-speed performance. So the long and narrow wing is described as optimal for flight in terms of efficiency.
