What is a characteristic of a wing with a very high aspect ratio?

• A. It has a high stall speed
• B. It has a low stall speed
• C. It generates more drag
• D. It requires more power to maintain altitude

Answer: (B)

A wing with a very high aspect ratio features a long span relative to its chord length, which significantly impacts its aerodynamic properties. One of the primary characteristics of such wings is their ability to achieve lower stall speeds. This is mainly due to the increased lift-to-drag ratio that high aspect ratio wings typically possess, allowing them to generate sufficient lift at lower speeds. The aerodynamic design promotes a smoother airflow over the wing, which enhances lift production and delays flow separation. As a result, aircraft equipped with high aspect ratio wings can be flown at lower speeds without stalling, making them efficient for gliding and slow flight conditions. This characteristic is particularly beneficial for specific types of aircraft, such as gliders and some types of sailplanes, where lowering stall speed is advantageous for maximizing performance during flight.
