What is the consequence of a chord that is too long on a wing designed for high performance?

• A. Increased fuel efficiency
• B. Increased drag during flight
• C. Improved maneuverability
• D. Reduced stall speed

Answer: (B)

A wing designed for high performance must balance multiple aerodynamic factors to achieve optimal flight conditions. When the chord of a wing is too long, it increases the surface area exposed to the airflow, which in turn elevates the pressure drag on the wing. This additional drag occurs because a longer chord means that there is more air resistance acting against the forward movement of the aircraft, particularly at higher speeds. Increased drag directly impacts the aircraft's performance by requiring more power to maintain speed, which can lead to increased fuel consumption and diminished overall efficiency. For high-performance aircraft where every bit of drag counts, this can significantly hinder the design objectives that aim for speed and agility. Hence, a longer chord, while it might influence lift and other flight characteristics, primarily tends to increase drag during flight, making it an undesirable trait for wings that are optimized for high performance.
