Which of the following is a benefit of the Boeing 787's wing design?

The design of the Boeing 787's wings is a key factor in enhancing the aircraft's overall performance, with the raked wingtips playing a significant role in improving fuel efficiency. This design allows for a more aerodynamic shape, which reduces drag, especially during cruise conditions. The raked wingtips extend the wing's effective span without increasing its overall length, optimizing lift-to-drag ratio. This aerodynamic efficiency translates directly into better fuel consumption, enabling airlines to benefit from lower operational costs while also contributing to reduced greenhouse gas emissions.

The increase in fuel efficiency is particularly critical in the aviation industry as it aligns with the growing emphasis on sustainability and cost-effectiveness. Wind tunnel testing and real-world performance data have shown that the wing design contributes to significant enhancements in the 787's range, making it suitable for long-haul flights without necessitating excessive fuel load.

Overall, the raked wingtips are a technological advancement that demonstrates how thoughtful aerospace engineering can result in more efficient aircraft, affirming the importance of wing design in modern aviation.
