Identify one of the main design features of the CRJ's wings.

The wings of the CRJ (Canadair Regional Jet) are specifically engineered to ensure optimal aerodynamic performance at varying speeds, which is crucial for regional jets that often operate in different phases of flight, such as takeoff, cruising, and landing. The design incorporates elements such as wing shape, aspect ratio, and airfoil contour, all of which contribute to reducing drag and improving lift. This aerodynamic efficiency not only enhances fuel efficiency but also allows the aircraft to perform reliably across a range of operational conditions, making it versatile for regional air travel.

While features related to fuel capacity, engine accommodation, and de-icing systems are also important, they do not fundamentally define the primary design purpose of the wings. The emphasis on aerodynamic performance reflects the aircraft's need to operate effectively in the performance envelopes expected of regional jets, thereby highlighting its design priority on speed and efficiency.
