What is the main advantage of straight wings?

The main advantage of straight wings lies in their ability to provide efficient lift at low speeds. This characteristic makes them particularly beneficial for aircraft that need to operate effectively during takeoff and landing phases, where low-speed performance is crucial. Straight wings generate adequate lift without requiring high speeds, allowing for shorter takeoff and landing distances, which is important for certain types of aircraft, especially those used in general aviation and smaller regional transport.

While other wing designs might excel at high speeds or supersonic travel, straight wings hold an advantage for low-speed operations by facilitating stable flight characteristics and easy handling. Additionally, they contribute to improved performance and safety during low-speed maneuvers, which is essential for training and utility aircraft that often operate in various environmental conditions.
