What innovation did the Wright Brothers implement that was key to their aircraft's flight control?

The Wright Brothers' implementation of wing-warping was crucial for achieving controlled flight in their aircraft. This innovative technique allowed the pilot to alter the shape of the wings by twisting them in response to the aircraft’s motion through the air. This adjustability was vital for maintaining lateral control, which is the ability to manage the roll of the aircraft.

Before the Wright Brothers, most designs lacked effective methods for controlling an airplane in three dimensions, especially during turns. Wing-warping provided a solution to this problem by enabling the aircraft to bank left or right without the need for ailerons—structures that were introduced in later aircraft designs. This method functioned effectively alongside the Wright Brothers’ other innovations, such as the canard (the upfront horizontal stabilizer), to help stabilize the plane during flight.

This fundamental aspect of their design not only marked a turning point in aviation history but also laid the groundwork for future developments in flight control. The success of their powered flight was significantly attributed to their unique approach to controlling wing deformation, which enhanced their ability to maneuver and maintain flight stability.
