Modern aircraft do not use wing warping primarily because ailerons have proven to be a more effective and efficient control mechanism for banking and rolling.
Here are a few reasons why wing warping has been largely replaced by ailerons:
1. Control Effectiveness: Ailerons provide more precise and predictable control over an aircraft's banking and rolling compared to wing warping. Ailerons are independent control surfaces located on the trailing edge of the wings, allowing each wing to move independently. This enables differential control, where one aileron can be deflected upwards while the other is deflected downwards, resulting in aileron-induced differential lift that facilitates the desired banking motion. This differential lift enables better control authority and stability during turns.
2. Structural Considerations: Wing warping required a flexible wing structure that could be deformed to generate differential lift. This design was complex and demanded intricate mechanical linkages running through the wing, which added weight and complexity to the aircraft's structure. Ailerons, on the other hand, are relatively simple and can be added as separate movable surfaces without affecting the overall wing structure and integrity.
3. Control Balance: Wing warping often resulted in a coupling effect in which roll control influenced yaw and vice versa. This linkage between roll and yaw could complicate control and lead to potentially unstable flight conditions. Ailerons, being independent control surfaces, allow for separate control of roll and yaw, maintaining better control balance and avoiding unwanted interactions between different flight control axes.
4. Safety and Redundancy: Ailerons can be designed with redundancy, enabling multiple control surfaces on each wing. This redundancy enhances safety and provides the pilot with more options in the event of an aileron malfunction or failure. Wing warping did not offer such redundancy.
5. Pilot Technique and Training: Ailerons are generally easier for pilots to operate and require less training compared to wing warping. The simplicity and intuitive nature of aileron controls make it more accessible for pilots, ensuring safer and more efficient aircraft operations.
While early aircraft successfully utilized wing warping for basic turns and control, advancements in aeronautics and the development of more efficient control surfaces like ailerons led to the abandonment of wing warping in favor of safer and more effective control mechanisms for modern aircraft.

Early wing structures were rather flexible and relatively easy to warp. Modern aluminium wings with wing boxes incorporated are very rigid (as they have to deal with high loads) and therefore ailerons are used for banking.
You are correct in noting the difference in wing structure between early aircraft and modern ones. Early aircraft had flexible wing structures that could be warped, whereas modern aircraft wings are designed to be rigid to withstand the high loads experienced during flight.
Modern aircraft wings are typically made of strong and lightweight materials like aluminum, composite materials, or a combination of both. These materials provide structural rigidity and strength necessary to handle the aerodynamic forces and loads encountered during flight. The wing structure of a modern aircraft often includes a wing box—a rigid structure that provides support and distributes loads across the wing.
With these rigid wing structures, wing warping is not practical or feasible as it would require significant changes to the fundamental design and construction of the wings. Utilizing wing warping on a rigid wing would introduce structural issues and potentially compromise the integrity and performance of the wing.
In contrast, ailerons are movable control surfaces attached to the trailing edge of the wing. They are structurally separate from the main wing structure and can be operated independently. Ailerons, being separate control surfaces rather than integral parts of the wing, allow for efficient control of banking and rolling motions without compromising the structural integrity of the wing.
So, while the development of modern, rigid wing structures necessitates the use of ailerons for banking, it is important to acknowledge that these advancements in wing design and materials made aileron-based control systems the more efficient and practical choice for modern aircraft.
