Many innovative solutions have been developed by the aeronautical sector toward achieving the future "sustainable" aircraft that will be cleaner, quieter, smarter, and more affordable. Weight reduction is one of the most significant contributors to sustainability, as it improves aircraft performance (fuel consumption, noise, range) and consequently decreases its environmental footprint. This article deals with two challenging electrical flight control system (EFCS) failure cases, which may affect structural loading. A simple model-based approach is presented for the robust and rapid detection of such failures. The techniques were tested and validated at the Airbus test facility, and real flight tests have confirmed that a high level of performance and robustness can be obtained.
