These features make the proposed control architecture very appealing for reconfiguration purposes. 5. Numerical validation The FCS has been applied in a case study with a large transport aircraft. The works has been performed within the GARTEUR Action Group 16 project focused on Fault-Tolerant Control. In that project a benchmark environment Smaili et al. 2006 has been developed modelling a bunch of surface actuators faulty conditions. A brief summary of all these conditions is given in Table 3 while a detailed explanation of the benchmark can be found in Smaili et al. 2006 . Several manoeuvres are considered in the benchmark to be accomplished in the various faulty conditions. The test results are here shown both in terms of time histories of the state variables and with a visual representation of the trajectories performed by the airplane. Stuck Ailerons Both inboard and outboard ailerons are stuck. Stuck Elevators Both inboard and outboard elevators are stuck. Stabilizer Runaway The stabilizer goes at the maximum speed toward the maximum deflection. Rudder Runaway The upper and lower rudders go at the maximum speed toward the maximum deflection. Loss of Vertical Tail The vertical tail separates from the aircraft. Table 3. Failures considered in the test campaign Only the most meaningful conditions are here reported and discussed. To better demonstrate the improvement of fault-tolerance achieved by adopting the adaptive control in conjunction with the Control Allocation comparison is made between three versions of the FCS the first is a baseline SCAS developed with classic control techniques. The two remaining FCS are based on the adaptive SCAS with and without the CA respectively. As above said only limited FD information are supposed to be provided that is the information about whether an actuator is failed or not but the current position of the failed .
