This chapter deals with the next step following the design of an FDD system, i.e. appropriate recovery strategies, based on all available actuator/sensor/communication resources. An active fault tolerant flight control strategy based on H∞ design tools is presented. The Fault Tolerant Control (FTC) strategy operates in such a way that once a fault is detected and confirmed by an FDD unit, a compensation loop is activated for safe recovery. A key feature of the proposed strategy is that the added FTC loop keeps unchanged the in-service control laws facilitating the certification of the whole approach and limiting the underlying Verification and Validation activities. The methodology is applied to actuator fault accommodation of a large commercial aircraft during landing approach. The results, obtained from a piloted 6-DoF flight simulator, will be presented and discussed. The application is taken from the GARTEUR project. The problem studied in this chapter is that of design and analysis of an active flight fault-tolerant control system. The chapter presents a practical case study taken from the European GARTEUR project (Flight Mechanics Action Group 16) on fault-tolerant control. Piloted flight simulator experiments are presented which show that fault tolerance can be achieved provided that there exists sufficient onboard control authority.
