Fault-tolerant flight control (FTFC) systems can prevent LOC-I and recover aircraft from its precursors. One group of promising methods for developing Fault-Tolerant Control (FTC) system is the Adaptive Critic Designs (ACD). Recently one ACD algorithm, called Value Function Based Single Network Adaptive Critic (J-SNAC), has emerged and it promises to make applications of ACD more practical by reducing the required amount of computations. This paper discusses the implementation of this framework for the design of a lateral-directional flight controller. The proposed flight controller is trained to perform coordinated-turns with an F16 simulation model. The trained controller was evaluated for tracking different heading command signals, robustness against sensor noise and partial failure of aerodynamic control surfaces. The controller is found to be effective for the considered assessments.
