Microcomputer control applications in integrated flight/weapon control system

This paper discusses the integrated flight/weapon control system (IFWCS) of a fighter aircraft. The IFWCS enhances flight performance and accurate weapon delivery through an onboard microcomputer control system. With the IFWCS the pilot is able to perform the flight and attack roles with the aid of multi-function cockpit displays of numerous flight and tracking commands. The IFWCS reduces pilot workload and increases weapon delivery capabilities and aircraft survivability. In the IFWCS, the mission computer serves as the center of interaction between the flight control system and the weapon control system. It prescribes optimal trajectories to be followed automatically by the flight control computer. The trajectories include preparation path, intercept path, attack path, and escape path. The pilot acts as the flight/weapon mission manager. In designing the IFWCS, attention must be given to the limited cockpit space. Therefore, the use of microprocessors is essential in the building of the IFWCS. A pipelined multimicroprocessor computer system will enable the onboard computer to function much faster than real-time, thus increasing the effectiveness of the IFWCS. This microcomputer control application in the IFWCS will contribute to significant mission improvement. The specifications and review of the IFWCS software/hardware are also discussed including the implementation of the MIL-STD-1750A chip set. Also to be considered in the design of the IFWCS is the pilot´s physiological capability.
