The use of ICNIA will significantly improve the avionics suites of military aircraft. Advantages of ICNIA include Reduction in space, weight, power and cooling requirements Increase in reliability and maintainability Decrease in life cycle cost Ease of integration into an avionics suite via a multiplex bus and Reconfigurability. To take advantage of these features, certain design guidelines should be followed. The basic guideline is that the airframer should control the integration of any subsystem into his avionics suite. This implies that the ICNIA interface software, and possibly some of the hardware, must be in accordance with the integration philosophies of the host platform. These philosophies will vary from one accordance with the integration philosophies of the host platform to the other. General Dynamics has an integration and partitioning concept which has functioned exceptionally well on the F-16. Each subsystem should perform its entire task and the interfaces between subsystems should be as simple as possible. This concept has three major advantages Changes to one subsystem are transparent to other subsystems and do not result in changes being required in other subsystems when one subsystem is changed The integration of a new subsystem into the avionics suite is not difficult since a new system does not require unique support of other subsystems and Fault isolation is simple since each subsystem performs an entire task.
