Abstract:

This report informally specifies the general functions, data interactions, and timing constraints for a hypothetical avionics mission control computer MCC system typical of those found in some existing U.S. Navy and Marine Corps aircraft. Avionics functions and equipment are described only to the extent needed to specify generic MCC behavior. The specification was developed primarily to exemplify timing requirements and functional interactions in a heavily loaded real time system. The devices, functions, and architecture presented here were prepared for illustrative purposes and are not those of any specific military aircraft. In particular, the quantitative timing information and discussion of functional interactions is hypothetical. The specification consists of an introductory description of the environment in which the mission computer operates followed by a functional description of the requirements imposed on the mission computer. The functional description is minimal and serves mainly to characterize computer workload and data interactions. An appendix contains a summary of the timing requirements together with an analysis of the expected CPU load for a possible attack scenario.
