Abstract:

The study was conducted to lay the initial groundwork for a smooth and timely interface between the AIMIS Advanced Integrated Modular Instrumentation System and the AAES Advanced Aircraft Electrical System. Primary failure modes of the SOSTEL Solid State Electric Logic system are identified. Level of criticality is indicated for each failure mode and priorities for display of malfunction information are established. Multimode switch approaches and interface memory requirements are discussed. Techniques are established for converting failure data into messages the pilot can immediately understand. A word code technique is recommended as a means for simplifying the SOSTELAIMIS interface and minimizing interface memory requirements. The A-7B power distribution and armament station control unit ASCU subsystems are used as the data base for the study.
