Single fault impervious integrated control and monitoring system

A single-fault-impervious integrated control and monitoring avionic system, comprising:

• a. a pair of concentrators interchangeably capable of assuming primary and secondary status, respectively;
• b. a plurality of workstations, one of said workstations being a Remote Master Workstation;
• and
• c. a pair of independent communication paths each interconnecting one of said pair of concentrators with said workstations;
• d. each of said pair of concentrators being connected in parallel to a plurality of avionic equipment interfaces arranged to convey avionic equipment data to said concentrators and to convey operational commands from said concentrator to said avionic equipment;
• e. said pair of concentrators being so interconnected with each other that whenever one of them is in primary status, the outputs of the other are blocked but its inputs continue to function, each of said concentrators providing a status signal that is transmitted directly between said concentrators.
