When the United States Air Force (USAF) decided to update its C/KC-135s to GATM guidelines and the DO-178B standard, electronic displays and CDU (Control/Display Unit)-based flight management equipment were modified to be compatible with Rockwell Collins Integrated Processing Center (IPC) units. Most processing now occurs in the IPC, which provides multiple modular processing resources for hosting mission, flight-management, and display-management processing functions. DO-178 certification was achieved. |
The IPC is interfaced to an avionics-quality Ethernet Local Area Network (LAN). Inside the IPC cabinet is a series of Line Replaceable Modules (LRMs). Of these modules, the LynxOS-178 certifiable, safety-critical RTOS powers the IPC Common Computing Module (CCM) and the Input/Output Concentrator Module (IOC). Sources: |
