Auxiliary Maintenance Computer (AMC)

The Auxiliary Maintenance Computer (AMC), developed by Demo Systems for the C-5 aircraft, is a ruggedized high performance airborne server supporting Mil-Std-1553B avionic busses and an Ethernet network.

• The AMC is designed for harsh environments and features solid-state flash drives to ensure high reliability and enhanced functionality at higher altitudes. It runs with a Windows 2000 Server operating system on an Intel 1.2 GHz PIII processor. The AMC supports six (6) dual redundant 1553B serial interfaces, and ten channels of switched 10 BaseT/100 BaseTX Ethernet.
• The AMC is based on Demo Systems’ Network Server Units (NSU), which is designed for commercial aircraft in accordance with ARINC Characteristic 763 (Network Server System). The NSU and AMC meet ARINC 600 6-MCU size, power and cooling requirements for airborne equipment. Three generations of NSUs have been developed and flight certified in partnership with Honeywell for Global Express and Citation aircraft.
• Network servers support the following functions: collect flight data and fault information, link to high-speed air-ground data link to provide e-mail and web server access, provide graphical weather reports, navigation charts, store loadable OFP software for all airborne systems, and perform dataloading via MIL-STD 1553 and ARINC 615/615A.
