LONDON. Many questions on open architecture initiatives and the Department of Defense (DoD) modular open systems approach (MOSA) mandate were being floated to U.S. embedded hardware and software suppliers at DSEI in London this week. So, over dinner last night, I asked Chip Downing, Outreach Committee Co-chair of the Future Airborne Capability Environment (FACE) Consortium and Senior Market Development Director for Aerospace and defense at RTI, what type of open architecture strategies are being pursued by European defense departments and if the U.S initiatives like FACE influenced those efforts.
