Open systems streamline helicopter avionics upgrades - Military Embedded Systems
Military helicopter avionics upgrades like those for Future Vertical Lift platforms make data and modular-agnostic hardware a priority for defense electronics manufacturers. As systems and electronics evolve, many of these advances will have to comply with open architecture standards like the Future Airborne Capability Environment (FACE) and must leverage a modular open systems approach (MOSA) to ease cost and time-to-market pressure.
