This paper will provide insight on how low-cost PC-based simulators can provide meaningful training to the war fighter given current advancements in the video gaming industry. It will also describe a new opportunity to add a Department of Defense (DoD) compatible interoperability interface to PC Aviation Training Devices (PCATD) based on Microsoft's Direct Play technology used by many commercial-off-the-shelf (COTS) flight simulators. This paper will attempt to provide a vision of how the PCATD will fit into the Navy's future training capabilities, given the new possibilities for interoperability in a distributed military simulation environment. The initial results of NAVAIR Orlando's interoperability concept study will be presented.
