In 2000 an I/ITSEC paper (George et. al. (2000)) was published that provided a description of the systems, subsystem components and functionality of the Aviation Combined Arms Tactical Trainer - Aviation Reconfigurable Manned Simulator (AVCATT-A). The intent of this paper is to expound on the numerous technical innovations that are being incorporated in AVCATT-A to facilitate improved training and a higher level of warfighter readiness. A primary objective is to explain to users how the innovations provide training advances over previously available technologies (in terms of training effectiveness and/or cost effectiveness). The paper will discuss the advances in reconfigurability that have been achieved using new products and innovative designs. Innovations in exercise initialization and control will also be discussed including a cost effective methodology for transferring avionics initialization data from real-world Aviation Mission Planning Systems (AMPS). Innovations will be discussed that relate to advances in the synthetic environment being provided to support the aviator's combined arms training, including modifications to facilitate and enhance the first use of OneSAF Test Bed Semi Automated Forces (OTBSAF) in a major training system. Advances in virtual-to-virtual and virtual-to-live interoperability technologies will be described including the development of correlated databases from Synthetic Environment Data Representation and Interchange Specification (SEDRIS) source data and a Federation Object Model (FOM) Agile Distributed Interactive Simulation/High Level Architecture (DIS/HLA) gateway. The paper will also describe the use of state-of-the-art products for distributed processing, networking, displays and digital sensor video recording, monitoring and playback.
