Military aviation training faces many new challenges today with the introduction of networked or distributed mission training. One of the challenges that must be met is the need to improve the effectiveness and efficiency of instructors in what is becoming an increasingly complex and demanding training environment. Another challenge is the need for system acquisition cost saving methods in relation to major training subsystems. The present work is based upon previous research (Walwanis Nelson, Smith, Owens, Stubbs, & Bergondy-Wilhelm, 2003) and brings focus upon both of these issues in seeking new ways to improve the usability and capabilities of the Instructor Operator Station (IOS) subsystem, which is a key component of all modern aviation simulation systems (Farmer, Van Rooij, Riemersma, Jorna, & Moraal, 1999). Findings from interviews with instructional personnel across seven Navy aviation platforms concerning IOS requirements are reviewed and a framework for a Common IOS (C-IOS) is proposed in order to achieve improved training support and system acquisition cost savings objectives. Ways in which training personnel will benefit through improved strategies and capabilities to meet requirements such as scenario development, performance measurement, and mission debriefing are discussed. Further development of the concepts and infrastructure to implement the C-IOS across Navy aviation platforms is needed to demonstrate the proposed payoffs of these scientific and technological advances.
