Abstract
The MV-22A training device suite Operational Flight Trainer (OFT) and Aircrew System Trainer (AST) specification requirements provide for an instructor work environment that focuses on integrating the instructor's position with the training environment. This paper will describe the process to refine a display/switch design dedicated to over-the-shoulder instruction at the IOS. The time frame encompasses the period from the mockup through the IOS-specific design reviews which addresses a mature IOS display/switch design. This new IOS display/switch design mirrors the aircraft's Multi-Function Displays (MFDs) which provide the pilots rapid and efficient access to aircraft systems and environmental data, while allowing for primary focus on flying the aircraft. Correspondingly, the IOS display/switch design for control and monitor of the training scenario, allows the instructor to focus on trainee actions, the aircraft instrument panel, and the visual system's forward field of view. Since the mockup, there has been a refinement process leading to some significant design initiatives. An analysis of this refinement process points out some key issues in designing for this new type of IOS display.
