The US Navy's PMA-205, in conjunction with the training and simulation industry, has benefited the Navy by developing and deploying the Operator Machine Interface Assistant (OMIA) part-task trainer for the MH-60S and MH-60R helicopters. This flexible, multi-platform, web-based crew trainer is currently in use by HSC-2, HSC-3, HSM-41, Navy helicopter maintenance organizations, and by fleet squadrons at port, home and when deployed at sea. Earlier versions have been in use for over nine years. OMIA benefits the warfighter by providing a simulation of the MH-60S/R Common Cockpit that includes a FLIR capability with optional hardware FLIR hand-control unit and acoustics simulations. This paper will describe the design decisions made to OMIA during the development of the training application so it would not require any special user rights to install. It will also discuss the unforeseen side benefits the Navy has realized beyond its original development intent. Design decisions included porting the OMIA to Java enabling deployment as both a portable stand-alone application for PC, Mac and Linux, as well as a web application that can be run through a web browser. Side benefits include the device being picked up by maintenance organizations, as they need to understand the cockpit as part of their activities. Currently, OMIA continues to benefit the Navy by providing training that can be accessed wherever and whenever it is needed, and thanks to this flexibility its use has expanded far beyond its original scope via ongoing funding. A recent capability expansion is the addition of sophisticated acoustics, whereby acoustics training previously only available in limited availability TOFT trainers is now available via the Acoustics Training System (ATS) version of OMIA.
