This paper describes our experience in using a multimedia project management and software engineering environment, Decision-based Hyper-multimedia CASE (DHC), to support the Low-Visibility Landing and Surface Operations (LVLASO) project at the NASA Langley Research Center.1 The purpose of the LVLASO project is to allow pilots to land and taxi airplanes when visibility is impeded due to adverse weather conditions. NASA is supporting this effort by developing new software and hardware for use on the flight deck. We are utilizing DHC to capture the decisions and documents generated during this project's life cycle. DHC supports a new Decision-based Systems Development paradigm, which allows the organization of the project by the decisions which shape the end-products and associated documents. The experiences summarized in this paper demonstrate the value of a hyperlinked multimedia project space in developing large, group collaborative projects.

1 Low Visibility Landing and Surface Operations (LVLASO) Project

The Low Visibility Landing and Surface Operations (LVLASO) Project was recently initiated as part of the Terminal Area Productivity (TAP) program at NASA. The goal of the LVLASO project is to enhance pilots' abilities to land and taxi their planes when visibility is impeded due to adverse weather conditions. New hardware and software tools are being developed for this purpose; for example, a new axi-map" display will be placed in the airplane's cockpit. This new display will show the pilot (in real-time) the position of the plane on the runway or taxiway, and will allow the pilot to guide the plane along even if he or she cannot see out of the cockpit windows.
