AbstractDramatic increases in telemetry data rates and sources require test engineers to view and digest real-time data in order to make cogent decisions about whether to continue or modify flight tests. Traditional telemetry systems offer limited insight through a myriad of strip charts and alphanumeric displays. Attempts to improve this human interface employed expensive central superminicomputers and display systems. Although these methods have been successful, development and procurement costs and delays have limited their deployment. Recent advances in low-cost standard display, processing, and network technology have led to the development of the System 500. The System 500 employs a distributed architecture. Independent, relatively low cost, high-resolution color graphics workstations connect to the data acquisition and processing subsystems via Ethernet.* Each station is independent, requesting and then receiving only data for display. The combined ability to physically display and update only a few hundred parameters, each at relatively few samples per second makes Ethernet and standard upper layer protocols ideal for this application. The state-of-the-art human interface lets users select or mix a variety of methods to create and modify display contents, including: choosing from a list using arrow keys or a mouse, moving a scroll bar to pan through parameter files, or entering commands via keyboard where response anticipation reduces keystrokes to those uniquely defining a choice. A repertoire of graphic window displays is available to present real-time and static data concisely in analog and alphanumeric formats. Window size, location, and color have been chosen to focus attention rather than beautify. Standard windows and accent colors direct user attention to specific areas without cluttering and distracting.
