      Network-based instrumentation systems are rapidly replacing traditional fixed serial interconnected instrumentation in both commercial and military flight test environments. Modern network-based flight test systems are composed of large numbers of devices including high-speed network switches, data acquisition devices, recorders, telemetry interfaces, and wireless network transceivers, all of which must be managed in a coordinated fashion. Management of the network system includes configuring, controlling, and monitoring the health and status of the various devices. Configuration by hand is not a realistic option, so algorithms for automatic management must be implemented to make these systems economical and practical. This paper describes the issues that must be addressed for managing network-based flight test systems and describes a network management approach that was developed and employed to manage a large-scale network-based flight test system.

      Some of the first applications of network-based data acquisition systems have been for large aircraft. These systems contained numerous network nodes including data acquisition units, switches, recorders, network management units, and others. One of the desirable aspects of a networked-based system is the ability to scale such a system to meet increasing test requirements. Similarly, these systems lend themselves to scaling down, as well, to meet the testing needs of smaller test articles. These needs may include fewer nodes and/or physically smaller components. The testing of smaller vehicles places slightly different requirements on the testing process. In general, there is a greater need for real-time analysis, flexibility and ad-hoc testing. This paper will attempt to show how a small to medium sized test article can benefit from the same powerful, feature-rich network-based data acquisition and recording system as used on larger programs. The paper will also show how a smaller system can deliver on this promise without sacrificing performance and functionality.
