      The current paradigm for data acquisition and recording systems for flight test applications does not meet today's demand for high reliability and timing performance. Such systems are better served through a network-based approach that can provide the capacity at which systems must acquire, record, process, and telemeter data. As with any complex system, this approach does have challenges. This paper describes the methods used to develop a network-centric flight test system, including simulators, IEEE 1588 time synchronization, network message protocols, and addresses the integration issues involved such as network topology and reliable latency-bounded throughput. Solutions used in overcoming these integration issues in previous system designs are also presented.
