ITC/USA 2007 Conference Proceedings / The Forty-Third Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2007 / Riviera Hotel & Convention Center, Las Vegas, Nevada / The F-22 flight test program used a traditional distributed data acquisition system and a non IRIG-106 Chapter 10 recording system for its flight test program. In addition, it required a separate and very large Harris DAU system to monitor and record avionic data buses carrying secure data. Due to the size, cost, and the obsolescence of the Harris DAU system and components, Lockheed evaluated replacement systems. TTC proposed to develop F-22 specific Fiber Optic avionics bus monitors and an avionics PCM Data Selector / Encoder as part of its distributed IRIG-106 Chapter 10 Multiplexer / Recorder system to replace the Harris DAU. This replacement system challenges the traditional system approach used in many flight test programs. This paper describes the evolutionary process to design two independent distributed data acquisition and recording systems handling data with different classification levels. The data separation is maintained by way of system wiring, proper hardware that holds no residual data once power is removed, different transmission channels, hardware-based message blocking, and a separate IRIG-106 Chapter 10 multiplexing / recording system.
