THE USE OF AN IRIG-106 CHAPTER 10 RECORDER AS A TELEMETRY SYSTEM

Abstract

IRIG-106 Chapter 10 has become the recording standard for most of the new flight test programs and many of the current ongoing programs. The primary goal of the standard was to define a common format for recording 100% bulk data such as PCM, MIL-STD-1553 busses, Video/Audio, ARINC-429, Ethernet, IEEE-1394, Analog Data, and others. In most cases the standard has provided the instrumentation engineers and the data analysts with a recording solution that meets their needs. Many programs require transmission of safety of flight data from a subset of the data acquired by the recorder. This may include selected video/audio channels, selected avionics bus data, and others. This requirement presents a dilemma to the flight test engineer who must duplicate part of the system for telemetry. This paper discusses several applications in which the IRIG-106 Chapter 10 recorder can be used as a telemetry system. It will include the transmission of bulk MIL-STD-1553 data per IRIG-106 Chapter 8, transmission of multiple Video/Audio and PCM data channels, and transmission of selected avionics data per IRIG-106 Chapter 4.
