AbstractBoeing Commercial Airplane Group’s Flight Test Engineering organization is developing a new test data recording format to be used on the new model 777 airplane. ARINC 429, ARINC 629 and IRIG PCM data will be formatted for recording test data. The need to support a variety of data recorders, and three types of data, mandate the development of a new recording format. The format Flight Test chose is a variation of IRIG Standard 106-86, Chapter 8. The data from each channel is treated as a data packet, including time and channel ID, and then multiplexed into 24 bits. This allows a time accuracy of 10 microseconds and a minimum latency caused by multiplexing.
