Networked Flight Test Instrumentation Data Recording Solutions

Abstract

An integral component of networked Flight Test Instrumentation (FTI) and Health and Usage Monitoring Systems (HUMS) is the networked Data Recorder. The high data rates achievable in networked data acquisition systems put increased demands on the recorder to support ever faster read and write rates. Key to the success of the networked recorder is the format in which the data is recorded. The data recording file format should be network-centric with a low processing overhead to support the recording demands. In this paper the popular file formats, Chapter 10 and the Packet CAPture (PCAP), that are used for recording networked FTI are analyzed and compared.
