Design of ARINC661 data analysis software for airworthiness compliance verification

In this paper, a digital model library of ARINC661 protocol is constructed for ARINC661 data communication test verification requirements and airworthiness conformance verification requirements between cockpit display system (CDS) and user application (UA). Furthermore, the data analysis software based on airborne AFDX Network is developed, which realizes the automatic test of the correctness and integrality of ARINC661 data message. Fully considering the large amount of interaction data and complex interaction for ARINC 661 specification, the method of online data acquisition and monitoring and off-line analysis is used to achieve airworthiness compliance verification for CDS system design based on ARINC661.
