Avionics data visibility and storage
Aircraft manufacturers like Boeing Aircraft have adopted commercial-off-the-shelf Ethernet as the next-generation Aircraft Data Network (ADN) recording technology. Designers recognize today’s low-cost Ethernet as an optimal way to quickly and reliably move data between their product’s airborne-systems. This applies to flight-control signaling and passenger entertainment systems.
AFDX®/ARINC 664 Part 7 is one example of a deterministic, Quality of Service (QoS) ADN technology for both commercial-freight and passenger aircraft. Electronic systems that interface and utilize the AFDX® network are installed at various stages of its production cycle. Designers and builders understand the importance of monitoring the aircraft’s data-bus as avionics systems are brought online. The captured data is valuable for both system troubleshooting and design improvements.
However, the assembly of just one passenger plane could take from four to six weeks to complete. An ideal solution is a long-duration recording system that can capture bus-data from the start of the aircraft’s assembly until its completion. It’s an opportunity to archive critical data for future systems analysis.
