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, installed at various stages of its production cycle. Designers and builders understand the importance of monitoring the aircraft’s data-bus as they bring online the avionics systems. 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.

  • A long-duration Ethernet/AFDX/ ARINC 664 recording solution.
    • Commercial and freight aircraft can take several weeks to build while recording data.
  • An Ethernet recorder that captures and stores 100% of the data.
    • AFDX® is designed for the assured transmission of all data. It is just as important that ALL data is recorded.
  • A flexible and open recorder solution.
    • Recorded data should be in a standard format so that power analysis tools can access and utilize the stored data.

Applications

  • Avionics systems troubleshooting
  • Protocol analysis
  • Bus-data simulation (playback)
  • Data logging
  • Data display

Many capable data-bus tools aid in the development, troubleshooting, and maintenance of an aircraft’s avionics systems. For example, Abaco Systems offer a powerful software suite, complete with deep avionics analytics and including test and simulation capabilities.

These software tools generally feature a graphical user interface (GUI) with an optional Windows®-hosted API or Linux operating systems. Both the engineer and the technician can then present bus-data in multiple forms. One can be a simple message-based displays of raw data. Onother can be an advanced visualizations, like graphic analog gauges and strip charts.

Such software typically interfaces directly with the aircraft for realtime analysis and limited logging capability. However, a full-rate data recorder is better. Especially when a real-time operation of an aircraft is not convenient or feasible. Archived data from a previous operation is very valuable. It can be exported or played back as it was originally captured to the recorder’s disk-based volume(s).

A conventional bus analysis tool should not notice the difference between recorded data and actual data from a running aircraft.

Several leading aircraft manufacturers chose daqscribe’s DDR70-Mini-20G  for long-duration AFDX®/ARINC664 (via Ethernet) recording. The product features 100% Ethernet packet capture, single-system storage capacities up to 30TB, and a remarkably easy-to-use operations GUI.
