ARINC 664 Training Information



Crucial Knowledge currently has three ARINC 664-related courses available or in development. We also offer an 8-hour ARINC 429 Theory and Troubleshooting, which is a prerequisite for the ARINC 664-I & II training.


Ethernet/ARINC 664-I: A one day introductory course for students who will be involved in testing and troubleshooting of ARINC 664 based systems or equipment. This is the digital information transfer system used on the Airbus A380 and Boeing 787 aircraft. The course includes an overview of Ethernet equipment and theory, including the OSI 7 layer model, and the operational features of repeater hubs, bridges and routers. MAC protocol is covered along with a detailed description of Ethernet Frames. Full and half duplex Ethernet, different modulation schemes such as 4B/5B, Ethernet flow control, Pause operation, and Auto negotiation are covered. Part 2 of the ARINC 664 is reviewed, focusing on redundancy concepts, Integrity checking, abnormal bit transfers, link details, link budgets, and link calculations. Also covered are test procedures, cable characteristics, cable parameters, implementation guidelines and test equipment.


ARINC 664-II: A one day follow-on course to Ethernet/ARINC 664-I. This course focuses on Part 7 of the A664 specification. Topics covered in this course are the 7 layers of OSI as it applies to AFDX, TCP, UDP, IP and End System addressing. Allowable primitive data formats are defined and explained along with data message structures. The guidelines for ARINC 429 to AFDX formatting are presented and discussed along with an introduction and overview of testing recommendations for an AFDX system.


ARINC 664-III: A one day course covering fiber optics. This course is currently under development, with an anticipated availability date of mid- to late 2009.


NOTE: Students taking Ethernet/ARINC 664 I & II, should previously have taken the eight-hour ARINC 429 course or have a thorough knowledge of ARINC 429.
