This SAE Aerospace Standard (AS) establishes the requirements for the use of IEEE-1394b as a data bus network in military and aerospace vehicles. It defines the concept of operations and information flow on the network. As discussed in 1.4, this specification contains extensions/restrictions to “off-the-shelf” IEEE-1394 standards, and assumes that the reader already has a working knowledge of IEEE-1394.
This document is referred to as the “base” specification, containing the generic requirements that specify data bus characteristics, data formats and node operation. It is important to note that this specification is not stand-alone - several requirements provide only example implementations and delegate the actual implementation to be specified by the network architect/integrator for a particular vehicle application. This information is typically contained in a “network profile” slash sheet that is subservient to this base specification. In a similar manner, the electrical characteristics of the bus media, as well as connector information is contained in a “physical layer” slash sheet, that also may be unique to a particular vehicle application.
In summary, full understanding of this specification requires knowledge of IEEE-1394b standards and access to the physical layer slash sheets and the slash sheets and handbook for the target application.
Rationale
AS5643A has been reaffirmed to comply with the SAE five-year review policy.
The SAE AS-1 Aircraft Systems & Systems Integration committee addresses all facets of aircraft avionics systems¿design, maintenance, and in-service experience. It reviews and develops specifications for stores interface, validation requirements, systems integration, mission store validation plans and media terminal design. Also addressed are system test requirements, architecture, security and 1553 data bus standards. The group is comprised of three subcommittees dedicated to creating, preparing, and maintaining all relevant specifications, standards, and requirements for aircraft avionics systems. These subcommittees include:
AS-1A Avionics Networks
AS-1B Aircraft-Store Integration
AS-1C Avionic Subsystems
Participants in the SAE AS-1 committee include OEMs, suppliers, aircraft avionics equipment companies, consulting firms, government and others across the aerospace and defense industries.
* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.

Search Tips: Search Operators:AND, OR, NOT; Wild Cards; Using Quotes
SAE MOBILUS® Search Tips
Please note: All terms not contained within quotes, will be evaluated using the OR operator. This means that your search results will contain all results that contain ANY of the entered terms.
AND, OR, NOT
SAE MOBILUS supports the use of the AND, OR and NOT BOOLEAN operators ONLY function with the Advanced Search.
Wild Cards
Using the asterisk, ( * ) allows you to search for a partial word. For example, entering a keyword search of aero* will search for any word beginning with aero.
Using the question mark, ( ? ) allows you to search for a word with a single character wildcard. For example, searching for t?re would match both tire and tyre
Using Quotes
Words in double quotes " " are treated as a phrase. Conducting a search for "heat model" will return all results in which the exact phrase "heat model" is found, while "heat modeling" would NOT be included.
A term combined with a phrase will be joined with an OR operator.
Searching for Standards
When searching for a standard please use the entire Document Number assigned, which includes the abbreviation. A space can be used, or omitted between the abbreviation and number.
