AS15531A
This SAE Aerospace Standard (AS) contains requirements for a digital time division command/response multiplex data bus, for use in systems integration, that is functionally equivalent to MIL-STD-1553B with Notice 2. Even with the use of this document, differences may exist between multiplex data buses in different system applications due to particular application requirements and the options allowed in this document. The system designer must recognize this fact and design the multiplex bus controller (BC) hardware and software to accommodate such differences. These designer selected options must exist to allow the necessary flexibility in the design of specific multiplex systems in order to provide for the control mechanism, architectural redundancy, degradation concept, and traffic patterns peculiar to the specific application requirements.

SAE J1939-81 Network Management defines the processes and messages associated with managing the source addresses of applications communicating on an SAE J1939 network. Network management is concerned with the management of source addresses and the association of those addresses with an actual function and with the detection and reporting of network related errors. Due to the nature of management of source addresses, network management also specifies initialization processes, requirements for reaction to brief power outages and minimum requirements for ECUs on the network.

AIR4271A
This Aerospace Information Report (AIR) has been prepared by the Systems Applications and Requirements Subcommittee of SAE Committee AS-2. It is intended to provide guidance primarily, but not exclusively, for specifiers and designers of data communication systems for real time military avionics applications within a platform. The subject of high speed data transmission is addressed from two standpoints: (1) the influence of developments in technology on avionics architectures as a whole and (2) the way in which specific problems, such as video, voice, closed loop control, and security may be handled. While the material has been prepared against a background of experience within SAE AS-2 relating to the development of a family of high speed interconnect standards, reference to specific standards and interconnect systems is minimized.

AS15532A
The emphasis in this standard is the development of data word and message formats for AS15531 or MIL-STD-1553 data bus applications. This standard is intended as a guide for the designer to identify standard data words and messages for use in avionics systems and subsystems. These standard words and messages, as well as the documentation format for interface control document (ICD) sheets, provide the basis for defining 15531/1553 systems. Also provided in this standard is the method for developing additional data word formats and messages that may be required by a particular system but are not covered by the formats provided herein. It is essential that any new word formats or message formats that are developed for a 15531/1553 application follow the fundamental guidelines established in this standard in order to ease future standardization of these words and messages. The standard word formats presented represent a composite result of studies conducted by the U.S.

The purpose of this document is to establish the requirements for Real-Time Communication Protocols (RTCP). Systems for real-time applications are characterized by the presence of hard deadlines where failure to meet a deadline must be considered a system fault. These requirements have been driven predominantly, but not exclusively, by aerospace type military platforms and commercial aircraft, but are generally applicable to any distributed, real-time, control systems. These requirements are primarily targeted for the Transport and Network Layers of peer to peer protocols, as referenced in the Open System Interconnect Reference Model (2.2.1 and 2.2.2), developed by the International Standards Organization (ISO). These requirements are intended to complement SAE AS4074 (2.1.1) and AS4075 (2.1.2), and future SAE communications standards.

This report on quantification of Essentiality (W) and Utilization (U) terms extends the scope of the basic expression for system effectiveness (Es = ADC) to include the additional "W" and "U" paramenters needed for the quantification of multi-functioned and multi-missioned systems. Methods and procedures for applying these terms to system effectiveness quantification are discussed and simple examples to demonstrate the principles of usage are included. The need to look at the system being quantified in terms of its level in the mission/function hierarchical tree is explained. The relationships between system elements (hardware, software, and personnel) and performance functions are discussed and illustrated with examples. Two methods for applying the "W"'and "U" weight factors, LOGIC AND (weak link model) and LOGIC OR (degraded operational modes model) are described and examples are shown for these cases.

Fibre Channel is the primary avionics bus on many modern military aircraft. It is also the defined High-Speed bus for MIL-STD-1760E weapons applications. Profiled Ethernet networks are the primary avionics bus in many commercial aircraft and Commercial Ethernet is an ever increasing presence in modern military aircraft as well. This network standard is a convergence of Fibre Channel and Ethernet into a unified network standard which will provide a seamless approach to integrating end systems from either technology into a merged network structure. This work is based upon the commercial data storage market industry’s work on the Converged Data Storage Network or FCoE (Fibre Channel over Ethernet). This effort will look at profiling the FCoE work done in the commercial industry and adding information where necessary to affect a networking standard that will seamlessly integrate end systems from Commercial Ethernet, Fibre Channel, or FCoE enhanced devices.

This SAE Aerospace Standard (AS) establishes guidelines for the use of IEEE-1394b as a data bus network in military and aerospace vehicles. It encompasses the data bus cable and its interface electronics for a system utilizing S400 over copper medium over extended lengths. This document 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 does not identify specific environmental requirements (electromagnetic compatibility, temperature, vibration, etc.); such requirements will be vehicle-specific and even LRU-specific. However, the hardware requirements and examples contained herein do address many of the environmental conditions that military and aerospace vehicles may experience. One should reference the appropriate sections of MIL-STD-461E for their particular LRU, and utilize handbooks such as MIL-HDBK-454A and MIL-HDBK-5400 for guidance.
