Data Word and Message Formats

1999-01-01
HISTORICAL
AS15532
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.

Processes for Engineering a System

1999-01-01
CURRENT
EIA632
The purpose of this Standard is to provide an integrated set of fundamental processes to aid a developer in the engineering or reengineering of a system. Use of this Standard is intended to help developers establish and evolve a complete and consistent set of requirements that will enable delivery of feasible and cost-effective system solutions; satisfy requirements within cost, schedule, and risk constraints; provide a system, or any portion of a system, that satisfies stakeholders over the life of the products that make up the system. provide for the safe and/or cost-effective disposal or retirement of a system.

Aerospace Hydraulic System Fluid Contamination - Location of Sampling Points

1999-01-01
CURRENT
ARP4268A
The scope of this Aerospace Recommended Practice (ARP) covers where, when, and how often to sample hydraulic system fluid on aerospace vehicles for particulate contamination measurements. The measurement of hydraulic fluid particulate contamination is of concern to the aerospace community because of the critical importance of hydraulic equipment reliability. Contamination is always present in the system fluid, even in new unused fluid. Contamination must be below a level that will not adversely affect system operation. This ARP draws from aerospace industry experience and practice to establish criteria for fluid contamination sampling recommendations in aerospace vehicle hydraulic systems. Fluid samples can then be subjected to measurement of particulate contamination and of other harmful contaminants such as chlorinated solvents and water.

Human Interface Criteria for Cockpit Display of Traffic Information

1999-01-01
CURRENT
ARP5365
This SAE Aerospace Recommended Practice (ARP) sets forth design and operational recommendations concerning the human factors issues and criteria for cockpit display of traffic information systems. The visual and aural characteristics are covered for both the alerting components and traffic depiction/situation components. The display system may contain any one or a combination of these components Although the system functionality assumed for this document exemplifies fixed-wing aircraft implementation, the recommendations do not preclude other aircraft types. The recommendations contained in this document address both near and far term technology directed toward providing in flight traffic awareness, although the present version remains primarily focused on near term applications. Since this document provides recommendations, the guidance is provided in the form of “should” statements as opposed to the “shall” statements that appear in standards and requirements.
