ARP4912C
This SAE Aerospace Recommended Practice (ARP) provides recommendations on cavity design, the installation of elastomer type spare seals in these cavities, and information surrounding elastomer material properties after contact with typical shock absorber hydraulic fluid(s) or grease. This ARP is primarily concerned with the use of spare seals on shock absorbers where only a single dynamic seal is fitted and in contact with the slider/shock absorber piston at any one time. These shock absorbers typically have a spare (dynamic) seal gland located on the outer diameter of the lower seal carrier. This spare seal gland is intended to house a spare elastomer contact seal. Split Polytetrafluoroethylene (PTFE) backup rings can also be installed in the spare seal cavity. During operation, if the fitted dynamic shock absorber standard seal begins to fail/leak, then the aircraft can be jacked up, allowing the lower gland nut of the shock absorber to be dropped down.

ARP6950
This SAE Aerospace Recommended Practice (ARP) provides guidance and interpretation on how to apply the objectives and activities in ARP4754A, “Guidelines for Development of Civil Aircraft and Systems”, to propulsion systems with electronic engine control. As the ARP4754A was developed and written more generally at the aircraft level, guidance will be provided to allocate ARP4754A objectives and activities to each side of the aircraft/engine interface. Using this guidance, certification applicants (aircraft and engine manufacturers) will be able to make proposals to coordinate their activities with their respective authority based on this allocation with the objective of distributing efficiently the compliance demonstration efforts between engine and aircraft certification and of avoiding unnecessary duplication of work.

EIAIS632
This standard defines a total system approach for the development of systems. The standard requires: establishing and implementing a structured, disciplined. and documented systems engineering effort incorporating the systems engineering process; multidisciplinary teamwork; and the simultaneous development of the products and processes needed to satisfy user needs. The systems engineering process is defined generically to facilitate broad application. This standard defines the requirements for technical reviews. The tasks in this standard provide a methodology for evaluating progress in achieving system objectives. This standard provides a comprehensive, structured, and disciplined approach for all life-cycle phases, including new system product and process developments, upgrades, modifications, and engineering efforts conducted to resolve problems in fielded systems.

EIAIS731_1
The purposeo f this Interim Standard is to support the development and improvement of systems engineering capability. The scope of this standard includesa ll activities that associate with or enable systems engineering. Systems engineering is an inter-disciplinary approach and means to enable the realization of successful systems. In this context, systems engineering is not limited to what either Systems Engineering organizations or Systems Engineers do. Rather it is the interaction of many people, processes, and organizations resulting in the accomplishment of the required activities.

This volume is the second in a series of monographs which will make the standard (ANSUEIA 548-1988) easier to understand. It is intended to be used as a companion to the EDIF Reference Manual Version 2.0.0, which is also published by the EL4 (ISBN 0-7908-0000-4). This volume gives an introduction to the concept of connectivity in the format. Concepts are explained in a general way; constructs, such as net, appear in italics throughout this volume. Whenever more detail is desired about a topic the italicized constructs should be consulted in the EDIF Reference Manual. The EDIF Reference Manual contains the official definition of the format and should always be taken as the authoritative source of information. Further application guides will be provided in later volumes of this series.

The increase in the number of silicon foundries and CAD/CAE system and workstation companies, and the problem of movement of data among in-house design systems has made a standard interchange format for electronic design data essential. The benefits of the general adoption of a standard interchange format are important and far reaching. The customer receives a much wider variety of feasible choices, and free competition in both CAEYCAD system/tool businesses and foundry businesses is enhanced. The electronic circuit designer and customer of CAE/CAD system and foundry service can expect compatibility among these products. The designer can choose equipment and services best suited for a particular task with a minimum of overhead. Foundries can work with customers regardless of the CAE/CAD equipment that the customer is using.

This document offers some conventions for the use of EDIF in transfer applications involving schematic designs. It discusses the use of EDIF 2 0 0 constructs that apply to the SCHEMATIC view. This document does not attempt to cover the use of EDIF for the transfer of all design aspects, It is intended to be a starting point for implementing EDIF schematic translators. It is not an EDIF user manual. It is not an amendment to the EDIF 2 O O Recommended Standard ANSIIEIA-548, which contains the official definition of the format and should always be taken as the authoritative source of EDIF information. This document assumes you are familiar with schematic capture systems but not familiar with EDIF. You will need to refer to EIA-548 for detailed definitions of some of the constructs discussed below.

Program Managers have considered the subject of effectiveness quantification from three diverse points of view. The first viewpoint, in conjunction with the system effectiveness analyst, is to quantify everything and to consider everything quantifiable into a figure of merit. The result is a numerical decision aid that usually has some undesirable attributes such as oversimplification, non-sensitivity to critical parameters, hidden calculations, and difficulty in exercise of the model. This technique is characterized by mathematical models, computer programs, and attempted optimizations. The second viewpoint, in conjunction with the controller, is to consider the effectiveness as specified and concentrate on cost reduction, This has a danger of formulating all technical problems in terms of cost or economic considerations. This technique is characterized by closely controlled work packages.

The CDIF Family of Standards is primarily designed to be used as a description of a mechanism for transferring information between CASE tools. It facilitates a successful transfer when the authors of the importing and exporting tools have nothing in common except an agreement to conform to CDIF. The language that is defined for the Transfer Format also has applicability as a general language for ImportExport from repositories. The CDIF Integrated Meta-model defined for CASE also has applicability as the basis of standard definitions for use in repositories.
