This document establishes the minimum training and qualification requirements for ground-based aircraft deicing methods and procedures. All guidelines referred to herein are applicable only in conjunction with the applicable documents. Due to aerodynamic and other concerns, the application of deicing fluids shall be carried out in compliance with engine and aircraft manufacturers’ recommendations. The scope of training should be adjusted according to local demands. There are a wide variety of winter seasons and differences of the involvement between deicing operators, and therefore, the level and length of training should be adjusted accordingly. However, the minimum level of training shall be covered in all cases. As a rule of thumb, the amount of time spent in practical training should equal or exceed the amount of time spent in classroom training.

This document includes best practices and guidance related to the specification of the information that must be exchanged between the functional layers in the IVHM system or between lower-level components/subsystems and the higher-level control system to enable health monitoring and tracking of system degradation severity. The intent is to provide an IVHM system that can robustly report the degradation of a given
The importance of reliability in design engineering has significantly grown since the early 1960’s. Competition has been a primary driver in this growth. The three realities of competition today are: world class quality and reliability, cost-effectiveness, and fast time-to-market. Formerly, companies could effectively compete if they could achieve at least two of these features in their products and product development processes, often at the expense of the third. However, customers today, whether military, aerospace, or commercial, have been sensitized to a higher level of expectation and demand products that are highly reliable, yet affordable. Product development practices are shifting in response to this higher level of expectation. Today, there is seldom time, or necessary resources to extensively test, analyze, and fix to achieve high quality and reliability. It is also true that the rapid growth in technology prevents the accumulation of historical data on the field performance
This SAE standard establishes the requirement for suppliers to plan a reliability program that satisfies the following three requirements: a. The supplier shall ascertain customer requirements b. The supplier shall meet customer requirements c. The supplier shall assure that customer requirements have been met
SAE JA6097 (“Using a System Reliability Model to Optimize Maintenance”) shows how to determine which maintenance to perform on a system when that system requires corrective maintenance to achieve the lowest long-term operating cost. While this document may focus on applications to Jet Engines and Aircraft, this methodology could be applied to nearly any type of system. However, it would be most effective for systems that are tightly integrated, where a failure in any part of the system causes the entire system to go off-line, and the process of accessing a failed component can require additional maintenance on other unrelated components.
This SAE Standard provides a framework for the management of software reliability within system reliability requirements. It is based around the Software Reliability Plan and Software Reliability Case and emphasizes the importance of evaluating progress towards meeting software reliability requirements throughout the project life-cycle.
In 1994 the SAE G-11 Reliability, Maintainability, Supportability, and Logistics (RMSL) Division chartered a software committee, G-11SW, to create several software standards and guidance documents across the RMSL spectrum, including a software supportability program standard. The committee was formed as a cross section of international representatives from commercial industries and governments. The G-11SW committee has attempted to develop a standard that is consistent with a SAE G-11 system level supportability program standard and augmented by necessary software-specific support information. The G-11SW committee believes this document reflects the best current commercial practices, and meets the objectives of the United States Department of Defense Acquisition Reform initiative. This document is performance based and is intended to be used by industries to address market demands for supportable software products that facilitate system evolution, time to market, and implementation of
In 1994, the SAE G-11 Reliability, Maintainability, Supportability and Logistics (RMSL) Division chartered a software committee, G-11SW, to create several software standards and guidance documents across the RMSL spectrum, including a software reliability program standard and implementation guidelines. The committee was formed as a cross section of international representatives from commercial industries and governments. The G-11SW committee has developed a standard (JA1002) and these implementation guidelines (JA1003) that are consistent with a SAE G-11 system level reliability program standard (JA1000) and guidelines (JA1000-1), augmented by necessary software-specific information. The G-11SW committee believes these documents reflect the best current commercial practices, and meet the objectives of the United States Department of Defense Acquisition Reform initiative and the North Atlantic Treaty Organization (NATO) Reliability Program. The JA1002 program standard is intended to be
This document identifies recommended practices for the implementation of a supportability program for software within an overall systems engineering framework. Guidelines for implementation of a Software Supportability Plan and associated Software Supportability Case are presented. Recommended practices are described for establishing a software supportability program through selection of life cycle activity tasks tailored for the application. Recommended models and process methods to achieve the life cycle activity tasks are briefly reviewed and/or referenced. The recommended practices are applicable to all projects incorporating software. The target audience for this document includes software acquisition organizations, logisticians, developers, supporters, and customers. This document is intended to be guidance for business purposes and should be applied when it provides a value-added basis for the business aspects of development, use, and sustainment of support-critical software.
Historically, the supportability aspects of software have been given a very low priority in the overall program requirements. This was particularly prevalent during the acquisition phase, where funding and timing constraints were usually the top priorities. The result was inadequate product supportability, inadequate support funding, lack of good field data, and no meaningful analysis and optimization of possible support alternatives. In order to alleviate these historical concerns, this document presents a top-level structured overview of an overall software support concept and the information associated with it. This document was developed by the Supportability Subcommittee of the Society of Automotive Engineers (SAE) G-11 Reliability, Maintainability, Supportability, and Logistics (RMSL) Software Committee (G-11SW). G-11SW and its different Subcommittees plan to develop several more detailed reports that together will form an integrated task guide for analyzing software
