This document presents criteria for flight deck controls and displays for Airborne Collision Avoidance Systems.
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 specification covers an aluminum alloy in the form of sheet 0.040 to 0.249 inch (1.02 to 6.32 mm) in nominal thickness (see 8.7).
This Surface Vehicle & Aerospace Recommended Practice offers best practices and a methodology by which IVHM functionality relating to components and subsystems should be integrated into vehicle or platform level applications. The intent of the document is to provide practitioners with a structured methodology for specifying, characterizing and exposing the inherent IVHM functionality of a component or subsystem using a common functional reference model, i.e., through the exchange of design-time data and the application of standard vehicle data communications interfaces. 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
This document details one of the connections of the SAE J3105 document. The connections are referenced in the scope of the main document SAE J3105. SAE J3105/3 details the enclosed pin and sleeve connection. All the common requirements are defined in the main document; the current document provides the details of the connection. This document covers the main safety and interoperability relevant requirements for an electric vehicle power transfer system using a conductive automated charging device based on an enclosed pin and socket design. To allow interoperability for on-road vehicles (in particular, buses and coaches), one configuration is described in this document. Other configurations may be used for non-standard applications (for example, mining trucks or port vehicles).
The intent of this document is to develop a recommended practice for PEV chargers, whether onboard or off-board the vehicle, that will enable equipment manufacturers, vehicle manufacturers, electric utilities, and others to make reasonable design decisions regarding power quality. The three main purposes are as follows: 1 To identify those parameters of a PEV battery charger that must be controlled in order to preserve the quality of the AC service. 2 To identify those characteristics of the AC service that may significantly impact the performance of the charger. 3 To identify values for power quality, susceptibility, and power control parameters that are based on current U.S. and international standards. These values should be technically feasible and cost effective to implement into PEV battery chargers. SAE J2894/2 will describe the test methods for the parameters/requirements in this document.
This SAE Recommended Practice establishes the communication for the variety of potential functions for plug-in electric vehicle (PEV) customers. This includes features for use case items in SAE J2836/3 that may be PEV/customer optional equipment, such as AC vehicle-to-load (V2L) and AC vehicle-to-vehicle systems. These systems conform to SAE J1772 with variations required to identify to the PEV bidirectional onboard charger (OBC) the mode of operation changes and output requirements. SAE has published multiple documents relating to PEV and vehicle-to-grid (V2G) interfaces. The various document series are listed below, with a brief explanation of each. Figure 1 shows the sequencing of these documents and their primary function (e.g., the SAE J2836 and SAE J2847/1 documents start with smart charging, SAE J2836 and SAE J2847/2 then add DC charging, etc.). The intent is to have subsequent slash sheets complement each other as more functions and features are included. The /6 series of
SAE J2293 establishes requirements for Electric Vehicles (EV) and the off-board Electric Vehicle Supply Equipment (EVSE) used to transfer electrical energy to an EV from an Electric Utility Power System (Utility) in North America. This document defines, either directly or by reference, all characteristics of the total EV Energy Transfer System (EV-ETS) necessary to insure the functional interoperability of an EV and EVSE of the same physical system architecture. The ETS, regardless of architecture, is responsible for the conversion of AC electrical energy into DC electrical energy that can be used to charge the Storage Battery of an EV, as shown in Figure 1. The different physical ETS system architectures are identified by the form of the energy that is transferred between the EV and the EVSE, as shown in Figure 2. It is possible for an EV and EVSE to support more than one architecture. This document does not contain all requirements related to EV energy transfer, as there are many
This document is to be used as a checklist by curriculum developers to create courses or training for critical composite repair, maintenance, and overhaul issues. This document will not take the place of courses or training requirements for specific job roles of a composite repair technician, inspector, or engineer.
This SAE Information Report provides test methods and determination options for evaluating the maximum wheel power and rated system power of vehicles with electrified vehicle powertrains. The scope of this document encompasses passenger car and light- and medium-duty (GVW <10000 pounds) hybrid-electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), battery electric vehicles (BEVs), and fuel-cell electric vehicles (FCEVs). These testing methods can also be applied to conventional ICE vehicles, especially when measuring and comparing wheel power among a range of vehicle types. This document version includes a definition and determination methodology for a rated system power that is comparable to traditional internal combustion engine power ratings (e.g., SAE J1349 and UN ECE R85). The general public is most accustomed to “engine power” and/or “motor power” as the rating metric for conventional and electrified vehicles, respectively. Wheel power will always be a lower-power
This SAE Information Report establishes a set of “Utility Factor” (UF) curves and the method for generating these curves. The UF is used when combining test results from battery charge-depleting and charge-sustaining modes of a Plug-in Hybrid Electric Vehicle (PHEV). Although any transportation survey data set can be used, this document will define the included UF curves by using the 2001 United States Department of Transportation (DOT) “National Household Travel Survey” and a supplementary dataset.
SAE J3108 Recommended Practice (RP) provides fuel and hazard guidance for first and second responders of incidents associated with alternative fueled vehicles. The intent of SAE J3108-1 is to present responders with a limited number of intuitive letters and colors. The International community is in the process of adopting International Standards Organization (ISO) 17840, which provides first and second responders with a standardized format for emergency information. While the ISO 17840 format in coloring and lettering can be adopted and should be encouraged when possible, it is intended for large and heavy vehicles. SAE J3108-1 provides a means for responders to recognize fuel and vehicle type on North American light duty vehicles due to size constraints preventing use of ISO 17840 labels.1 While encouraged to be adopted or referenced by vehicle manufacturers, this RP has been developed for the use of States and other Governmental bodies. The RP is not intended to replace the standards
The SAE J2954 standard establishes an industry-wide specification that defines acceptable criteria for interoperability, electromagnetic compatibility, EMF, minimum performance, safety, and testing for wireless power transfer (WPT) of light-duty plug-in electric vehicles. The specification defines three charging levels up to 11 kVA and in future revisions up to 22 kVA. A standard for WPT based on these charge levels enables selection of a charging rate based on vehicle requirements, thus allowing for better vehicle packaging and ease of customer use. This is meant to be used in conjunction with communications standard SAE J2847/6 and use cases J2836/6 and ground assembly WPT Certification UL 2750. The specification supports home (private) charging and public wireless charging. In the near term, vehicles that are able to be charged wirelessly under SAE J2954 should also be able to be charged conductively by SAE J1772 plug-in chargers. This standard addresses stationary light-duty
This SAE Technical Information Report (TIR) establishes the instructions for the documents required for the variety of potential functions for PEV communications, energy transfer options, interoperability, and security. This includes the history, current status, and future plans for migrating through these documents created in the Hybrid Communication and Interoperability Task Force, based on functional objective (e.g., [1] If I want to do V2G with an off-board inverter, what documents and items within them do I need, [2] What do we intend for V3 of SAE J2953, …).
This information report provides an overview of a typical high voltage electric propulsion vehicle (xEV) and the associated on-board safety systems typically employed by OEM’s to protect these high voltage systems. The report aims to improve public confidence in xEV safety systems and dispel public misconceptions about the likelihood of being shocked by the high voltage system, even when the vehicle has been damaged. The report will document select high voltage systems used for xEV’s and describe safety systems employed to prevent exposure to the high voltage systems.

The following terminology has been generated by the ATA/IATA/SAE Commercial Aircraft Composite Repair Committee (CACRC) and provides terminology for design, fabrication, and repair of composite and bonded metal structures.
This SAE Recommended Practice is intended to describe the application of single-phase DC to AC inverters, and bidirectional inverter/chargers, which supply power to ac loads in Class heavy duty on-highway trucks (10K GVW). The document identifies appropriate operating performance requirements and adds some insight into inverter selection. This document applies to factory and after-market installed DC-to-AC inverter systems (Including inverter chargers) providing up 3000 W of 120 VAC line-voltage power as a convenience for operator and passenger use. Such inverters are intended to power user loads not essential to vehicle Operation or safety (e.g., HVAC, TV, microwave ovens, battery chargers for mobile phones or laptop computers, audio equipment, etc.). Systems incorporate the inverter itself as well as the input, output, control, and signal wiring associated with the inverter. Requirements are given for the performance, safety, reliability, and environmental compatibility of the system
