AIR4652A
This SAE Aerospace Information Report (AIR) covers handicapped passenger boarding devices used airside to transfer handicapped passengers between the terminal building and the aircraft. It provides an elevating platform to facilitate access to the aircraft; it does not cover devices for in-terminal or streetside transfers, wheelchairs for on-board aircraft or in-terminal usage, or aircraft boarding bridges. However, it should be recognized that for many handicapped passengers, a boarding chair is necessary for the lifting operation and movement to the passenger's seat inside the aircraft cabin. Such wheelchairs are widely used in larger aircraft, and the Federal Aviation Agency has developed a performance specification for a boarding chair for commuter aircraft.

ARP5120
SAE ARP 5120 provides recommended best practices, procedures, and technology to guide the physical and functional development, integration, verification, and validation of highly reliable Engine Health Management System (EHMS) for gas turbine engines, including aircraft engines and Auxiliary Power Units (APUs). This ARP also serves as a concise reference of considerations, approaches, activities, and requirements for producing the end-to-end engine health monitoring system comprised of both on and off-board subsystems for the sensing, acquisition, analysis, detection, and data handling functions of an EHMS. These functions and related maintenance activities promote engine safety. These functions may also be used to effect continued operation or return to service decisions when demonstrated as compliant with the applicable airworthiness requirements defined by the responsible Aviation Authority. Where practical, this document delineates between military and commercial practices.

GEIAHB0007B
This handbook is intended to provide additional information on the use and tailoring of the data in GEIA-STD-0007. The standard provides a new approach to Logistics Support Analysis Record (LSAR) (i.e., MIL-STD-1388-2B) data with emphasis on data transfer (e.g., XML Schemas) versus data storage (e.g., relational tables). GEIA-STD-0007 identifies the range of logistics product data that is generated during the development and acquisition of a system or end item. It does not prescribe the supportability analyses required to generate logistics product data. How the data is generated via analysis techniques/tools, how it is stored and processed, and how the data is used to generate specific logistics support products, is left to the performing activity. GEIA-STD-0007 is a data transfer standard implementing the logistics data concepts of GEIA-STD-927, Common Data Schema for Complex Systems.

For the purposes of this document, LTS is defined as any device storage for more than 12 months but typically much longer. While intended to address the storage of unpackaged semiconductors and packaged electronic devices, nothing in this standard precludes the storage of other items under the storage levels defined herein.

Packaged Electronic Devices. Electronic Devices are defined as any packaged electrical, electronic, electro-mechanical (EEE) item, or assemblies using such items. This standard is intended to ensure that adequate reliability is achieved for devices in user applications after long term storage. Users are encouraged to request data from suppliers to this specification that demonstrates a successful storage life requested by the user.

J2842
The intent of this standard is to establish a framework to assure that all evaporators for R-744 and R-1234yf mobile air conditioning (MAC) systems meet appropriate testing and labeling requirements. SAE J639 requires vehicle manufacturers to perform assessments to minimize reasonable risks in production MAC systems. The evaporator (as designed and manufactured) shall be part of that risk assessment and it is the responsibility of the vehicle manufacturer to assure all relevant aspects of the evaporator are included. It is the responsibility of all vehicle or evaporator manufacturers to comply with the standards of this document at a minimum. (Substitution of specific test procedures by vehicle manufactures that correlate well to field return data is acceptable.) As appropriate, this standard can be used as a guide to support risk assessments.

ARP5757A
This SAE Aerospace Recommended Practice (ARP) provides guidance for substantiating the airworthiness of aircraft engine components. Generally these components are associated with the engine control system, the system or systems that allow the engine to provide thrust or power as demanded by the pilot of the aircraft while also ensuring the engine operates within acceptable operating limits. But these components may also include hardware and systems associated with engine lubrication, engine or aircraft hydraulic or electrical systems, aircraft environmental control systems, thrust reverser control, or similar aircraft or engine propulsion system functions. This paper develops the concept of using a 26 item matrix of environmental conditions for evaluating aircraft engine component airworthiness. This approach is compatible with current practices used in the industry and has been accepted by engine certification authorities as part of engine certification programs.

J2772
This Standard is restricted to refrigeration circuits that provide air-conditioning for the passenger compartments of passenger and commercial vehicles. This Standard includes analytical and physical test procedures to evaluate concentration inside the passenger compartment. In the early phases of vehicle evaluation, usage of the analytical approach may be sufficient without performing physical tests. The physical test procedure involves releasing refrigerant from an external source to a location adjacent to the evaporator core (inside the HVAC-Module). An apparatus is used to provide a repeatable, calibrated leak rate. If the system has multiple evaporators, leakage could be simulated at any of the evaporator locations. This standard gives detail information on the techniques for measuring R-744 [CO2] and R-1234yf [HFO-1234yf], but the general techniques described here can be used for other refrigerants as well.

Information for input to the risk assessment is provided in the Appendices of this document. This information should not be considered to be complete, but only a reference of some of the data needed for a complete analysis of the risk associated with the use of refrigerants in MAC systems.
