This SAE Aerospace Information Report (AIR) examines the need for and the application of a power train usage metric that can be used to more accurately determine the TBO for helicopter transmissions. It provides a formula for the translation of the recorded torque history into mechanical usage. It provides examples of this process and recommends a way forward. This document of the SAE HM-1 IVHM Committee is not intended as a legal document and does not provide detailed implementation steps, but does address general implementation concerns and potential benefits.
This ARP provides insights on how to perform a cost benefit analysis (CBA) to determine the return on investment that would result from implementing an integrated Health Management (HM) system on an air vehicle. The word “integrated” refers to the combination or “roll up” of sub-systems health management tools to create a platform centric system. The document describes the complexity of features that can be considered in the analysis, the different tools and approaches for conducting a CBA and differentiates between military and commercial applications. This document is intended to help those who might not necessarily have a deep technical understanding or familiarity with HM systems but want to either quantify or understand the economic benefits (i.e., the value proposition) that a HM system could provide. Prognostics is a capability within some HM systems that provides an estimation of remaining useful life (RUL) or time to failure and so Prognostic Health Management (PHM) is used where this predictive element exists.

Defining technology maturity and application risk b. Cost benefit analysis (Value analysis) c. Selection of system components d. Selection of technology e.
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.
This SAE Aerospace Recommended Practice (ARP) outlines the design and functional requirements for aircraft passenger lifts, operated manually and self-propelled.

This SAE Aerospace Recommended Practice (ARP) is intended to recommend a minimum standard, for the design and manufacturer of a self-propelled, chassis mounted passenger boarding vehicle. The vehicle will permit safe operation while minimizing aircraft damage and personnel safety hazards associated with commercial aircraft boarding operations. The vehicle described is intended to be used for assisting wheelchair passengers and passengers with disabilities on and off aircraft with door sill heights of 60 in (152.4 cm) and above.

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.

This SAE Aerospace Recommended Practice (ARP) provides best practices and guidance for creating an architecture for integrated vehicle health management systems. Where possible, this document will also provide references to tools to conduct architectural trades. Finally, this document will provide use cases to expose considerations and stakeholders to be included in these trades and utilization of an IVHM system (which may lead to new functional or non-functional requirements).
This Recommended Practice outlines the electrical performance characteristics for a continuous duty, diesel or gasoline engine driven brushless alternator unit for supplying 400-Hertz electrical power to commercial transport aircraft. It is intended to assist the airlines in standardizing recommendations for various sizes and configurations of equipment and it is a guide for the preparation of detailed specifications. The unit is primarily intended to supply power to the aircraft during passenger loading and unloading, and during servicing operations. The combination of the equipment specified herein and the interconnecting cables(s) between the 400-Hertz alternator and the aircraft shall provide power characteristics at the aircraft receptacle which meet MIL-STD-704 requirements for Category "B" equipment. Other limits which are necessary to meet specific conditions must be specified by the purchaser.
This SAE Aerospace Information Report (AIR) is broken into various categories for convenience and ease of identification. It is the purpose of this document to provide certain criteria for the design and selection of stairways, for the boarding of passengers onto an aircraft. The criteria presented are limited to those factors which affect the safety of the passengers and are coordinated, where applicable, with the practices of the architectural profession, with respect to the design of stairways. Comprehensive design requirements for passenger stairs can be found in the industry documents listed under 2.1.3, 2.1.4, and 2.1.5 hereafter. The recommended practices are applicable to both mobile variable-elevation type stairways and to fixed-elevation stairways of the type built into an aircraft fuselage.

This Aerospace Recommended Practice (ARP) was created to help industry deal with existing barriers to the successful implementation of Integrated Vehicle Health Management (IVHM) technology in the aerospace and automotive sectors. That is,given the common barriers that exist, this ARP can be applied not only to aerospace but also to the automotive, commercial and military vehicle sectors. Original Equipment Manufacturers (OEMs) in all of these sectors are heavily dependant upon a large number of component suppliers in order to design and build their products. The advent of IVHM technology has accentuated the need for improved coordination and communication between the OEM and its suppliers –to ensure that suppliers design health ready capabilities into their particular components. The goal is to provide uniform requirements, practices and methods to address the sharing and application of component IVHM design information and the need for efficient real-time communication of health state data in running vehicles.
