This SAE Aerospace Recommended Practice (ARP) recommends a methodology to be used for the design, analysis and test evaluation of modern helicopter gas turbine propulsion system stability and transient response characteristics. This methodology utilizes the computational power of modern digital computers to more thoroughly analyze, simulate and bench-test the helicopter engine/rotor system speed control loop over the flight envelope. This up-front work results in significantly less effort expended during flight test and delivers a more effective system into service. The methodology presented herein is recommended for modern digital electronic propulsion control systems and also for traditional analog and hydromechanical systems.
This standard is for use by organizations that procure and integrate EEE Parts. These organizations may provide EEE Parts that are not integrated into assemblies (e.g., spares and/or repair EEE Parts). Examples of such organizations include, but are not limited to, the following: Original Equipment Manufacturers; contract assembly manufacturers; maintenance, repair, and overhaul (MRO) organizations; and suppliers that provide EEE Parts or assemblies as part of a service. These requirements are intended to be applied (or flowed down as applicable) through the supply chain to all organizations that procure and integrate EEE Parts and/or systems, subsystems, or assemblies. The mitigation of Counterfeit EEE Parts in this standard is risk based. These mitigation steps will vary depending on the criticality of the application and desired performance and reliability of the equipment/hardware. The requirements of this document are used in conjunction with the organization’s higher-level
The scope of this SAE Recommended Practice is restricted to the testing of original equipment on passenger vehicles and to provide for a uniform industry test procedure.
This specification covers a carbon steel in the form of sheet and strip.
This specification covers quality assurance sampling and testing procedures used to determine conformance to applicable material specification requirements of wrought carbon and low-alloy steel products and of forging stock.
Thrust measurement systems come in many sizes and shapes, with varying degrees of complexity, accuracy and cost . For the purposes of this information report, the discussions of thrust measurement will be limited to axial thrust in single-axis test systems.
This SAE Aerospace Recommended Practice (ARP) establishes the minimum recommended Test Stand Setup and Procedures for inspecting and testing Aircraft Refuelers. The inspection and test procedure shall be used to evaluate the operation and performance of an Aircraft Refueler to assure that it meets the minimum refueling performance criteria and is fit for aircraft fueling and/or defueling operations. These procedures shall be used to test new Aircraft Refuelers and may be used to perform routine tests to confirm that the Aircraft Refuelers comply with the minimum performance criteria as specified herein. This document covers all types of Aircraft Refuelers, stationary (e.g., cabinet type units) or mobile (e.g., hydrant service vehicles, tankers, etc.).
This document presents minimum criteria for the design and installation of LED passenger reading light assemblies in commercial aircraft. The use of “shall” in this specification expresses provisions that are binding. Non-mandatory provisions use the term “should.”
This specification covers an aircraft-quality, low-alloy steel in the form of bars, forgings, mechanical tubing, and forging stock.
A bolt-load retention (BLR) test is a practical test to determine the bolt load of a fastener joint with time and at given temperatures. There are three types of BLR tests described in this standard, namely general-purpose test, design-purpose test, and screening material test. A general-purpose BLR test may be used for screening materials, while a design-purpose BLR test is usually used to verify the BLR behavior of a specific joint. The screening material test is an example of the general-purpose test for typical automotive applications.
This specification, in conjunction with the general requirements for steel heat treatment covered in AMS2759, establishes the requirements for heat treatment of low-alloy steel parts to minimum ultimate tensile strengths of 220 ksi (1517 MPa) and higher. Parts are defined in AMS2759. The requirements for heat treatment of alloy Aermet100 are no longer part of this specification and can be found in AMS2759/3. Due to the limited hardenability of these materials, size limits have been added to this specification.
This SAE Recommended Practice has been adopted by SAE to specify: a A basis for net engine retarder power rating b Reference inlet air test conditions c A method for correcting observed engine retarder power to reference conditions d A method for determining net engine retarder power with a dynamometer
This document provides a recommended electrical performance testing guideline for LIBM, which makes up an xEV (Battery Electric Vehicles and Hybrid Electric Vehicles) battery pack system. This testing guideline may also be used for other applications, such as stationary, vessel, and aircraft. However, using the guideline for other applications should be determined by the users of this document. Users of this document may also be interested in conducting tests on battery cells and/or battery packs. To avoid conducting potentially redundant tests between cells, modules, and packs, this document does not specify which tests need to be conducted. Determination of which tests need to be conducted is at the user’s discretion and should be based on individual module applications. Rather than specifying which tests need to be conducted, this document describes how each test is to be conducted. This document provides a matrix of tests that can be selectively picked for the application
This document recommends design criteria for an Automatic Braking System. The ABS shall enhance braking performance under most aircraft configurations and all runway conditions.
This SAE Standard was developed to provide a method for indicating the direction of engine rotation and numbering of engine cylinders. The document is intended for use in designing new engines to eliminate the differences which presently exist in industry.

The marine environment differs greatly from other environments in which hydraulics are used. This Recommended Practice provides hydraulic design considerations and criteria for the marine environment and is applicable to commercial vessels, military ships, and submersible vehicles. This document may be used for manned and un-manned vehicles.
This Aerospace Information Report (AIR) outlines the design considerations and criteria for the control of water carryover from the environmental control system (ECS) with respect to causes and indicated corrective or preventative action. In addition, condensation on structure will be reviewed with possible preventative action described.
This Aerospace Standard (AS) 5659/4 Physical Layer Specification provides guidance for the physical layer of optical networks which use Wavelength Division Multiplexing (WDM), within the AS5659 WDM LAN specification document family. The physical layer consists of the optical interconnections between the functional components of the network. Performance requirements for general interconnections are described. For guidance, standards are identified, corresponding to each of several environments, which describe physical layer design, installation, maintenance, and training.
