This specification covers a corrosion- and heat-resistant nickel alloy in the form of bars, forgings, flash-welded rings, and stock for forging or flash-welded rings.

This specification covers a magnesium alloy in the form of plate 0.250 to 6.000 inches (6.35 to 152.40 mm), inclusive, in nominal thickness (see 8.5).
AMS D Nonferrous Alloys Committee
This specification covers a nitriding grade of aircraft-quality, low-alloy steel in the form of bars, forgings, mechanical tubing, and forging stock. AMS6497 and AMS6498 cover UNS K23280 having other quality levels.

A-20A Crew Station Lighting
This SAE Aerospace Standard (AS) will specify what type of NVGs are required and minimum requirements for compatible crew station lighting, aircraft exterior lighting such as anti-collision lights, and position/navigation lights that are “NVG compatible.” Also, this document is intended to set standards for NVG utilization for aircraft so that special use aircraft such as the Coast Guard, Border Patrol, Air Rescue, Police Department, Medivacs, etc., will be better equipped to chase drug smugglers and catch illegal immigrants, rescue people in distress, reduce high-speed chases through city streets by police, etc. Test programs and pilot operator programs are required. For those people designing or modifying civil aircraft to be NVG compatible, the documents listed in 2.1.3 are essential.
A-20A Crew Station Lighting
This SAE Standard applies to mobile, construction-type lifting cranes utilizing cantilevered boom crane structures and associated jibs (see Figure 1).
Cranes and Lifting Devices Committee
As part of this work, the accuracy requirements for the road friction coefficient estimation of a friction-adaptive automatic emergency braking (AEB) system are determined using a complex, nonlinear vehicle model. The AEB system varies its trigger distance depending on an estimated value of the road friction coefficient. The accuracy requirements are determined at a driving speed of 40 km/h depending on the severity classification of ISO 26262 in the statistically relevant Euro NCAP test scenario with a stationary target vehicle. MATLAB/Simulink is used as simulation software. The permissible estimation error (difference between estimated value and road friction coefficient) is determined by the severity classification S1 (light and moderate injuries). The results show that the positive permissible estimation error (road friction coefficient is overestimated) must not exceed about 30% of the road friction coefficient to comply with the severity classification S1 of ISO 26262.

This specification covers materials in the form of a liquid used to remove smut from aluminum surfaces treated with etch-type oxidation and corrosion removers.
AMS J Aircraft Maintenance Chemicals and Materials Committee
This standard specifies the communications hardware and software requirements for fueling hydrogen surface vehicles (HSV), such as fuel cell vehicles, but may also be used where appropriate with heavy-duty vehicles (e.g., buses) and industrial trucks (e.g., forklifts) with compressed hydrogen storage. It contains a description of the communications hardware and communications protocol that may be used to refuel the HSV. The intent of this standard is to enable harmonized development and implementation of the hydrogen fueling interfaces. This standard is intended to be used in conjunction with the hydrogen fueling protocols in SAE J2601 and nozzles and receptacles conforming with SAE J2600 and ISO 17628. It may also be used with future hydrogen fueling protocols at the discretion of those fueling protocols.
Fuel Cell Standards Committee
This method is designed to evaluate the coking propensity of synthetic ester-based aviation lubricants under two phase air-oil mist conditions as found in certain parts of a gas turbine engine, for instance, bearing chamber vent lines. Based on the results from round robin data in 2008 to 2009 from four laboratories, this method is currently intended to provide a comparison between lubricants as a research tool; it is not currently a satisfactory pass/fail test.
E-34 Propulsion Lubricants Committee
This specification covers a standard acrylonitrile butadiene (NBR-H) rubber stock with medium-high acrylonitrile content in the form of molded test slabs.
AMS CE Elastomers Committee
This specification covers an aluminum alloy in the form of die forgings, hand forgings, and rolled rings 4 inches (102 mm) and under in nominal thickness and forging stock of any size (see 8.6).
AMS D Nonferrous Alloys Committee
This specification covers steel cleanliness requirements for aircraft-quality ferromagnetic steels, other than hardenable corrosion-resistant steels (refer to AMS2303), by magnetic particle inspection methods. This specification contains sampling, specimen preparation, inspection procedures, and cleanliness rating criteria (see 8.2).
AMS E Carbon and Low Alloy Steels Committee
This specification covers an aluminum alloy in the form of wire, sheet, foil, pig, grains, shot, and chips (see 8.6).
AMS D Nonferrous Alloys Committee
This specification covers quality assurance sampling and testing procedures used to determine conformance to applicable material specifications of corrosion- and heat-resistant steel and alloy forgings.
AMS F Corrosion and Heat Resistant Alloys Committee
This specification covers steel cleanliness requirements for special aircraft-quality ferromagnetic steels, including hardenable corrosion-resistant steels, by magnetic particle inspection methods. This specification contains sampling, sample preparation, inspection procedures, and cleanliness rating criteria (see 8.2).
AMS E Carbon and Low Alloy Steels Committee
This SAE Standard establishes the minimum construction and performance requirements for seven conductor 1/8-2/10-4/12 cable for use on trucks, trailers, and converter dollies for 12 VDC nominal applications. Where appropriate, the standard refers to two types of cables (Type F and S, described later in the standard), due to the variation in the performance demands of cables used in flexing and stationary applications. While the document’s title refers to ABS Power to differentiate the document from the SAE J1067 standard that it supersedes, the scope applies to both the primary green cable for powering ABS and lighting and the yellow auxiliary cable of the same construction.
Truck and Bus Electrical Systems Committee
This SAE Standard establishes the minimum performance requirements for electrical distribution systems for use in dollies and trailers in single or multiple configurations for 12 VDC nominal applications.
Truck and Bus Electrical Systems Committee
This SAE Recommended Practice specifies the design and/or evaluation with the specific equipment, conditions, and methods for distributorless battery ignition systems intended for use in various internal combustion engines including automotive, marine, motorcycle, and utility engine applications. The test procedures listed in this document are limited to measurements performed on a test bench only and do not include measurements made directly on engines or vehicles. This standard is not intended to supply information for battery ignition systems used in aircraft applications of any type.
Ignition Standards Committee
Oil consumption is a major concern for all engine manufacturers, both from an environmental and engine durability standpoint. Understanding how oil consumption is affected by key design parameters has traditionally been established during the validation phase of an engine development program using both steady-state and transient lube oil consumption (LOC) measurements. Cost and time pressures are driving this development to be performed virtually, where many more parameters can be assessed and understood prior to design verification testing. This paper presents a new analytical method that is capable of predicting transient phenomena of the ring pack that would not normally be captured by steady-state methods, providing a toolset that reduces engine development testing and cost and aid troubleshooting. Implemented in Realis1 RINGPAK, this new transient method has been validated against transient LOC measurements for a 2.0 L 4-cylinder GTDI engine. Different transient load/speed
