This SAE Aerospace Information Report (AIR) identifies Propulsion Engineer’s recommendations for the instrumentation that is required for the safe operation and maintenance of turbine engines as installed in helicopters. It should be used as a guide for cockpit layout, as well as a reference for maintenance considerations throughout the propulsion area. Propulsion instruments should receive attention early in the design phase of the helicopter. Maintenance and diagnostics recorders are not considered within the scope of this document. (See ARP1587, “Aircraft Gas Turbine Engine Monitoring System Guide”.)

This SAE Aerospace Standard (AS) applies to all temperature instruments used in aircraft applications and environments. The word “instrument” as used in this Standard encompasses only the display device and does not include the temperature sensors. Examples of the types of instruments covered are as follows:

This SAE Recommended Practice defines the test conditions, procedures, and minimum design requirements for nominal 6, 12, and 24 V turn signal, hazard warning, warning lamp alternating, and combination flashers.In the SAE manual there are four documents with requirements for flashers. These documents all follow the same form, the test procedures are the same and the performance requirements are very similar. This document will combine the procedures and performance requirements for the four into one document and, thus, supercede the following:SAE J590—Turn Signal FlashersSAE J945—Hazard Warning FlashersSAE J1054—Warning Lamp Alternating FlashersSAE J2068—Combination Turn Signal and Hazard Warning Flashers.The purpose in generating this document has been threefold, (a), to consolidate the four documents into one, (b), to harmonize the SAE documents with other international standards, (c), to include requirements for extended durability flashers in the SAE documents.The document accomplishes the intention completely.It should be noted that other international standards utilize one document which includes the requirements for all type of flashers. In addition, they include requirements for Class A and B durability or normal and extended durability.SAE J1690 compares favorably with the international documents except for one aspect. The international standards require a bulb outage indication should one occur. Although FMVSS-108 requires bulb outage for fixed load flashers, it does not for variable load flashers. Although with a small number of bulbs, it is possible to achieve bulb outage with a flasher, a system with a large number of bulbs requires additional capabilities to achieve bulb outage indication. As a result, a bulb outage indication requirement has never been included in SAE flasher documents. It may be possible in the future to include test procedures and requirements for bulb outage in revisions of this document.Although several of the existing flasher documents are SAE Standards, this document is being released as a Recommended Practice because of the inclusion of data (extended durability requirements) that have not as yet gained broad acceptance.Note—The task force developed this document which consolidated the existing documents into one which harmonizes with other international standards and which includes requirements for extended duty flashers, it recognizes there remains more to be accomplished. The present environment is considerably more hostile and at the same time more delicate than when the flasher documents were initially developed. The task force has been attempting to include requirement to insure environmentally friendly flashers. However, considering the need for a document with extended duty requirements, the task force decided it was more important to release the document in its present form and continue to work on the additional test procedures and requirements to satisfy the present and future environmental conditions.

This SAE Standard presents the minimum requirements for nonmetallic tubing with one or more layers manufactured for use as liquid-carrying or vapor-carrying component in fuel systems for gasoline, or alcohol blends with gasoline. Requirements in this document also apply to monowall tubing (one layer construction). When the construction has one or more layers of polymer-based compounds in the wall, the multilayer constructions are primarily for the purpose of improvement in permeation resistance to hydrocarbons found in various fuels. The tube construction can have a straight-wall configuration, a wall that is convoluted or corrugated, or a combination of each. It may have an innermost layer with improved electrical conductivity for use where such a characteristic is desired. The improved electrical conductivity can apply to the entire wall construction, if the tubing is a monowall. (For elastomeric based MLT constructions, refer to SAE J30 and SAE J2405).Unless otherwise agreed to by suppliers and users this document applies to tubing for any portion of the fuel system that might operate continuously at temperatures above −40 °C and below 90 °C and up to a maximum working gage pressure of 450kPa. The tubing can be used at the peak intermittent temperature up to 115 °C.This document can apply to systems that operate at higher pressures and/or are exposed to higher temperatures. For higher pressures, the acceptance criteria of section 7.2 must be correspondingly changed. For higher temperatures, the acceptance criteria of sections 7.2 and 7.14 remain the same, but apply at the higher temperature. The selection of higher temperatures and pressures that could be used for this document would be the decision of the end user and supplier of the specific fuel/fuel vapor system in question.There are three types of tubing covered by this specification, based on the type of application for which the tubing is intended to be used:High pressure, liquid fuel line is tubing that handles liquid fuel at pressures up to 450 kPa pressure, and can handle the maximum pressure requirements identified in sections 7.1 and 7.2. These are typically the smaller diameter tubes identified in Table A1.Low pressure, liquid fuel line is tubing that is regularly exposed to liquid fuel, but is subjected to pressures that are under 50 kPa (e.g. fuel filler pipes). These are typically the larger diameters identified in Table A1.Fuel vapor tubing is tubing that handles fuel in vapor form or some liquid condensed from vapor, and operates at a working gauge pressure that does not exceed 20 kPa.In some cases, a distinction is made in the criteria that apply to tubing used to carry liquid fuel compared to tubing used to carry fuel vapor. These are identified separately in each section.

This specification covers an electrolytic alkaline cleaner in the form of a water soluble powder.Updated technical content to be compatible with aerospace industry alkaline cleaning specifications and changed test method to replace 1,1,1-trichloroethane cleaning solvent with a more environmentally friendly solvent.

In 1941, the SAE Iron and Steel Division in collaboration with the American Iron and Steel Institute (AISI) made a major change in the method of expressing composition ranges for the SAE steels. The plan, as now applied, is based in general on narrower ladle analysis ranges plus certain product (check) analysis allowances on individual samples, in place of the fixed ranges and limits without tolerances formerly provided for carbon and other elements in SAE steels (reference SAE J408).ISTC Division 1 has developed a procedure which allows for the maintenance of the grade list in this SAE Standard. This will involve conducting an industry-wide survey to solicit input. This survey will be conducted at a frequency deemed necessary by the technical committee. Criteria have been established for the addition to or deletion of grades from the grade table. A new grade will be considered if it meets standard SAE grade ranges, has a minimum usage or production of 225 tonnes/year (250 tons/year), and has the endorsement of at least two users or producers. New steel compositions will still be considered as Potential Standard (PS) steels, based on the guidelines provided in SAE J1081, until such time as production of the new steel achieves a level of production or usage qualifying it for consideration as a standard steel.The deletion of a grade from the grade table will be by consensus based on the grade survey results. Deleted grades will be archived in SAE J1249 for future reference.The compositions in this document may apply to open hearth and basic oxygen, or electric furnace steels. Grades shown in Table 1 with prefix letter E are normally made by the electric furnace process with maximum limits of 0.025% phosphorus and 0.025% sulfur. The nominal chemical limits or ranges in the compositions given in Table 1 are subject to standard variations in check analysis given in SAE J409. Since AISI is no longer issuing steel grade designations, all grades listed in this document are SAE grades.

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.Describing the fuel and electrical energy usage of plug-in hybrid electric vehicles (PHEVs) is very challenging for the reason that these values vary greatly depending upon the distance traveled between charging. Detailed test procedures recommended for PHEVs are found within SAE J1711, this document serves to supply appropriate UF curves for the equations in that document that weigh the charge depleting mode operation with the charge-sustaining operation depending upon the charge-depleting mode distance measured from the test. The original issue of SAE J2841 introduced the Utility Factor based upon a mileage-based “Fleet” analysis of the US DOT National Household Transportation Survey data. This issue of SAE J2841 adds more options to the Utility Factor calculations by analyzing another data set from a Georgia Tech called the “Commute Atlanta” in order to find a vehicle-weighted analysis.

SAE J448, Surface Texture, has been set up for precision reference specimens using a controlled surface profile to obtain reproducible roughness values. These specimens are for instrument calibration. Appropriate symbols for roughness, waviness, and lay have also been standardized (ASA B46.1-1962 and SAE J448).For production control, especially from one geographical location to another, means are required to facilitate the inspection of surface characteristics called for by specifications which include not only roughness but profile waviness and lay. In order to integrate the requirements of the designer with the actual production of surfaces, a second grade of control standards must be adopted which will be functional in nature for the specific product being manufactured. These control standards may be Calibrated Pilot Specimens (actual parts with satisfactory texture) or Roughness Comparison Specimens (ASA B46.1-1962). This SAE Recommended Practice describes the usage of these control standards.This technology has not evolved significantly in several years therefore this document should be classified as stabilized

This SAE Aerospace Information Report (AIR) addresses procedures applicable to quantifying the emission of nonvolatile particulate matter at the exit plane of aircraft gas turbine engines. While both volatile and nonvolatile particulate matter (PM) are present in aircraft gas turbine exhaust, the methods used to measure nonvolatile particles are farther advanced and are addressed here.Existing PM measurement regulations employ the SAE Smoke Number measurement (Reference 2.1.1), a stained filter technique used in evaluating visible emissions. The environmental and human health issues associated with submicronic PM emissions require more detailed measurement of the mass, size, and quantity of these particle emissions.Responding to regulatory agency requests, this AIR describes measurement techniques that are well developed and could be applied to the measurement of aircraft engine particulate matter. The techniques discussed here are considered relevant for measuring particle parameters identified with environmental and health concerns.The discussion that follows is based on research made while developing measurement techniques and in scientific and engineering experiments regarding PM emissions. The techniques are not yet used in routine aircraft engine certification. Future use in regulatory testing is likely to involve further refinements in methodology and application. It is planned that these refinements will be included in the subsequent publication of an Aerospace Recommended Practice.The distinction between nonvolatile and volatile particle types is a critical task in the measurement of particles in aircraft engine exhaust. Appendix A, SAE E-31 Position Paper on Particle Matter Measurements, provides additional technical bases for the scope of this AIR. The measurement methods for volatile condensed particles in turbine exhaust will be covered in a subsequent report. Observations to date show that volatile particles occur mainly at diameters less than 10 nanometers (<10 nm) but may dominate in particle number density (PND).AIR5892A documents the non-volatile particulate matter (PM) measurement technologies that were mature and had aviation measurement experience as E-31 began its first steps in moving toward a non-volatile PM Aerospace Recommended Practice (ARP). In addition to documentation of these potential candidate measurement techniques, AIR5892A includes an appendix which discusses the context and approach that E-31 planned on using in developing a non-volatile PM ARP. For these reasons, it will be useful and important for future SAE documents to be able to cite AIR5892A as a review of measurement techniques and of the context for making non-volatile measurement decisions. Since no equivalent document exists in the archival technical literature, having a stable SAE AIR5892A document available for citation will be useful for the future development of the anticipated ARP and for the future application of this ARP once it is published.The International Civil Aviation Organization (ICAO) has a Committee on Aviation Environmental Protection (CAEP) that has great interest in the development of a non-volatile PM measurement methodology. CAEP has shown significant and specific interest in both AIRs and ARPs in the area of non-volatile PM measurement. As such, ICAO's CAEP would also benefit greatly from having a stabilized, citable version of AIR5892A available.
