A Methodology for Quantifying the Performance of an Engine Monitoring System

2017-10-13
HISTORICAL
AIR4985
The purpose of this SAE Aerospace Information Report (AIR) is to present a quantitative approach for evaluating the performance and capabilities of an Engine Monitoring System (EMS). The value of such a methodology is in providing a systematic means to accomplish the following: 1 Determine the impact of an EMS on key engine supportability indices such as Fault Detection Rate, Fault Isolation Rate, Mean Time to Diagnose, In-flight Shutdowns (IFSD), Mission Aborts, and Unscheduled Engine Removals (UERs). 2 Facilitate trade studies during the design process in order to compare performance versus cost for various EMS design strategies, and 3 Define a “common language” for specifying EMS requirements and the design features of an EMS in order to reduce ambiguity and, therefore, enhance consistency between specification and implementation.

A Review of Literature on the Relationship Between Gas Turbine Engine Lubricants and Aircraft Cabin Air Quality

2016-09-12
CURRENT
AIR5784
There has been a recent upsurge in interest from the media concerning the quality of the environment within aircraft cabins and cockpits especially in the commercial world1-4. This has included (although by no means been limited to) the air quality, with particular reference to the alleged effects of contamination from the aircraft turbine lubricant. Possible exposure to ‘organophosphates’ (OPs) from the oil has raised special concerns from cabin crew. Such is the concern that government organisations around the world, including Australia, USA and UK, have set up committees to investigate the cabin air quality issue. Concern was also voiced in the aviation lubricants world at the way in which OP additives in turbine lubricants were being blamed in some reports for the symptoms being experienced by air crew and passengers. SAE Committee E-34 therefore decided that it should gather as much available information on the subject as possible.

AEROSPACE GLOSSARY FOR HUMAN FACTORS ENGINEERS

2008-02-16
HISTORICAL
ARP4107
This Glossary is designed to serve persons who need to know the accepted meanings, within specific contexts, of the terminology used in reports, articles, regulations, and other materials dealing with aviation safety -- with particular reference to terms specific to human factors in aviation safety. It is assumed that some users of the Glossary will be familiar with the nomenclature of aviation, but will need information on the language of human factors in engineering as they apply to aviation safety. Others (for example, engineers and psychologists) will have fairly extensive knowledge of the terminology of their own and related disciplines, but will need authoritative definitions of technical terms specific to aviation. Within the foregoing general framework, the following guidelines for the inclusion of terms to be defined have been observed:

AGE CONTROL OF AGE SENSITIVE ELASTOMERIC MATERIALS

1975-05-01
HISTORICAL
AIR1364
This report summarizes data and background relative to age control of specific classes of those nitrile type synthetic elastomers used in sealing devices which are resistant to petroleum base hydraulic fluids, lubricating oils and aircraft fuels. This includes, but is not limited to, those nitrile (NBR or BUNA-N) elastomers specifically covered by Section I of MIL-STD-1523.

AGRICULTURAL TRACTOR TEST CODE (OECD) EQUIVALENT TO ORGANISATION FOR ECONOMIC CO-OPERATION AND DEVELOPMENT C(87)53

1993-04-01
HISTORICAL
J2708_199304
The purpose of this SAE Standard is to define test conditions, describe tests to be made, specify data to be obtained, show formulas and calculations, define terms, and establish a uniform method of reporting so that performance data obtained on various makes and models of tractors, tested in accordance with this document, will be comparable regardless of where the tests are made. Because of the availability of many tractor models and types that can be equipped with a variety of special or optional equipment, the scope of this document must be limited to obtaining and reporting only the most significant of widely used performance data. Tests performed to either the Standard Code as outlined in Section 5 or the Restricted Code as outlined in Section 6 will satisfy requirements of this Agricultural Tractor Test Code. This document is technically equivalent to the OECD Tractor Test Code C(87)53, Annex I and Annex II.
