This SAE Information Report is a summary of information obtained by way of survey conducted during the 2Q and 3Q of 1997 of MAYDAY system manufacturers. The data represented here has been condensed from the original survey that was conducted by telephone interviews and faxes. The information contained within is limited to technical data as it pertains to vehicle and on-board MAYDAY system operations. It does not contain business, marketing, or any proprietary technical information. The complete survey results are in the possession of the SAE. The purpose of this survey was to determine whether the general concept and architecture on which the SAE J2313 MAYDAY Message Set was being developed is consistent with those of current MAYDAY system hardware manufacturers. The survey was not intended for MAYDAY service providers or public service answer points and emergency service providers. Further studies, perhaps by organization such as NENA or APCO, may be necessary to develop a complete

This procedure incorporates test cycles that produce relative fuel economy data relating to long haul, short haul, and local driving patterns, or any combination of these and to those components developed to improve fuel economy for these patterns. The tests conducted on a specific vehicle are to reflect that vehicle's general mode of operation. The procedure is intended to be used under controlled, warmed-up conditions on a test tract or on suitable roads. A minimum of two vehicles running simultaneously is required. Test condition recommendations are provided for undertaking this engineering test. If it is necessary to conduct a test outside of these test conditions, the purpose of the test and the variant conditions should be recorded and noted whenever the results are reported.

The electrical cranking system components, which include the battery, cables, and cranking motor, must be carefully selected to provide the necessary speed to start an engine under the most severe climatic conditions for which the system is intended. Engine cranking loads increase with cold temperatures, therefore, the initial selection of these components needs to consider low-temperature engine torque requirements. To insure an adequate electrical cranking system is obtained, it is important that proper test procedures are used for obtaining the cranking load requirements of the engine.

This document is intended to give advisory information for the selection of plain bearings and bearing materials most suitable for aircraft landing gear applications. Information included herein was derived from bearing tests and service experience/reports. Airframe/landing gear manufacturers, commercial airlines, the U.S. Air Force and Naval Air Systems Command provided input for the document. Information is given on bearing installation methods and fits that have given satisfactory performance and service life. Base metal corrosion is a major cause of problems in bearing installations for landing gears. Therefore, methods of corrosion prevention are discussed. Effort is directed toward minimizing maintenance and maximizing life expectancy of landing gear bearings. Lubricated and self-lubricating bearings are also discussed. There are wide ranges of bearing load and motion requirements for applications in aircraft landing gears. For this reason, it is the responsibility of the

This SAE Information Report provides test methods and determination options for evaluating the maximum wheel power and rated system power of vehicles with electrified vehicle powertrains. The scope of this document encompasses passenger car and light- and medium-duty (GVW <10000 pounds) hybrid-electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), battery electric vehicles (BEVs), and fuel-cell electric vehicles (FCEVs). These testing methods can also be applied to conventional ICE vehicles, especially when measuring and comparing wheel power among a range of vehicle types. This document version includes a definition and determination methodology for a rated system power that is comparable to traditional internal combustion engine power ratings (e.g., SAE J1349 and UN ECE R85). The general public is most accustomed to “engine power” and/or “motor power” as the rating metric for conventional and electrified vehicles, respectively. Wheel power will always be a lower-power
