This SAE Aerospace Information Report (AIR) describes procedures for use in the field to determine if 115/200 Volt, 400 Hz aircraft external electrical power connectors are excessively worn, which may result in the inability of the external power plug to be retained, intermittent electrical performance and arcing.

The intent of this specification is for the procurement of the material listed on the QPL and, therefore, no qualification or equivalency threshold values are provided. Users that intend to conduct a new material qualification or equivalency program shall refer to the Quality Assurance section of this base specification, AMS3961. All material qualification and equivalency data has been archived and is available for review upon request. Contact the CMH-17 Secretariat (www.cmh17.org) for additional information.

This SAE Recommended Practice which defines the terms and tabulates the limits of the characteristics for various protective devices used in conjunction with 400-cycle ground power for civil aircraft is intended to assist the airlines in standardizing on 400-cycle protective systems. The limits found to be acceptable in the civil aircraft industry are presented.

Shortly after World War II, as aircraft became more sophisticated and power-assist, flight-control functions became a requirement, hydraulic system operating pressures rose from the 1000 psi level to the 3000 psi level found on most aircraft today. Since then, 4000 psi systems have been developed for the U.S. Air Force XB-70 and B-1 bombers and a number of European aircraft including the tornado multirole combat aircraft and the Concorde supersonic transport. The V-22 Osprey incorporates a 5000 psi hydraulic system. The power levels of military aircraft hydraulic systems have continued to rise. This is primarily due to higher aerodynamic loading, combined with the increased hydraulic functions and operations of each new aircraft. At the same time, aircraft structures and wings have been getting smaller and thinner as mission requirements expand. Thus, internal physical space available for plumbing and components continues to decrease.

This SAE Information Report represents an information report on a conceptual ITS architecture and its accompanying protocols from the perspective of Advanced Traveller Information Systems providers and users. While a specific logical and physical architecture for ITS is still in the development stages, this conceptual architecture provides a robust general view of ITS functions and interfaces.

This dictionary of terms was prepared for use by those with a need to describe and understand the dynamics and handling of two-wheeled, single track vehicles. It is intended to span the gap between vehicle dynamics specialists and those with a more general interest. This report is pertinent to such areas as vehicle design and development, the description of two-wheeler properties, rider training and education, and the preparation of standards and regulations. This report was prepared by the SAE Motorcycle Committee, which solicits suggestions for improvements and additions to be considered in future revisions. Comments should be directed to SAE Headquarters.

The factors involved in the selection of a quick-disconnect are grouped into the following classifications for the purpose of discussion: (a) Functional considerations. (b) Weight considerations. (c) Environmental performance factors. (d) End fitting types. (e) Additional considerations.

This Aerospace Information Report (AIR) is a general overview of typical airborne vibration monitoring (AVM) systems with an emphasis on system hardware design considerations. It describes AVM systems currently in use. The purpose of this AIR is to provide information and guidance for the selection, installation, and use of AVM systems and their elements. This AIR is not intended as a legal document but only as a technical guide.

An effective ground station is vital to the successful implementation of an EMS and is a fundamental part of the total monitoring system design. Unlike on-board processing systems which principally use data to indicate when engine maintenance is required, ground stations offer much greater processing power to analyse and manipulate EMS data more comprehensively for both maintenance and logistics purposes. This document reviews the main EMS functions and discusses the operating requirements which will determine the basic design of a ground station, including the interfaces with other maintenance or logistics systems. A brief discussion is also included on some of the more recent advances in EMS ground station technology which have been specifically developed to provide more effective diagnostic capabilities for gas turbine engines. Finally, this document addresses the program management requirements associated with the initial development and on-going support of a ground station.
