SAE AIR4175

Description / Abstract: An effective GSS is vital to the successful implementation of an EMS and is a fundamental part of the total monitoring system design, including assest management. Unlike the on-board part of the EMS which principally uses real time data to indicate when engine maintenance is required, a GSS can offer much greater processing power to comprehensively analyze and manipulate EMS data for both maintenance and logistics purposes

This document reviews the main EMS functions and discusses the operating requirements used to determine the basics design of a GSS, including the interfaces with other maintenance or logistics systems. A brief discussion is also included the interfaces with other maintenance or logistic systems. A brief discussion is also included on some of the more recent advances in GSS technology that have been specifically developed to provide more effective diagnostic capabilities for gas turbine engines

Purpose:

The purpose of this AIR is to finally examine the role of a GSS for processing data as part of the overall EMS functionality. Secondly, it considers the role of a GSS in supporting both Customer and OEM total logistics management systems. Thirdly, this AIR will provide guidelines for the development and use of a GSS in an aircraft operational environment. Finally, this document addresses the program management requirements associated with the initial development and on-going support of a GSS
