Cost Versus Benefits of Engine Monitoring Systems
The purpose of this SAE Aerospace Information Report (AIR) is to provide information that would be useful to potential users/operators and decision makers for evaluating and quantifying the benefits of an Engine Monitoring Systems (EMS) versus its cost of implementation.<p> This document presents excerpts from reports developed to analyze "actual aircraft cost/benefits results". These are presented as follows:<p> a. First, to outline the benefits and cost elements pertaining to EMS that may be used in performing a cost versus benefits analysis.</br> b. Second, to present considerations for use in conducting the analysis.</br> c. Third, to provide examples of analyses and results as they relate to the user/operator and decision-maker community.<p> The document encompasses helicopters and fixed wing aircraft and distinguishes between civilian and military considerations.<p> This document is not intended to be used as a technical guide, nor is it intended to provide methodologies, be a legal document, or be a standard. The findings are informational and are presented in the words of the report authors.
The AIR has been superseded by a completely new document, ARP4176, which not only takes a different approach to cost and benefits of Engine Health Management, but also provides much more up-to-date information. The original AIR is, thus, out of date and of no value to readers. So, the document should be cancelled and not stabilized.
