This SAE Aerospace Recommended Practice (ARP) is a system guide for Engine Monitoring System (EMS) definition and implementation. This keystone document addresses EMS benefits, capabilities, and requirements. It includes EMS in-flight and ground applications consisting of people, equipment, and software. It recommends EMS requirements that are a balance of selected benefits and available capabilities. This ARP purposely addresses a wide range of EMS architecture. The intent is to provide an extensive list of possible EMS design options.

NOTE:

a

Section 3

describes an EMS.

b

Sections 4 and 5

outline benefits and capabilities that should be considered for study purposes to define EMS baselines for how much engine monitoring is required.

c

Section 6

provides implementation requirements that should be considered for an EMS after study baseline levels of EMS complexity are selected.
