A Guide to Aircraft Turbine Engine Vibration Monitoring Systems(Cancelled Jan 2017)
This Aerospace Information Report (AIR) is a general overview of typical airborne engine vibration monitoring (EVM) systems applicable to fixed or rotary wing aircraft applications, with an emphasis on system design considerations. It describes EVM systems currently in use and future trends in EVM development. The broader scope of Health and Usage Monitoring Systems, (HUMS ) is covered in SAE documents AS5391, AS5392, AS5393, AS5394, AS5395, AIR4174.
Rationale:The Aerospace Information Report (AIR) has been superseded by a completely new document, ARP1839, which provides guidance to aircraft turbine engine vibration monitoring systems. The original AIR1839C information was updated and transformed into ARP1839.
