Honeywell said its EVXP Health and Usage Monitoring System (HUMS) has been certified by the FAA and selected by Sikorsky Aircraft as a standard option for the S-76C helicopter. Honeywell said the system monitors aircraft vibration, engine and structural health and works with Honeywell ground support equipment and software to decrease maintenance costs and increase operational readiness. The system includes on-board sensors and a data processor to calculate specific maintenance solutions. In total, the system provides engine health and usage monitoring, exceedance monitoring and recording, power margin and automatic power assurance testing, performance trending, cycle counting, operational usage monitoring and flight data monitoring and recording.
