Health and Usage Monitoring Solutions (HUMS)

Health and Usage Monitoring System (HUMS) records the status of critical systems and components on aircrafts so that the early detection of progressive defects, is possible and thus rectification can be achieved before they have an immediate effect on operational safety.


The HUMS system uses sensors, distributed throughout the airframe and its components, linked to a central computer unit with a data recording and storage system. Monitoring trends in the recorded data is particularly important - it allows system specialists to determine whether the aircraft has developed faults that require rectification. The IVA HUMS collects usage parameters such as take-offs, landings, engine starts and winch lifts as well as a subset of engine and transmission health data. IVA has been an integral part in the research and development for the GTRE GTX-35VS Kaveri. The GTRE GTX-35VS Kaveri is an afterburning turbofan project developed by the Gas Turbine Research Establishment (GTRE), a lab under the Defence Research and Development Organisation (DRDO) in Bengaluru, India.
