data directly off of the aircraft’s various data busses,” explained Norman Baker, Director of Vehicle Health Products and Services, GE Aviation. “IVHM consists of a health management unit and a wireless data network unit. The health management unit monitors the sensors already on the various aircraft systems, including engines, avionics, cabin and other systems.” “The health management system’s open architecture actually monitors 10,000 individual aircraft parameters during flight,” he said. “It looks for not only faults, but also trends so we can proactively predict problems.” Baker explained that after the aircraft lands, the IVHM automatically identifies the best way to connect the aircraft via WiFi or cellular back to the Ground Services Network (GSN) to deliver a real-time picture of the aircraft’s health back to Gulfstream and the aircraft’s operator.
“They now have access to critical information about their aircraft
Predictive Maintenance Goes all Next-Gen As aircraft mature, that learned information about each aircraft’s specific needs is going to become even more critical on today’s digital aircraft than on older ‘analog’ airplanes. But, while you may not be able to see if a digital connector or sensor is going bad, there’s an increasingly good chance it will be able to tell you. That’s the goal of GE Aviation’s new Integrated Vehicle Health Management (IVHM) technology and service that is being introduced on the new Gulfstream G650. The IVHM system will power Gulfstream’s PlaneConnect HTM (Health & Trend Monitoring) System.
wherever in the world it is 24/7,” he said. “We certainly believe that this (IVHM) is one of the first truly comprehensive health management systems available for civil airplanes and certainly for business aircraft.” According to GE, by developing a comprehensive Web-based
aircraft health management service that provides high-fidelity interpretation of data, IVHM has made it possible for G650 (and surely other aircraft operators in the future), to monitor trends and detect and predict anomalies earlier and with greater confidence. Of course GE is not new to the health and management business. The roots of the IVHM technology date back to 1991, when GE developed the world’s first certified Health and Usage Monitoring System (HUMS) for helicopters.
“HUMS was developed to focus on the safety critical systems of a helicopter – primarily the dynamic components,” Baker
