The increasing digitisation of aircraft operations and support in recent years have made it possible to monitor, assess, and predict the health of aircraft structures, systems, and components more often. Different activities fed into what is called condition-based maintenance (CBM) strategy, is believed to offer significant benefits in terms of both cost and time. These activities are typically summarised using terms like predictive maintenance, prognostics and health management (PHM), integrated vehicle health management (IVHM), or aircraft health management (AHM).
