Data is collected from different aircraft systems, sensor data and flight operation data. But it also comes from maintenance and pilot tech logs from maintenance information systems, pilot feedback, technicians, images and more. Data can even come from the supply chain. Clearly, these diverse systems contain different kinds of data (structured/unstructured) that need to be aggregated, merged and harmonized. This information is managed, analyzed and transformed into actionable knowledge and know-how to make better-informed decisions.
