It can be laborious and time-consuming to troubleshoot and repair systems on aircraft. Without granular data, it can be difficult for maintenance personnel to identify what part of a system is faulty and it can take a long time to remove, test, and reinstall parts of a system until the culprit is found.

Aircraft data acquisition technology continues to evolve with more modularity, increased processing power and real time air-to-ground transfer capabilities alongside increasing proliferation of engine, aircraft system and airframe component sensors.
