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.

Rick Hearn explains how the key computing elements of an avionics system must all be designed with safety in mind and endure stringent testing to prove they can meet the required Design Assurance Level (DAL).

Given its complexity and the critical applications for which it is designed, embedded avionics software must undergo a rigorous approval and testing process before it can be approved as airworthy.

The rise of the Internet of Things (IoT) and Industrial IoT (IIoT) is not the only reason for increased demand for safety- and security-related solutions.

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.
