Analysis Of Mixed Critical Avionics And Systems

A goal of next generation avionics systems is the integration of avionics and mission applications on shared resources to reduce their size/weight/power requirements and enable increased range, additional payload capacity, and reduced logistics footprint and costs. The integration complexities can increase costs especially if mixedcriticality applications (e.g., safety-critical, mission-critical, non-critical) are hosted on the same resource since every application, regardless of criticality, must be certified (tested) to the level required by the highest criticality application hosted on the resource. This adds significant cost to fielding complex systems, e.g. helicopter avionics and Unmanned Autonomous Systems (UAS) that must integrate mixed-critical capabilities while mindful of size, weight and power concerns (SWaP). In this environment, the ability to provide mixed-critical attributes, such as security, real-time fault tolerance and performance is critical for predictable system response.
