The company was founded by Robert S. Randazzo, who stated that his ultimate goal was to develop the software to the point where it could be used ...
The main difference between avionic software and conventional embedded software is that the development process is required by law and is optimized for safety. It is claimed that the process described below is only slightly slower and more costly (perhaps 15 percent) than the normal ad hoc processes used for commercial software .
The Software Level, also known as the Development Assurance Level (DAL) or Item Development Assurance Level (IDAL) as defined in ARP4754 (DO-178C only mentions IDAL as synonymous with Software Level [10]), is determined from the safety assessment process and hazard analysis by examining the effects of a failure condition in the system. The ...

Aircraft that regularly operate in icing conditions have systems to detect and prevent ice forming (anti-icing) and/or remove the ice accumulation after it has formed (de-icing). This can be achieved by heating the spaces in internal structure with engine bleed air, chemical treatment, electrical heating and expansion/contraction of the skin ...
As modules often share an extensive part of their hardware and lower-level software architecture, maintenance of the modules is easier than with previous specific architectures. Applications can be reconfigured on spare modules if the primary module that supports them is detected faulty during operations, increasing the overall availability of ...
