Avionics software is embedded software with legally mandated safety and reliability concerns used in avionics.The main difference between avionic software and conventional embedded software is that the development process is required by law and is optimized for safety.
Processes are intended to support the objectives, according to the software level (A through D—Level E was outside the purview of DO-178B). Processes are described as abstract areas of work in DO-178B, and it is up to the planners of a real project to define and document the specifics of how a process will be carried out.
DO-330 "Software Tool Qualification Considerations", a new "domain independent, external document", was developed to provide guidance for an acceptable tool qualification process. While DO-178B was used as the basis of the development of this new document, the text was adapted to be directly and separately applicable to tool development and ...
The Open Group Future Airborne Capability Environment (FACE Consortium) was formed in 2010 to define an open avionics environment for all military airborne platform types. Today, it is a real-time software-focused professional group made up of industry suppliers, customers, academia, and users.
ARINC 653 (Avionics Application Software Standard Interface) is a software specification for space and time partitioning in safety-critical avionics real-time operating systems (RTOS). It allows the hosting of multiple applications of different software levels on the same hardware in the context of an Integrated Modular Avionics architecture.
IMA modularity simplifies the development process of avionics software: . As the structure of the modules network is unified, it is mandatory to use a common API to access the hardware and network resources, thus simplifying the hardware and software integration.
The DO-254/ED-80 standard is the counterpart to the well-established software standard RTCA DO-178C/EUROCAE ED-12C. With DO-254/ED-80, the certification authorities have indicated that avionics equipment contains both hardware and software, and each is critical to safe operation of aircraft .
