The standard also describes the Centralized Fault Display System. ARINC is a family of standards covering "data loading", commonly used for transferring software and data to or from avionics devices. It provides a standard approach for quality management of Test Procedure Generation within the commercial air transport industry. It is installed on the Boeing

Each partition has to handle its own memory still under the constraints of memory partitioning enforced by ARINC However, there are differences between the two standards. POSIX defines the application programming interface API , along with command line shells and utility interfaces, for software compatibility with variants of Unix and other operating systems. QNX is a commercial Unix-like real-time operating system, aimed primarily at the embedded systems market.

QNX was one of the first commercially successful microkernel operating systems. As of , it is used in a variety of devices including cars and mobile phones. It is commonly implemented as a library of linkable modules. It originated with the 4. RTLinux is a hard realtime real-time operating system RTOS microkernel that runs the entire Linux operating system as a fully preemptive process. The hard real-time property makes it possible to control robots, data acquisition systems, manufacturing plants, and other time-sensitive instruments and machines from RTLinux applications.

Nucleus RTOS was first released in Aeronautical Radio, Incorporated ARINC , established in , was a major provider of transport communications and systems engineering solutions for eight industries: aviation, airports, defense, government, healthcare, networks, security, and transportation. ARINC had installed computer data networks in police cars and railroad cars and also maintains the standards for line-replaceable units.

The Linux kernel provides several interfaces to user-space applications that are used for different purposes and that have different properties by design. It pursues the objective to create and establish an open and standardized software architecture for automotive electronic control units ECUs. Goals include the scalability to different vehicle and platform variants, transferability of software, the consideration of availability and safety requirements, a collaboration between various partners, sustainable use of natural resources, and maintainability during the whole product lifecycle.

Avionics Full-Duplex Switched Ethernet AFDX is a data network, patented by international aircraft manufacturer Airbus, for safety-critical applications that utilizes dedicated bandwidth while providing deterministic quality of service QoS. AFDX is a worldwide registered trademark by Airbus. The six primary aspects of an AFDX data network include full duplex, redundancy, determinism, high speed performance, switched and profiled network.

ARINC technical standard for the predominant avionics data bus used on most higher-end commercial and transport aircraft. It is free open-source software. PikeOS is a commercial, hard real-time operating system RTOS that offers a separation kernel based hypervisor with multiple logical partition types for many other operating systems and applications.

It enables users to build certifiable smart devices for the Internet of things according to the high quality, safety and security standards of different industries. Integrated modular avionics IMA are real-time computer network airborne systems. This network consists of a number of computing modules capable of supporting numerous applications of differing criticality levels.

SYSGO GmbH is a German information technologies company that supplies operating systems and services for embedded systems with high safety and security-related requirements, using Linux. It provides a framework for describing open system concepts and defining a lexicon of terms, that can be agreed upon generally by all interested parties. The Application Interface Specification AIS is a collection of open specifications that define the application programming interfaces APIs for high-availability application computer software.

It is developed and published by the Service Availability Forum and made freely available. Besides reducing the complexity of high-availability applications and shortening development time, the specifications intended to ease the portability of applications between different middleware implementations and to admit third party developers to a field that was highly proprietary in the past.

An application programming interface API is an interface or communication protocol between different parts of a computer program intended to simplify the implementation and maintenance of software. An API may be for a web-based system, operating system, database system, computer hardware, or software library. An API specification can take many forms, but often includes specifications for routines, data structures, object classes, variables, or remote calls. Documentation for the API usually is provided to facilitate usage and implementation.

The Open Group Future Airborne Capability Environment was formed in 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. The FACE approach is a government-industry software standard and business strategy for acquisition of affordable software systems that promotes innovation and rapid integration of portable capabilities across programs.


Avionics Full-Duplex Switched Ethernet

In one abstraction, it is possible to visualise the VLs as an ARINC style network each with one source and one or more destinations. Virtual links are unidirectional logic paths from the source end-system to all of the destination end-systems. The virtual link ID is a bit unsigned integer value that follows a constant bit field. The switches are designed to route an incoming frame from one, and only one, end system to a predetermined set of end systems. There can be one or more receiving end systems connected within each virtual link. Each virtual link is allocated dedicated bandwidth [sum of all VL bandwidth allocation gap BAG rates x MTU ] with the total amount of bandwidth defined by the system integrator.
