The ARINC avionics display standard has been in existence and evolving for close to a decade – with its most recent iteration published. Find the most up-to-date version of ARINC at Engineering ARINC is a standard for commercial aircraft cockpit displays, and VAPS XT from Presagis allows embedded avionics display designers and developers to.

Beyond isolation benefits, this approach also simplifies the distribution of application development between different teams within an organization or across subcontractors. This solution allows the user to: While the implementation of this architecture might seem a bit daunting — considering aarinc need to put in place a compliant CDS runtime software architecture, a functional widget library that adheres to the specification, and tools to facilitate the creation of Definition Files and their output to standard binary files — it should be noted that COTS tools are available to provide these capabilities out of the box.
Through new display modeling technology, VAPS XT offers unprecedented flexibility and time savings for creating user-defined objects and displays. This solution allows the user to:. He can be reached at yannick.
Naturally, a display system would not be much without its associated logic which is handled by a separate element called the User Application UA. Presagis technical services can help you accomplish the following tasks:.

The approach used allows the modeled design to be shared across different teams in order to obtain feedback from all stakeholders and maintain design consistency. There is also a provision in the standard to allow developers to create custom widgets with tailored functionality and parameters that still follow general widget creation patterns. This number went up to 50 with the first update to the standard, standatd 57 with supplement 2, to 65 in revision 3 and to 68 with its most recent incarnation published earlier this year.
To make things even more complicated, many players in the industry use their own development methodologies with little to no guidelines on content other than the instructions of their developers and human factors engineers.
In addition, any Presagis software application can leverage user plugins and can integrate with other third party products. Figure 1 shows the relation between the CDS and UA, along with their typical execution environments and the communications between these two applications. This page was standaard edited on 26 Novemberat The ARINC Specification defines an overall architecture along with many sub-components to facilitate the creation of interactive displays.
Standards Tsandard are at the core of interoperability and reusability. Archived from the original PDF on An example in this last category is the MutuallyExclusiveContainer widget that groups multiple elements under a single parent but only displays one of its immediate children at a time. While ARINC describes how widgets should function and what their parameters are, it does not define their visual appearance.
The natural follow-on step is the ability to convert the XML definition files to the binary format that is required by the CDS for execution. Archived from the original on 11 June Managing risk with automatic code generation, standards, and simulation”.

Automatic Code Generation ensures that any changes needed can be implemented and re-tested in the shortest amount of time possible, without having to hand-code every time.
Furthermore, ARINC defines the CDS as a runtime interpreter capable of displaying one or more elements from a finite library of building blocks called widgets based on information contained in external layout files.

UA Accelerator is designed to augment your existing modeling tool-sets and software development processes. ARINC is a standard for commercial aircraft cockpit displays, and VAPS XT from Presagis allows embedded avionics display designers and developers to easily and cost-effectively meet this emerging avionics standard.
They are natively stored in a binary format that is loaded into the CDS application at stabdard. Exchanging data between commercial tools is also usually difficult, making it a challenge for aircraft aeinc to think about switching providers for a system during the life cycle of an aircraft — or to reuse display elements between projects that are built using different software architectures. Cockpit Display System CDS and User Application UA A direct benefit of this architecture is that updates to the display composition are done by creating new layout files instead of modifying code within a unified application.

The widget library is similar to Widgets used in computing. With VAPS XT Module, you can define the graphical representation and behavior of widgets according to the look and feel specified by the Style Guide of any given aircraft manufacturer. The same benefit applies to changes to the logic flow of the application, which will only result in changes to a specific user application, leaving the CDS code base and other user applications unaffected.
In the latter case, an event is sent to the appropriate UA to determine a response based on the current system state and the event type. In order to be compliant with the standard, a CDS must have a kernel that can create the widgets tree during CDS initialization, using the Definition File, and communicate with UA in both ways using the runtime protocol.
While cockpit display software has traditionally been written as self-contained executables that present information and render graphics based on internal data, rules, and logic, ARINC introduces a clear separation between the code drawing the graphics and the code managing the logic and the position and state of all visual elements. When it comes to certification, this detailed display architecture greatly simplifies the creation of high- and low-level requirements.
There are also some widgets that do not have any visual representation that are used to group other elements together as well as apply transformations on them.
