Develop ARINC 661 compliant, interactive, real-time graphical embedded HMI displays
Standards compliancy continues to be a concern for mission and safety-critical programs, reinforcing the need for reliable, high quality code. The stringent requirements of DO-178B/C, a need for applications that interoperate with DO-254 compatible hardware and an increased desire for ARINC 661 compliancy can all lead to higher system complexity and the need for extensive testing which risks project delivery overruns and unforeseen expenditures.
The ARINC 661 Specification defines an overall architecture along with many sub-components to facilitate the creation of interactive displays.
The first of these components is the Cockpit Display System (CDS), a rendering engine dedicated to presenting graphical information. Naturally, a display system would not be much without its associated logic which is handled by a separate element called the User Application (UA). The link between these two pillars is the ARINC 661 Runtime Protocol, which carries events that are generated through user interaction to the UA and brings requests to display new data back o the CDS. Finally, the contents of the displays, from graphical elements to possible groupings of these components, are defined by using a finite set of components called the widget library.
Presagis ARINC 661 Development Suite is an integrated, end-to-end workflow environment for the entire lifecycle of ARINC 661 systems development: from requirements specification, design, and development through deployment and maintenance. The Suite provides a seamless workflow between development environments for the Cockpit Display System (CDS) and the User Application (UA) so you can create certifiable systems faster and more easily.
With the complete Presagis ARINC 661 Development Suite, an end-to-end runtime environment can be deployed both in a simulation and test environment in development labs and in embedded systems aboard aircraft.
ARINC 661 CDS Development Suite
The CDS Development Suite comprises the original VAPS XT 661 Module and the UA Emulator tool, which enables you to test and validate the CDS system independently of the UA application. Save valuable debugging time by being able to fully test and validate your CDS system before connecting to the UA system.
The ARINC 661 CDS Development Suite includes:
- VAPS XT 661
- User Application Emulator (UAM)
For developing cockpit display systems, Presagis offers VAPS XT, a model-based development tool that includes automatic code generation functionality. 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. 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.
For projects requiring ARINC 661 compliancy, customers can implement the VAPS XT 661 Module. Introduced in 2004, this module allows for the rapid implementation of ARINC 661 compliant graphics. It provides a quick and easy way to specify and design any cockpit display system that requires compliance with the new ARINC 661 aviation standard. With VAPS XT 661 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.
Teams of HMI developers use VAPS XT 661 Module to jointly develop the look and feel of avionic subsystems and Cockpit Display Systems with User Applications. Through new display modeling technology, VAPS XT 661 offers unprecedented flexibility and time savings for creating user-defined objects and displays.
VAPS XT 661 Module offers the following functionality:
- incredible flexibility and extensibility for developing user-defined objects/widgets,
- an easy-to-use graphical editor that speeds up ARINC 661 display design,
- powerful Object Model based architecture,
- display layout files that are saved in an extensible human-readable XML format,
- A vast amount of out-of-the box ARINC 661 widgets
Presagis' flagship product VAPS XT is the ideal solution for projects involving ARINC 661 compliance, and we are committed to providing software that allows embedded avionics display designers and developers to easily and cost-effectively meet this emerging avionics standard.
ARINC 661 is a very specialized field in HMI development. If you are new to the standard, Presagis ARINC 661 experts can help you develop your displays in conformance with the ARINC 661 standard. Presagis technical services can help you accomplish the following tasks:
- Define ARINC 661 widgets
- Create extended widgets based on the ARINC 661 standard
- Build your own ARINC 661 widget library with your own look and feel
- Layout ARINC 661 widgets to create HMI applications to be used by the Cockpit Display System (CDS)
- Develop and optimize the Cockpit Display System (CDS) and User Application (UA)
- To implement the data connection between input and output objects
