In this third issue of the Presagis Embedded Graphics Newsletter, learn how Presagis strives to simplify the development cycle for customers by developing tools with industry standards in mind. Presagis provides products and expert services for the development of ARINC 661 compliant applications. Read on to discover useful information and resources to help you better understand the ARINC 661 standard. This issue shines the spotlight on the partnership between Presagis and Flexible Software Solutions. Specifically, the power of Flexible Software Solutions' User Applications Accelerator (UA2), which works exclusively with the VAPS XT 661 module to link User Applications to the HMI quickly, consistently, and accurately, without requiring extensive knowledge of the ARINC 661 protocols. |

ARINC 661 \ THE STANDARD ARINC 661 is a standard which aims to normalize the definition of a Cockpit Display System (CDS), and its communication with the User Applications (UA) which manage Aircraft avionics or tactical functions, such as those in Flight Management Systems, Mission Systems, and Aircraft Alerting Systems. The first version of the standard was adopted in 2001 and, over the last decade, has evolved to a fourth supplement that was published in 2010. The objective of the ARINC 661 is to minimize both direct and indirect costs to the airlines by:
Recent major commercial programs have adopted the standard, including Airbus on the A380 and A400M, Boeing on the 787, and AgustaWestland on the Merlin Mk2. Assessing industry trends, Presagis develops its products with standards, such as ARINC 661, in mind. To complement its next-generation HMI development tool, VAPS XT-178, Presagis developed a fully integrated add-on module that allows a seamless transition to ARINC 661 compliance for embedded systems projects. The VAPS XT 661 module is a simple way for customers to align their projects with the ARINC 661 standard.

ARTICLE \ UNDERSTANDING ARINC 661 AND ITS BENEFITS IN A CERTIFIED ENVIRONMENT
This lack of a standards-based approach led to the proliferation of monolithic applications, either developed internally or through the use of commercial tools. These applications always need to be recertified as a whole, no matter which type of change is made. Exchanging data between commercial tools is also usually difficult, making it a challenge for aircraft manufacturers 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. In the late ’90s, a committee of representatives from the industry was formed to address these concerns and put together a standard and flexible architecture for the creation of aircraft avionics which became ARINC Specification 661: Cockpit Display System Interfaces to User Systems. Today, ARINC 661 is used on programs such as the Airbus A380 and A400M, the Boeing 787 and the AgustaWestland Merlin Helicopter Upgrade. This standard has been used in the military realm since its inception, with its most recent iteration published earlier this year. PARTNER SPOTLIGHT \ FLEXIBLE SOFTWARE SOLUTIONS
What does Flexible Software Solutions do? Flexible Software Solutions provide software process improvement consultancy, HMI best practice advice, ARINC 661 widget definition, and User-Application development support. Our UA2 development tool accelerates and de-risks user application development by combining the advantages of the VAPS XT 661 module, and behavioral definition based approaches. How are customers benefiting today from the FSS / Presagis partnership? Customers are halving their User Interface and User Application specification time and optimizing deployed HMI production, by combining the power of Presagis VAPS XT HMI Display Graphics software with Flexible Software Solutions VAPS XT to modelling tool integration. Previously laborious responsibilities such as “consistency enforcing” and “DO-178B testing documentation” are greatly simplified freeing up system and software engineers to focus on value adding tasks. The UA2 rapid prototyping and demonstration environment is backed up by through-project support helping VAPS XT customers deliver feature rich User Interfaces integrated with system components efficiently. Can you explain how User Application (UA) development is accelerated with UA2? UA2 works exclusively with Presagis VAPS XT ARINC 661 capability to enable system and software engineers to link User Applications to the HMI quickly, consistently and accurately, without requiring extensive knowledge of the ARINC 661 protocols. UA2 enables HMI interaction to be defined in terms of behaviors driven by data; complex visual concepts can be designed and seen working in short time frames. Additionally, changes to the user interface can be rapidly applied and demonstrated working with dynamic behavior. UA2 enforces a neat and logical split between system components and the user interface, by providing unit testable behavioral modules. The User Interface testing burden is reduced as is the impact of late requirement changes on core certified code. UA2 allows engineers to map system entities onto widget behaviors assigned to widget instances.
