UA² - COTS User Application Development Tool

User Application Accelerator (AKA UA Squared) logo, Trade Mark Protected.

There are many pitfalls when developing systems that interact with ARINC 661 displays. Problems are seldom trivial and can quickly lead to complex and costly bespoke solutions where system features become compromised. UA Squared is a development tool targeted specifically at the interaction between systems and ARINC 661 displays, accelerating development, reducing costs and technical risk.


Tool Mission:

Provide an environment that enables the development of a system’s interaction with ARINC 661 displays to be developed quickly, consistently and accurately, maximising the use of existing core system software development process and tools.


Features for Software Developers:

  • Import / Synchronisation of CDS Layer and Widget Designs – tie system code to widget representations, removing the need to maintain knowledge of widget identifiers,

  • Build re-usable components for display control, without writing any code,

  • Use widget behaviour definitions to quickly control interaction with an ARINC 661 display,

  • Integrates into your preferred software development tool – accelerating development time,

  • Code Generation – fewer errors, reduced certification time.

Features for Human Factors Experts:

  • Provides reusable format conversion and widget behaviour specifications – helps to enforce user interface consistency, simplifies the development of a “Style-Guide”,

  • Features for Simulation / Research and Development Teams,

  • Rapid prototyping is possible, with minimal ARINC 661 expertise,

  • Make and see effect of design changes quickly, without editing code,

  • Drive the CDS with test harness and “real world” system data, show dynamic behaviour without reliance on the real equipment.

Features for Program Management:

  • Accelerates the development of User Applications,

  • Simplifies supporting multiple display targets with a common core-system,

  • Reduced reliance on ARINC 661 expertise,

  • De-risk user interfaces quickly, simplifies the sharing of ideas and process across teams,

  • Simplifies system integration activities, especially for projects with distributed development teams,

  • Integrates into existing core-system development tools and process.
