Accelerating User Application Development
Developing software to drive A661 User Interfaces has just got easier with the UA2 tool. UA2 works exclusively with Presagis VAPS XT ARINC 661 capability to enable system and software engineers create User Applications HMI interaction quickly, consistently and accurately, without requiring extensive knowledge of the A661 protocols.
UA2 enables HMI graphics interaction to be defined in terms of behaviours driven by data; complex visual concepts can be designed and tested with real-time data in short time frames. Any changes to the user interface can be rapidly applied and demonstrated working with dynamic behaviour.
UA2 enforces a neat and logical split between system components and the user interface, by providing unit testable behavioural modules. The User Interface testing burden is reduced as is the impact of late requirement changes on core certified code.

Behaviour Based Design
UA2 allows engineers to map system entities onto widget behaviours assigned to widget instances.
- Complex widget behaviour is achievable with minimal knowledge of A661
- Engineers can focus on system requirements and behaviour
- Traceability and Documentation between the User Interface and System components
- Rapid Prototyping and Production Code Supported.
