Avionics Systems Cost Increasing
35-40%*
Of a Civil aircraft costs are
attributed to the
Avionics Systems

Manufacturers Under Increasing Pressure
$
LIFECYCLE COSTS
 More functionality being
added to the cockpit
 Development timescales
being reduced
 Increasing level of competition
 Hardware obsolescence driving
up lifecycle costs
rights reserved.

A Standard For Systems Development
ARINC 661 – Defines a standard method for multiple avionics
systems to interact with a display
Key Objectives:
 Minimize costs of adding new display capabilities
 Reduce the amount of Re-certification required for changes
 Minimize costs of hardware obsolescence management
 Increased interactivity in the cockpit
 Standard way to add interactivity in the cockpit

VAPS XT-178 User Certification Process (i)
> Planning
> VAPS XT-178 PSAC should be referenced from user PSAC
• The VAPS XT-178 PSAC covers tool qualification and certifiable
components
• Liaison with Cert Authority should include acceptance of the usage of
VAPS XT-178
> User’s development process for a VAPS XT-178 application can
take advantage of model based design and verification
• Should be addressed in user’s plans and standards
rights reserved.

VAPS XT-178 User Certification Process (ii)
> Model Development and Verification
> VAPS XT-178 model is the Design/LLRs for the user’s application (HMI
application or A661 widget library)
• User activities are focused at the functional and model levels rather than down
at the source code level
> User Certification activities:
• Develop and verify model against System/High Level Requirements
• Test model against System/High Level Requirements:
– Model coverage analysis should ensure design and low level requirements testing is
complete
– Structural coverage of generated code is facilitated by VAPS XT-178 generated code
design
» Includes links back to model elements)
– User testing should also achieve integration with target computer

• User coded objects are developed in the same way that Presagis
develops the standard objects
• Develop coded objects against user requirements and VAPS XT-178
design and standards
• Verify user coded objects
