The ARINC 661 standard  defines a Cockpit Display System (CDS) interface intended for all types of aircrafts installations. This paper presents an integrated solution based on Commercial Off-The-Shelf (COTS) tools that allows, in the initial stage of an aircraft project, support for the expression of requirements with regards to the CDS definition and the CDS interaction with the User Applications (UAs). It also enables prototyping of the systems architecture from the point of view of functionalities and performance. At a later stage of the project, this same integrated tool suite can be used to produce and certify the final embedded software code within the CDS and to generate the communication code between the CDS and the UAs. As a conclusion, the paper demonstrates that the proposed solution, configurable and relying on model-based design and qualified automatic code generation of graphics, logics and communication code for both the Server and the User Applications, provides costs and time benefits. It significantly decreases the overall software development and modifications costs. It decreases the time-to-certification, and it is an important step in allowing for more modular certification of the aircraft components.
