Historically, the majority of avionics display manufacturers have sought custom solutions to support the development of cockpit displays, head-up displays and other avionics on-board and ground displays, from specification through to target. This was however a decision borne out necessity rather than choice since the inherent wisdom of a ‘commercial-off-the-shelf’ (COTS) approach had been understood and demonstrated in other parallel domains for some time. So, with this in mind, why was a more costly custom approach selected?

The ARINC 661 standard [1] 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.
