ARINC 661 is a standard which aims to normalize the definition of a Cockpit Display System (CDS), and the communication between the CDS and User Applications (UA) which manage aircraft avionics functions. The GUI definition is completely defined in binary Definition Files (DF). The CDS software is constituted of a kernel which is able to create the GUI hierarchy specified in the DF during initialization, thus not needing to be recompiled if the GUI definition changes. The first version of the standard was adopted in 2001. Its first use was for Airbus A380 CDS development.The first supplement was adopted in 2003, and added new widgets.The second supplement was adopted in June 2005, and added supplementary widgets. Third supplement has been adopted in 2007. Supplement 4 was adopted in 2010. The standard is known today to be used for Airbus A380 and A400M CDS development, and also Boeing 787 CDS development. AgustaWestland company use ARINC 661 for the development of a new Touchscreen unit in the upgraded Merlin helicopter for the Royal Navy. In March 2011, Embraer announced that it selected SCADE Solutions for ARINC 661, a COTS (Commercial Off The Shelf) tool for ARINC 661 development, for its future developments. An ARINC 661 Part 2 is currently in development, allowing to define custom widgets.
