GUIDANCE FOR DISTRIBUTED RADIO ARCHITECTURES ARINC678

The purpose of this document is to evaluate Communication, Navigation, and Surveillance (CNS) Distributed Radio architectures and the feasibility of distributing the RF and systems processing sections to ensure the following:

• Reduce cost of equipment
• Reduce Size, Weight, and Power (SWaP)
• Ease of aircraft integration
• Growth capability built into the design
• Maintain or improve system availability, reliability, and maintainability

It provides a framework to determine whether it is feasible to develop ARINC Standards that support CNS distributed radio architectures.
