ARINC660C 660C CNS/ATM Avionics Architectures Supporting NextGen/SESAR Concepts

The origin of this ARINC 660C is traced to a number of industry activities but focuses primarily on the evolving airspace operations to be implemented by NextGen and SESAR that appear feasible in the next decade. From these inputs, the AEEC defined impacts on avionics architectures that would apply to in-production and in-service airplanes, recognizing that the impacts on the architectures would vary as a function of the existing avionics baseline. The equipage impacts described in ARINC Report 660C are intended to provide the airlines with the necessary information to evaluate modernization proposals and to support the overall goal of fleet commonality while meeting operational requirements.
