CNS/ATM AVIONICS, FUNCTIONAL ALLOCATION AND RECOMMENDED ARCHITECTURES ARINC660A

This standard expands ARINC 660 to include industry-defined architectures for the CNS/ATM operating environment. These architectures are intended to meet long-term requirements (e.g., ADS-B, CPDLC, etc.) and provide growth for the future. Airlines support the implementation of these architectures for the long-term. This standard represents broad airline consensus for developing avionics equipment providing CNS/ATM operating capabilities.
