Abstract. In this paper are analyses the types and development principles of aircraft air/ground
communication architecture, which is used for acquiring, conditioning and processing all required aircraft
parameters, collected from the aircraft and data, receives on low and high speed ARINC 429 buses. The paper also considers the possibility of receiving and sending data via ARINC 618 buses.
On the example of modern aircraft such as the Boeing 777 and Boeing 787, the functionality of
air/ground communication, built on the basis of a data communication management system (DCMS) and the rinciples of modernizing the airborne radio communication system, are investigated.
This paper also explores the capabilities of the Data Communications Management System (DCMS)
system architecture and interfaces for interfacing with other existing aircraft systems to send reports/queries on the uplink or downlink.
Keywords: Aircraft, datalink, communication, interface, uplink request, downlink request.
