AIDC Interaction between Magadan ACC and Anchorage ARTCC

AIDCHistorical Background, Current State of Things

According to the intentions announced by FSUE “State ATM Corporation” atCPWG/13 meeting the branch “North East Air Navigation” has arranged workon the voiceless interaction between Magadan ACC and Anchorage ARTCC onAIDC protocol: The equipment project developed in 2017; The hardware facilities for AIDC messaging delivered, installed, adjusted and

started up; The automated Alpha system software updated; The software and equipment bed tests run locally; The local tests of the automated ATC system “Alpha” carried out at ATC

working places in online mode.

AIDCHistorical Background, Current State of Things

The Memorandum of Understanding for operational testing between Magadan ACCand Anchorage ARTCC signed.

In accordance with the MOU we have been conducting the operational testing since July 26, 2018.

The draft LOA between Magadan ACC and Anchorage ARTCC which provides for thecoordination procedures on AIDC protocol is prepared and agreed upon.

The normal mode of operation of the voiceless interaction between Magadan ACC and Anchorage ARTCC on AIDC protocol is planned to be started in September 2019.

The message exchange results as of May 01, 2019 are the following:Anchorage → Magadan – 98,06%Magadan → Anchorage – 98,56 %

Implementation Plan

In the course of the operational testing we are identifying thepossible errors and are eliminating their causes. The software is quicklymodified in Magadan ACC when necessary. These measures havealready helped decrease significantly the number of errors during theAIDC coordination.

In fact the operational testing of the voiceless AIDC interaction hasalready allowed to reduce the air traffic coordination workload for ATC.The AIDC implementation will allow enhancing the airspace capacity ofthe Magadan ACC sectors.

THANK YOU FOR YOUR ATTENTION!
