On September 4-5, 2007 in Holiday Inn Warsaw, the last session of the CHAIN Implementation Workshop was held. The Polish Air Navigation Services Agency was a co-organizer of this meeting. The representatives of Sweden, Italy, Belgium, Turkey, Czech Republic, Great Britain, Egypt and other countries took part in the workshop. Among Polish delegates there were not only PANSA representatives, but also the Civil Aviation Office and the Polish Air Force’s Air Traffic Services officials. The meeting was inaugurated by Maciej Rodak, The President of Polish Air Navigation Services Agency. In his speech, he underlined the very important role of the aeronautical information and it’s influence on air traffic safety.
CHAIN Unit (Controlled and Harmonized Aeronautical Information Network) with Manfred Unterreiner (EUROCONTROL) as the Activity Manager, was brought into existence to prepare unitary European procedures managing aeronautical information flow, from their creation to the announcement in Aeronautical Information Publication. The reason is, that in the past, it happened that i.e. map coordinates of aerodrome’s reference point put into a geodetic register was changed during data processing.
CHAIN started its work form reading up the methods of aeronautical information management used by various European countries. Next, they were analyzed, and the conclusions were consulted with the experts. It is worth remembering that since 1995, and the crash of a liner Boeing 757 near Buga in Colombia, the aeronautical information is considered to be one of the CRITICAL safety elements of flights. That is why any changes of tested and verified source information during the process of preparing AIP are absolutely impermissible.
CHAIN conference in Warsaw was the last workshop, and the results of works of that unit are going to be presented on AIST Conference, which is taking place on September 26-28, 2007 in Brussels. The results and the changes which are to be implemented in aviation are convergent with ICAO Annex 15 requirements, the primary document regulating the flow of aeronautical information. CHAIN prepared the strictly specified diagram of the flow of such information, the methods of preparing and the pattern of the agreement (so-called SLA – Service Level Agreement), which should be signed by data providers (i.e. aerodrome management units) and the institution providing aeronautical information service. Some interesting software created for sending, verifying, authorizing and managing aeronautical information was also presented. In these programs, the biggest pressure was put on keeping source data unchanged during the whole procedure, and on clear, legible information processing stages.
Summing up the meeting, Mr. Manfred Unterriner considered Warsaw meeting very successful and expressed gratitude to the Polish Air Navigation Services Agency for arranging the session. The conclusions and projects, prepared by CHAIN are going to be send to Eurocontrol management, which will direct them for the consultations with the representatives of particular countries within AIST unit.
