The Site Acceptance Test is a milestone in Finavia's migration to the ATS Message Handling System (AMHS) as mandated by ICAO.
Finavia has been operating the Frequentis AFTN/CIDIN Message Switch and OPMET systems since 1999.
The new systems, installed at Helsinki-Vantaa International Airport, include Frequentis MessageServer and the OPMET system.
MessageServer is configured to support the AFTN, CIDIN and AMHS (X.400) message formats in full compliance with the ICAO AMHS Euro Manual and Eurocontrol AMHS Specifications.
The OPMET system is configured to receive data from SADIS 2G and produces Wind and Temperature and Significant Weather charts from GRIB and BUFR data.
The system also produces WMO formatted bulletins and responses to Winds Aloft queries.
The systems were implemented in full compliance with the EC safety and interoperability regulations.
Prior to the installation in Finland, MessageServer had successfully passed AMHS conformance and interoperability tests.
The interoperability tests were conducted with the DFS AMHS system installed in Langen, Germany.
The results of the tests were published during the AFSG/12 meeting.
