Thomson-CSF SA says its Syseca unit won a contract worth several million dollars to provide a turnkey system to send messages between 29 European civil aviation agencies: the contract, awarded by Eurocontrol, which oversees air traffic control across Europe, calls for installing the system by end-1993, and the contract is part of a vast programme to link up Europe’s air traffic control systems – the present fragmentation is one of the key causes of the air travel delays; the Central Flow Management Unit system will be based on Syseca’s Aermac product, and will collect flight plans from the World Civil Aviation Network, the SITA airline network SITA and from air traffic control centres; it will be installed at two central sites, at Haren, Belgium and Bretigny-sur-Orge, France, using Stratus Computer Inc fault-tolerant systems connected via an X25 packet-switched network.
