The Government of Greece decided to build a new airport in Athens to increase the capacity of air transportation and to be fully prepared for the Olympic Games in 2004. The new Athens International Airport called Eleftherios Venizelos located in the area of Spata Attica commenced operation in March 2001. HCAA asked EUROCONTROL to test new TMA procedures for Eleftherios Venizelos airport, to develop and test new SIDs and STARs and to ascertain any potential problems by carrying out realtime and fast time simulations. In this context, Spata 2000 Real-Time Simulation took place at the EUROCONTROL Experimental Centre. During the simulation controllers participated in 53 simulation exercises in a total of 73 simulation hours.
