A320 Undertakes Second I4D Trial

Airbus’ A320 ‘MSN001’ flight-test aircraft has undertaken the second ‘initial 4D’ (i4D) trajectory flight trial as part of a joint project with its members in the EU-funded Single European Sky ATM Research (SESAR) Joint Undertaking (SJU). These members are: Thales, NORACON, Maastricht Upper Area Control Centre (MUAC), Indra, Eurocontrol, Honeywell and Airbus. The first flight trials took place in 2012. The i4D flights provide a reduction in fuel burn and C02 emissions; the second flight trial validated further that “the sharing of trajectory information between the air and ground can enable a safer and more efficient handling and certainty of flight profiles”, according to Airbus.
