Second i4D test flight crosses MUAC airspace successfully

19 March 2014

Air travel will become even more predictable in the future thanks to the work undertaken within the SESAR Programme to develop and validate initial 4D (i4D) trajectory management – connecting aircraft and ground systems to optimise the aircraft trajectory in three dimensions plus time.

Prepared by SESAR members Airbus, EUROCONTROL, Honeywell, Indra, NORACON and Thales, a flight trial from Toulouse to Copenhagen and then Stockholm, successfully validated the sharing of trajectory information both in ground and airborne operations, and the capability of the aircraft to comply with time constraints in the en-route and approach phases of the flight.

The flight trial further confirmed that i4D offers important safety and environmental gains, as well as increased flight predictability and overall network efficiency.
