What is i4D?
4D Latitude, Longitude, Altitude + Time
Sharing and synchronising airborne and ground trajectory.
Flying to a single time constraint
CTA at
Constraint Point
A first step towards 4D Trajectory Datalink (4D-TRAD)
What benefits do we expect from i4D?
Sharing and Synchronising Air & Ground Trajectories
Improved predictability
Better consistency of Air and Ground Trajectories
Enhanced automation between air and ground
Enhanced Conflict Detection and Resolution
3
Flying to a time constraint when traffic requires it
More strategic management of arrival flows, less tactical interventions
Improved flight efficiency through optimised speed and descent profiles

How we are validating i4D?
A combination of validation techniques
Fast Time Simulations and modelling
Local Real-time simulations
Coupled Real-Time Simulations, connected with Airbus Cockpit simulator
Flight trials with A320 Test aircraft
Validations address a variety of operational contexts
including mixed equipage scenarios

What you will see in the first demonstration
• A 7-minute film
– Selected portions of a simulated flight cruising through Maastricht UAC then descending to CPH
– Recorded during rehearsal sessions to prepare the i4D flight trial planned on 19th March
– Illustrates:
• Exchange of 4D trajectory
• Use of CTA to sequence arrival traffic
– 3 screens each showing a particular angle of i4D operations:
