Description
About the exercise
The trials validated procedures that make use of i4D capabilities to enhance queue management and minimise delays. Mainline aircraft were integrated into a simulator at Toulouse airport and connected with MUAC, while an Airbus 4D predictor validated trajectory exchange in en-route between air and ground. In addition, Malmö ATC Centre addressed the i4D+CTA concept in the TMA, using an extended Arrival Manager (AMAN) horizon to allocate a CTA on each arrival route.
Results
The exercises facilitated discussion on the concept between key stakeholders and helped identify issues for the next phase of concept development. The controllers who participated generally reported acceptance of the concept, with some caution expressed regarding the need for further refinement and assessment.
