About this exercise

The live trial procedures were implemented in Paris ACC, and tested the requirements and cases for using point merge in an extended TMA with the aim of achieving CDA from high altitudes in high traffic.

Results

• An increase in safety resulting from a more structured airspace
• A reduction in the controller workload, due to the reduction in frequency usage, that could allow an increase in capacity;
• An improvement in trajectory prediction and a reduction in the number of open loops which will have a positive impact on predictability;
• The simulation exercises showed no increase in fuel burn for arrivals.
