The tool has comprehensive detection and de-confliction functionalities based on aircraft ‘city pair’ and airspace volume data stored by the Network Manager.
A stepped approach is being taken to organise access to the tool:
The Network Manager has put in place a 'service level 0' to provide the aircraft operators with the similarity rules to be applied in the process of the detection and resolution of conflicts.
- Service level 1 operations focus on the detection and deconfliction of call sign similarities with a single aircraft operator’s schedule using the CSS tool.
- If Service level 1 is successful, service level 2 will provide de-confliction between multiple aircraft operator schedules.
- Service level 0 is public whereas service level 1 and 2 are available upon subscription and signing of a service agreement, and allow access to the CSS Tool.
EUROCONTROL established procedures with participating aircraft operators to monitor the CSST’s operational effectiveness. In particular, we are monitoring the anticipated improvements in safety performance in conjunction with the EUROCONTROL voluntary ATM incident reporting (EVAIR) scheme.
EVAIR records show that for those aircraft operators who use the CSST to de-conflict their own schedules there have been very few, if any, reported similarity and confusion events. Comparisons with their pre-CSST performance demonstrate that the CSST definitely helps reduce operational risk and improves flight safety.
