STCA (Short Term Conflict Alert) is a ground-based system designed and deployed to act as a safety net against collisions. The system, which can be used in both en-route and terminal manoeuvring areas (TMAs), generates an alert to warn air traffic controllers for when separation minima between aircraft have been infringed upon. The system makes use of down-linked aircraft parameters (DAP) available through Mode S EnHanced Surveillance (EHS) (i.e. Selected Flight Level, Roll angle/Track angle rate) are to increase the reliability and accuracy of the alerts.
