Short-term conflict alerts (STCA) provide controllers with a short-term warning of potential conflicts between aircraft in the same airspace. Enhancing the STCA safety net with information down-linked from the aircraft provides more accurate data on which to base warning signals.

This solution is implemented by eight ANSPs (Austria, Germany Denmark, Ireland, Moldova, Malta, Maastricht Upper Area Control Centre and Poland) and planned by five ANSPs (Armenia, Spain, France, Lithuania and Portugal).
