Ensuring that European voice is heard on ACAS standardisation and validation processes

6 December 2017

EUROCONTROL has recently hosted the fourth meeting of the Project Management Board of the Agency-lead SESAR 2020 Collision Avoidance Performance Improvement Technology (CAPITO) project (PJ11). The meeting brought together project participants from the SESAR Joint Undertaking, DSNA, Thales, Honeywell, Dassault, Leonardo, INDRA and EUROCONTROL to discuss the road towards more coherent ground-based and airborne safety nets.

When it comes to the evolution of standardisation and validation processes, it is essential that European airspace operations are represented, especially with regard to the evolution and impact of SESAR initiatives on the design of safety nets.

The CAPITO project studies the impact of new separation modes and categories of airspace users on safety nets in order to help the evolution and improve the integration of technologies such as the Short Term Conflict Alert (STCA) and the Airborne Collision Avoidance Systems (ACAS). This helps to ensure that global initiatives are aware of and can benefit from efforts made at a European level like the evolution of SESAR’s trajectory management and new separation modes are represented. The scope of work is extended from that performed within SESAR1 to include remotely piloted aircraft systems (RPAS), general aviation, rotorcraft and military operations.

Ground-based and airborne safety nets in place today fit performance requirements based on current models of separation. Thus, their evolution is necessary to abide to the future operations identified by the SESAR programme. The CAPITO project aims to adapt ACAS and STCA operations to SESAR trajectory management and new separation modes.
