ESSIP Plan 2014 / Objective ATC 02.2 2

Comprehensive Explanation (1/2)

Implementation of ground-based Short Term Conflict Alert (STCA) safety net

ECAC – wide applicable

Requires implementation by all ATC units that provide surveillance (= radar) services to General Air Traffic (GAT) within En-route airspace, in the Terminal Area (TMA) and or Control Zone (CTR).

For Military Authorities: Military ATC authorities are invited to consider implementation of STCA level 2 when providing ATS surveillance services to GAT.

Comprehensive Explanation (2/2)

STCA checks the extrapolated track positions based on radar data (current track position) and performs a linear extrapolation using the detected ground speed and predicts or establishes an actual conflict between a/c.

A conflict is declared if a/c tracks are separated less than the minimum separation thresholds.

Some Flight Plan (FP) data like Cleared Flight Level (CFL) can be used to suppress false alarms.

STCA requires appropriate presentation of predicted/actual conflicts to the tactical controllers and ATC supervisor.

Most important SLoA(s)

ASP01 “Implement STCA systems and associated procedures in line with EUROCONTROL Specification and related guidance material in En-Route airspace, applicable TMAs and Military ATC units providing radar services.”

ASP03 “Develop safety assessment for the changes, notably ATC systems and procedures that will implement STCA – level 2 functionality and associated procedures.”

ESSIP Plan 2014 / Objective ATC 02.26

Finalisation Criteria & Closed Questions

ASP01 – STCA function is implemented, documented and in operational use.

ASP03 – The Safety Assessment report including safety arguments for the changes has been delivered to the NSA and a notification of acceptance was received. STCA implemented at ACC level? STCA implemented in all TMAs / Towers within CTRs that provide radar

services? STCA parameters tuned to the operational environment (traffic,

suppression of alarm in pre-defined areas, look-ahead time, warning time)?

Safety assessment done and accepted by NSA? Notification of acceptance received from NSA?

10 States reported LATE.

Implementation delays / not achieved due to: implementation of a new ATC System Implementation and/or validation/verification of STCA before putting into

operation delayed Implementation of STCA in TMA area delayed

Need to implement STCA to avoid impact on safety and achievement of expected safety benefits
