Objective ATC 02.6 ESSIP Plan 2013 Ingrid FEIJT DSS/EIPR

ESSIP Plan 2013 / Objective ATC Comprehensive Explanation (1/2) Implementation of Minimum Safe Altitude Warning (MSAW) function. ECAC applicability (except Greece and United Kingdom). Requires implementation by all ATC units providing radar services to GAT traffic within En-route airspace, TMAs and CTRs. Military applicability: Military ANSPs that provide radar service to GAT traffic.

Comprehensive Explanation (2/2) MSAW checks the extrapolated track positions (based on radar data = current track position and linear extrapolation using ground speed) and identifies the predicted or actual conflicts against the terrain. Terrain can be build up using digital terrain data or set of polygons that sufficiently accurate shape the vertical environment. Conflict is declared if a/c track is below the minimum safe altitude (usually 500 to 700 feet above the terrain) intends to do so in short distance in time (<= 2 minutes). Some FP data like Cleared Flight Level (CFL) might be used to suppress false alarms. MSAW requires an appropriate presentation of predicted / actual conflicts to the tactical controllers and ATC supervisor. MSAW requires careful optimisation / tuning to minimise false alarms.

Most important SLoA(s) ASP01 Implement the MSAW function. Put into service ground- based safety tool systems and associated procedures supporting the MSAW function. ASP to check the compliance of the implemented MSAW with the requirements stated in the specification, the related guidance material and the relevant training and safety requirements. ESSIP Plan 2013 / Objective ATC 02.66

Finalisation Criteria Ensure that Ground systems have been upgraded to support the MSAW function. Ensure that the technical file (TF) with evidences of compliance and the EC declaration of verification of systems (DoV) has been delivered to the competent National Supervisory Authority (NSA). Ensure that the MSAW function is in operational use. Ensure that the training plans have been updated and a training package has been developed by the ANSP for the use of MSAW functions. ESSIP Plan 2013 / Objective ATC 02.67

Supporting Material The EUROCONTROL specification for MSAW issued in September 2009 (edition 0.9) which still a draft. The EUROCONTROL Guidance Material for MSAW issued in May 2009, Edition 1.0 This if for guidance only, and is not compulsory. ESSIP Plan 2013 / Objective ATC 02.68

ESSIP Report 2012 MSAW started to be implemented at ACC level by mid 90s across the ECAC area already. Progress has been made compared to Most States (23) declared to have plans for implementation by end ESSIP Plan 2013 / Objective ATC 02.69
