1. Objective ATC 02.6 ESSIP Plan 2014 Ingrid FEIJT DSS/PEPR 19.09.2014

2. ESSIP Plan 2014 / Objective ATC 02.62 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 authorities: Military ATC authorities are invited to consider implementation of MSAW level 2 when providing ATS surveillance services to GAT.

3. 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.

4. Link to European ATM Master Plan  [CM-0801] – Ground Based Safety Nets (TMA, En Route) ESSIP Plan 2014 / Objective ATC 02.64

5. 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 2014 / Objective ATC 02.65

6. 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 2014 / Objective ATC 02.66

7. 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  EUROCONTROL Guide ‘Safety Nets Ensuring Effectivenes’ dated 21 May 2011 This if for guidance only, and is not compulsory.  Council Decision of 30 March 2009 endorsing the European ATM Master Plan of the Single European Sky ATM Research (SESAR) project (2009/320/EC) ESSIP Plan 2014 / Objective ATC 02.67

8. ESSIP Report 2013  MSAW started to be implemented at ACC level by mid 90’s across the ECAC area already.  Progress has been made compared to 2012.  Most States declared to have plans for implementation by end 2016 end of the full operational capability date.
