ESSIP Plan 2015 / Objective ATC 02.5 2

Comprehensive Explanation (1/2)

Implementation of Area Proximity Warning (APW) function

ECAC applicability

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 APW level 2 when providing ATS surveillance services to GAT

Comprehensive Explanation (2/2)

APW 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 protected airspace.

Protected areas might be restricted, danger or prohibited zone or Temporary Segregated Areas (TSA) or Temporarily Restricted Areas (TRA).

Conflict is declared if a/c track infringes the protected airspace or intends to do so in short distance in time (</= 2 minutes).

Some FP data like Cleared Flight Level (CFL) might be used in case of temporarily absence of Mode – C.

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

Most important SLoA(s)

ASP01 “Implement the APW function to put into service ground-based safety tool systems and associated procedures supporting the APW function in En-Route airspace, applicable TMAs and Military ATC units providing surveillance services.” ASP to check the compliance of implemented APW with the

requirements stated in the Specification, the related guidance material and the relevant training and safety requirements.

Finalisation Criteria

Ensure that Ground systems have been upgraded to support the APW 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 APW 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 APW functions.

Supporting Material

The EUROCONTROL specification for APW has been issued in May 2009 (edition 0.5) which still a draft, as well as the related guidance material. This if for guidance only, and is not compulsory.
