New ATS system P1/VAFORIT at UAC Karlsruhe

DFS Deutsche Flugsicherung, Germany's air navigation services provider, introduced its new air traffic services (ATS) system P1/VAFORIT at Karlsruhe upper area control centre (UAC). January 2011 saw the successful conclusion of the initial operations phase.
With more than 1.3 million flights in 2010, UAC Karlsruhe is one of the busiest control centres on the European continent. It manages en-route air traffic over central and eastern Germany.

P1/VAFORIT replaces a mainframe-based system called KARLDAP, which had been in service for more than 30 years. The new system represents a paradigm shift in flight data processing. It is based on four-dimensional trajectory prediction and stripless operations. Such trajectory-based systems are the core of the Single European Sky ATM Research Programme (SESAR). They provide four-dimensional data about the planned flight paths of all flights relevant to a control centre. These features aid air traffic controllers in anticipating and resolving possible conflicts between aircraft and make flight planning more accurate, thus improving punctuality and reducing the number of re-routings.

Key features of P1/VAFORIT are:
  • 4D Trajectory Prediction
  • Advanced controller tools, such as Medium Term Conflict Detection (MTCD), What-If Probing and Flight Conformance Monitoring Aids (MONA)
  • Stripless operations
  • Automatic centre  centre coordination (OLDI 4.1)
  • Equipped for controller/pilot data link communications (upgrade in 2011/2012)
  • Two fully dissimilar radar data processors (RDP): a dual-redundant primary RDP plus a dual-redundant fallback RDP (PHOENIX including redundant display processors)
  • Mode S processing
  • Short Term Conflict Alert (STCA) and Area Proximity Warning (APW)
  • Synchronised Voice and Video Recording and Playback (VRAP)
  • Modular client/server system architecture
  • Up to 120 controller working positions (CWPs)
  • Concurrent processing of up to 1,500 tracks and 1,500 flight plans
  • Fulfilment of all relevant EU interoperability regulations

The implementation of the P1/VAFORIT system is part of the multinational iTEC (interoperability Through European Collaboration) programme of DFS and its UK and Spanish counterparts, NATS and AENA, together with Indra as their technology partner. The purpose of this programme is to improve interoperability between ATS systems of different countries. It also complies with the objectives established by the Single European Sky ATM Research Programme SESAR.
