Introduction of EGNOS operations: the perspective of an Air Navigation Service Provider

METIS Workshop

Benefits of EGNOS in Civil Aviation

Istanbul 18 November 2009

single european sky ses objectives
to increase: safety, efficiency, capacity of ATM in Europe;

to reduce fragmentation / complexity of airspace (FABs, FUA);

to provide a framework for modernisation of systems (SESAR);

to reduce the environmental impact of any operation.

… widespread PBN operations key enablers of SES.

Single European Sky (SES) - Objectives

METIS Workshop Benefits of EGNOS in Civil Aviation, Istanbul 18 November 2009

pbn approaches rnp apch baro vnav
first step of PBN implementation;

operational benefits (flight time, pilot / controller workload, repeatability of the flight path);

vertical Baro-guidance for equipped aircraft (some models of Airbus and Boeing);

Baro VNAV flight procedures where cost-effective;

RNP APCH subject to some operational restrictions (i.e. RAIM availability).

PBN Approaches – SBAS LPV (or SBAS APV)
  • increased availability by SBAS (no RAIM);
  • access to both greatest and regional airports;
  • EGNOS LPV suitable for at least 70% of Italian RWYs (good average visibility in Central/Southern Italy);
  • EGNOS LPV suitable at Perugia (LIRZ) airport.
  • SBAS LPV (or APV)

regional and general aviation traffic;

airspace constraints;

mountainous terrain (also affecting m.a.);

Procedural surveillance;

IFR RWY 19 desirable (in case of south wind).

Overall PBN Implementation steps in EU

  • certification of airborne equipment;
  • obligations of aircraft operators (manuals, crew training);
  • radio navigation signals of sufficient performance (ESSP in the case of EGNOS);
  • airspace design + aeronautical information publication (Service Providers);
  • subject to regulation/approval by “EASA system” (including NSAs).

International Projects join different stakeholders !

Risk Assessment and Mitigation (ESARR4)

  • Service Providers shall carry out Safety Assessment of the intended modifications (SES Regulation);
  • Local constraints key factor;
  • High-level Safety Cases as inputs to Local Safety Assessment;
  • possible local degradation of signals (e.g. GPS interference) and mitigations (ICAO ANC/11, Recommendation 6/2).

Conclusion

  • Performance Based Navigation (PBN) one of the key enablers of SES;
  • Aeronautical Information Management required for PBN;
  • RNP APCH (+Baro) the first implementation step of PBN;
  • SBAS LPV suitable for at least 70% of Italian runways end;
  • Despite of the conservative concept (ILS-look-alike), LPV introduces the required level of automation with accurate flight path repeatability by means of EGNOS signal availability.
