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.

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

Operational Scenario at Perugia
• regional and general aviation
traffic;
• airspace constraints;
• mountainous terrain (also
affecting m.a.);
• RWY 01 ILS CAT I;
• 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.
