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)
• SBAS LPV (or 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.

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).

• 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).

– 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).
Risk Assessment and Mitigation (ESARR4)

• 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.
