Contents Tasks achieved PBN implementation schedules On going activities Further aspects Conclusions 2
PBN Tasks achieved National PBN Task Force in place to tackle and handle PBN deployment inside National Airspace; Consultation with operators in progress by means of periodical ENAV Customer Care meeting; Spring 2011: Introduction of P-RNAV inside Italian airspace Summer 2012: Publication of National PBN implementation plan Regulator approval of National Safety Case for the introduction of RNP-APCH inside Italian Airspace Winter 2012: Publication of first RNP APCH procedure for Milan Malpensa and Milan Linate airports 3
PBN implementation Enroute phase Several new routes implemented according to RNAV 5 specification. Objective: Take advantage from PBN criteria to provide more direct routeings Since January 2012: 53 routes have been modified (22 Lower and 31 Upper) 22 new routes have been implemented (9 Lower and 13 Upper). Average gain approximately 3NM. 4
PBN implementation Arrival/Departure phases 2013 Implementation: LIEO: New P-RNAV STARs and SIDs for both runway ends, initially deployed as ATC Discretion ones. Achievements: Average track miles reduction: 11NM for arrivals; 1NM for departures Benefits: Arrivals/departures separated each other. Procedures enabling CDO/CCO. 5
STAR P-RNAV: Olbia Runway 23 6
STAR P-RNAV: Olbia Runway 05 7
SID P-RNAV: Olbia Runways 05/23 8
PBN implementation Arrival/Departure phases 2013 Implementation: LIPZ: New P-RNAV STARs and SIDs for runway 22. Achievements: Average track miles reduction: 7NM Benefits: Better traffic management on coded path, compared with the previous scenario (totally based on radar vectoring in order to maintain the same airport capacity) 9
STAR P-RNAV: Venice Runway 22 10
PBN implementation Arrival/Departure phases Planning: Several airports planned between winter 2013 and spring 2014: LIRQ: New arrival/departure network LIPE: New arrival/departure network LIMF; LIMC; LIME For LIMF and LIME the main objective is to provide P-RNAV arrival scenarios in order to deconflict arrival and departure flows enabling CDO/CCO operations. For LIMC the main objective is to provide a coded path to be flown in case of RWY 17 in use, whose radar minima downwind-base leg is affected by environmental constraints. 11
PBN implementation Approach phase RNP APCH procedures initially implemented with LNAV and LPV minima. Airports already involved: LIRF => Main runway ends (16L/R, 34L/R); LIML RWY 36, LIMC RWY 35L, LIPZ RWY 22L; Planning Next airports: Further 8 runway ends expected before next summer LIML (RWY 18), LIMC (RWY 35R), LIRQ (RWY 05), LIPE, LIMF (RWY 36), LIME; LIMJ Implementation, expected during next year, on two runway ends at the moment served only by circling approach (LIMJ RWY 10 LIPX RWY 22). Further objective: Introduction of BARO/VNAV (in addition to LNAV and LPV) on those runway ends served only by NPA conventional approaches, whenever practicable; 12
PBN implementation Training Air Traffic Controllers training completed PBN training plan Training modules on PBN familiarization and P-RNAV procedures, including operational aspects, planned starting from autumn 2012 for radar CTR. Venezia and Olbia Approach controllers training already completed Training module on GNSS approach procedure already performed in Milan and Rome TMA; Training modules for Procedure designers in the framework of continuous training activities; Training modules on PBN familiarization and P-RNAV procedures, including operational aspects, for ATCOs operating in radar CTR. Already planned: LIRQ (Florence). Next: LIPE (Bologna), LIMF (Torino) planned accordingly to implementation schedule; Training module on GNSS approach procedure for ATCOs planned accordingly to implementation schedule; Operational training modules on PBN and related procedure management for ATCOs instructors operating at ENAV Academy; Training modules on PBN familiarization for all people involved in operational activities; 13
PBN implementation On going activities LPV helicopter approach procedures developed and validated for Milan Linate and Bergamo airports in the framework of ACCEPTA Project; APV/BARO implementation. Assessment of present vs future criteria has been performed on a test airport (LIMC). Results show that new criteria need a new assessment of instrument flight procedures already published with the old criteria. GNSS monitoring: Activities in progress in order to deploy a national GNSS strategy and to overcome some of the Safety Requirements needed for the implementation of RNP APCH procedures. CDO operations: The objective is related to develop tailored P-RNAV Stars available for planning or to support CDO operations to existing STARs with embedded level windows. Target date: Spring 2014. Target airports: LIML, LIMC, LIRF. 14
PBN implementation Further aspects Design/Coding aspects: Strong interactions between design issues, coding issues and FMS storage capacity=> especially related to MAPt position and number of procedures to be coded inside FMS. Improve operators awareness on PBN availability and use => Pilots requests for radar vectoring even if cleared on P-RNAV segments. Future issues: Which actions need to be put in place by each stakeholder in order to support the transition of GNSS towards primary means of navigation? Proactive approach needed in order to take advantage by some lessons learnt in the past. 15
Conclusions Italy is working accordingly to the published National PBN implementation plan; Several procedures have been already published on each flight phase; Training modules available and completed on sites where PBN procedures are on air; Several activities in progress: GNSS monitoring activities in progress in cooperation with our Regulator; RNP APCH safety case update; Introduction of BARO/VNAV whenever practicable; Allow for CDO on new (RNAV1) Stars/existing Stars; Aspects to tackle: RNP APCH and coding issues; Improve operators awareness on PBN availability and use; Proactive approach to move towards GNSS as a primary means of navigation taking advantage from lessons of the past. 16
