1 Status of PBN implementation in France PBN TF/4 Dec 2010 Benoit ROTURIER (DSNA) 1

2 Context supporting DSNA navigation strategy ICAO Navigation strategy Performance Based Navigation (PBN) concept Resolutions of the ICAO 36 & 37th Assembly Eurocontrol Navigation strategy & GNSS policy Airspace users discussions SESAR Rationalisation of Conventional navaids (VOR, NDB, ILS cat I) Strategy (ANSP level) PBN Impl. Plan (State level) 2

3 User needs identified for short term PBN implementation Major airlines needs RNAV 1 arrival/departures within large terminal areas Re-inforce the GNSS approaches with vertical barometric guidance (APV Baro-VNAV) Introduce RNP Approaches with Authorisation for specific gains Business Jets Area navigation path supporting increased airport accessibility, safety and high performances. Supports GNSS approaches with GNSS vertical guidance (APV SBAS) Helicopters Supports GNSS approaches with APV SBAS, Medical Evacuation RNAV 1 arrival/departures Other General Aviation Supports GNSS approaches with ABAS & APV SBAS 3

4 PBN Operations in France 2010 PBN Type NavSpec RNAV RNP Name NavSpec RNAV5 RNAV1 RNP APCH RNP AR APCH Flight Phase Procedure designation En-route Airways SID Terminal STAR INA Approach NPA RNAV (GNSS) Approach APV Special Approach with authorisatio (study) Minima Designation LNAV (NPA) LNAV/VNAV (APV baro) LPV (APV sbas) 4

5 Chart Naming Convention for RNAV 1 and RNP APCH implementation IAF IF FAF/FAP SID RNAV (GNSS, DME/DME) STAR RNAV (GNSS, DME/DME) INA RNAV (GNSS, DME/DME) FNA RNAV (GNSS) RWY xx FNA ILS RWY xx RNAV (GNSS) RWY xx En-Route Departure Arrival Approach Note: RNAV current naming for SID, STAR, INA to be revisited, possibly using RNAV 1 alternatively 5

6 RNAV 1 DSNA strategy Since 2008, most new RNAV applications in TMA are supported by RNAV1 End 2010, 17 RNAV 1 studies launched, 7 RNAV 1 publications Progressive shift from existing TMA B-RNAV + to RNAV 1 RNAV 1 supports current CDA experimentations Paris, Toulouse, Strasbourg, Main hurdles Migration to RNAV 1 launched on a case by case basis, when local ATC dispositions are reviewed Lack of a mandate for aircraft equipage, slow migration in TMAs where the ATC cannot handle a diversity of users without compromising efficiency. Some new RNAV applications supported by RNAV 5 To include more users within the application Ex: Nice high altitude arrivals 6

7 RNAV 1 chart example Constant Descent Approach (CDA) experiment in Toulouse Blagnac PRNAV implementation in Nice 7

8 RNP APCH DSNA strategy (1/2) Final target is full compliance with 37th Assembly resolution (2016) Initial implementation is LNAV End 2010, 115 RNP APCH with LNAV minima studies launched, 50 have reached publication Close to Assembly 37, resolution A36/1, objective of 30% of runway ends by 2010 No specific hurdle identified for LNAV 8

9 RNP APCH DSNA strategy (1/2) All RNP APCH approach will support LPV minima: End 2010, 22 RNP APCH with LPV minima studies launched, 1 has reached publication (see hurdles) Main hurdles for LPV Delay in EGNOS SoL declaration Limited user equipment (AMC expected ASAP) RNP APCH with LPV minima expected to replace some ILS Cat I France has a large number of ILS Cat I DSNA strategy is: ILS Cat I not replaced since 2010 on smaller airfields 2015 Strategy fo larger airfields to be reviewed next year 9

10 LPV approach chart example : Pau 10

11 LPV approach chart example : Clermont Ferrand existing minima VOR/DME: 500 ft ILS Cat A: 260 ft Cat C: 280 ft 11

12 RNP APCH DSNA strategy (2/2) RNP APCH with BaroVNAV vertical guidance (LNAV/VNAV minima) implemented in coordination with airspace users: Implementation coordinated with Air France (priority list of 28 runways) End 2010, 1 RNP APCH with LNAV/VNAV minima studies launched, 0 has reached publication (see hurdles) Brest will be the first RNP APCH published (2011) with three minima line LNAV (370 ft), LNAV/VNAV (370 ft), LPV (250 ft or 300 ft depending runway classification) Main hurdles for LNAV/VNAV Lack of finalized safety case (Eurocontrol) Depending on mitigation of QNH errors, specific ATC/Aircrew phraseology to be defined Users already equiped not yet qualified vs. AMC

13 RNP APCH user forum DGAC organizes three times a year meetings with major industrial partners and DGAC key experts to discuss APV EGNOS implementation : Airbus France (A 350 LPV certification) Airbus Transport International (ATI) operating Beluga Dassault Aviation (cockpit EASy II certification) Eurocopter Thales Avionics Eurocontrol ESSP For APV Baro VNAV, a DGAC working group has been setup with one major airline participation Air France 13

RNP APCH European projects DSNA participates to: Beluga project sponsored by Eurocontrol to equip and certify one Beluga Aircraft with LPV capability (AMC 20-28) and to publish one

14 RNP APCH European projects DSNA participates to: Beluga project sponsored by Eurocontrol to equip and certify one Beluga Aircraft with LPV capability (AMC 20-28) and to publish one LPV procedure Beluga Certification expected 1st half 2011, using Pau LPV procedure Accepta project, partially sponsored by GSA (FP7) with the objective to publish 3 LPV in France. 14

15 APV implementation vs. ICAO docs Operation Classification (Annex 6) Charting and minima standards (PANS OPS) Signal performance requirements (Annex 10 GNSS or PBN manual BaroVNAV ) Runway classification (Annex 14) Under approval by National airspace authorities Resulting Operation from the combination of different ICAO requirements (PBN manual including the new RNP APCH Nav. Spec.) RNAV(GNSS) charting Cat I NPA RNP APCH down to LPV 300 ft PA Cat I, II, III RNP APCH down to LPV 200 ft APV LPV minima APV I or II NPA RNP APCH down to LPV 300 ft PA Cat I, II, III RNP APCH down to LPV 250 ft RNAV(GNSS) charting LNAV/VNAV minima BaroVNAV Attachment NPA RNP APCH down to LNAV/VNAV 300 ft PA Cat I, II, III RNP APCH down to LNAV/VNAV 250 ft!! APV implementation to different range of minima using the material in current ICAO docs is possible now!! 15

16 Return of experience Phraseology for RNP APCH 6 different cases in theory: IAF IF FAF/FAP INA conventional Radar guidance INA RNAV 1 (GNSS, DME/DME) FNA conventional FNA RNAV (GNSS) FNA conventional FNA RNAV (GNSS) FNA conventional FNA RNAV (GNSS) ICAO phraeology seems not fully complete to handle all of these cases, including specific BaroVNAV mitigations required by the Eurocontrol Safety case 16 Coordination at ICAO level required to support full RNP APCH implementation

17 Conclusions A lot of operational experience has been collected through the deployment of RNAV 1 and RNP APCH in France Now documented within an exhaustive DSNA PBN course Devoted to RNAV 1 and RNP APCH implementation Used for the initial and on site formation of DSNA operational staff (ATC, etc..) ICAO material supporting APV implementation is exhaustive, and has been used by France Complement to be made to phraseology? Charting? Existing ICAO approach classification, including APV, is sound and not expected to change Completion of Eurocontrol APV generic safety cases now required DSNA has now developped exhaustive safety material for all other PBN applications Completion of EASA AMC and now required PBN plan for France publication expected
