3. Delivering a Future Airspace Strategy (FAS)
The FAS Industry Implementation Group (FASIIG) Objective:
“To work collaboratively across the aviation industry (NATS, CAA, Airports, Airlines, Military, GA) to develop and agree an implementation plan to deliver the CAA’s Future Airspace Strategy for the timescale. The FASIIG will work within a fixed two year timescale in order to deliver an implementation plan which delivers a set of tangible benefits within the timescale or earlier where possible.”

ICAO-EUR PBN TF/7

4. Delivery of FAS Develop a FAS Implementation Plan by end of 2012
Align it to near and longer term SESAR objectives
Monitor & manage the action plan to ensure timely progress
The FASIIG will provide the opportunity to develop cross industry positions for input to government and regulatory policy making
Identify key airspace, technical and policy constraints to realisation of the FAS
PBN seen as a key element of the FAS implementation plan

5. PBN Regulatory Enablers
UK Air Navigation Order (CAP 393) Articles 124/125
Area navigation and required navigation performance capabilities
Aircraft registered in the UK (124)
Aircraft registered elsewhere than the UK (125)
Policy for the Application of PBN in UK/Irish Airspace
02 July 2012
ICAO-EUR PBN TF/7

6. ANO Articles 124/125
An aircraft must not fly in required navigation performance airspace unless it is equipped with area navigation equipment which enables the aircraft to maintain the navigation performance capability notified, prescribed or otherwise designated for that airspace
The equipment must be approved, installed in an acceptable manner, maintained and operated in accordance with approved procedures
An aircraft need not comply with these requirements if ATC, having been made aware of the lack of compliance, authorises the flight or the aircraft complies with any ATC instructions

ICAO-EUR PBN TF/7

7. Policy for the Application of PBN in UK/Irish Airspace
Approved at FAB Supervisory Committee Meeting in Dublin on 13 October 2011
Comprises 12 high-level policy statements
The PBN Policy sets out a specific framework with guidance and support to ANSPs and operators to help facilitate implementation
Subject to review and update in late 2012
02 July 2012
ICAO-EUR PBN TF/7

8. PBN Caveats
PBN is only one element of technological and operational enhancements providing enablers for FAS
Environmental policy, cost and business drivers will have an impact on how quickly PBN can be moved forward
The PBN Policy does not contain all of the answers to implementation issues, these will have to be developed separately through the UK/Irish PBN Implementation Working Group

ICAO-EUR PBN TF/7

9. AIC - Application of PBN in UK Airspace
Approximates to a UK PBN Implementation Plan
A roadmap for ANSPs and Airports seeking to introduce PBN as part of their airspace changes
Intended to provide framework for LAMP and NTCA
Link to Air Navigation Order (ANO) Articles 124 and 125
Still very much an enabling AIC
Sets out 2014, 2016 and 2018 objectives based on anticipated aircraft capabilities
AIC needs to be read in conjunction with PBN Policy document
Yellow 023/2012 refers

Current Status
02 July 2012
ICAO-EUR PBN TF/7

11. Current Status En-route
From 7 April 2011, B-RNAV (RNAV 5) became applicable on all UK ATS routes at all levels/altitudes in controlled airspace as promulgated in the UK AIP
02 July 2012
ICAO-EUR PBN TF/7

12. Current Status Terminal Airspace
Still no P-RNAV (RNAV 1) SIDs or STARs implemented, although STARs are largely covered by the extension of the B-RNAV mandate
NATS London Airspace Management Programme (LAMP) and Northern Terminal Control Area (NTCA) Projects
Gatwick RNAV 1 SIDs (transposing trials to permanent procedures)
Newcastle RNAV 1 SIDs, Leeds/Bradford RNAV 1 SIDs and STARs
02 July 2012
ICAO-EUR PBN TF/7

13. Current Status RNP APCH implementation today
High levels of interest to implement RNAV (GNSS) Approaches
APV Demand may exceed IAP design and regulation capacity
Profile raised by EC 7th Framework Funding call for LPV implementation (ACCEPTA)
14 aerodromes successful in UK
All will include LNAV Reversion
CAA encouraging inclusion of LNAV/VNAV Minima on charts where beneficial
Runway ends

14. Other Developments SID and NPR Working Group:
Define the components of instrument departure procedures promulgated either conventionally or utilising PBN (RNAV/RNP)
Identify and clarify the issues surrounding the replication of conventionally promulgated Standard Instrument Departures (SID) and any associated Noise Preferential Routes (NPR)
Propose possible solutions to any issues identified above
02 July 2012
ICAO-EUR PBN TF/7

15. Trial of RNP 1 Departures with RF
Conducting feasibility assessment for potential RNP 1 with Radius to Fix (RF) Departure trials at London Stansted RWY 04 DVR and RWY 22 CLN
Trial commencement – after the London 2012 Olympics
02 July 2012
ICAO-EUR PBN TF/7

16. RNAV Holding Policy Objective: To publish RNAV Holding Policy
Ensure that the RNAV hold and STAR is at least as safe as the current conventional procedures
Hold separation standards
Hold to adjacent hold
Hold to route or edge of Controlled Airspace
02 July 2012

17. CAA Policy Regarding Instrument Approach Procedures To Aerodromes Without an Instrument Runway and/or Approach Control
Development of Policy and Guidance (CAP)
Consultation over the summer of 2012
Publication by end of 2012
02 July 2012
ICAO-EUR PBN TF/7

18. Navaid Rationalisation
NATS programme to “right-size” the UK conventional navigation infrastructure compatible with a PBN environment
Consistent with changes to require RNAV 5 on all UK ATS routes since April 2011 and AIC Yellow 107/2011 allowing Routes and Procedures to be flown with an equivalent to ADF
Removal of 8 en-route NDBs by 2018
Reduction of en-route VORs from 46 to 19 by 2018
VOR dependencies:
Terminal airspace conventional procedures e.g., SIDs
Instrument Approach procedures
Use for training (civil and military)
Means of procedural separation
Mitigation against controlled airspace infringements
Fragmented ownership of airports/procedures

22. Summary
PBN is a key enabler for the Future Airspace Strategy (FAS) and indeed, the CAA Environmental Strategy
CAA PBN Policy in place
Industry implementation programme now being developed by the FASIIG
AIC (Y) 023/2012 sets out the application roadmap leading into the introduction of the SES PBN IR
RNP APCH offers access for all types of aircraft and to all aerodromes*
Processes established to assist in deployment and CAA working to smooth the approval path
* Emerging CAA policy for Non-Instrument Runways and where No-Approach Service available

23. Summary Navigation infrastructure is part of the PBN solution
NATS VOR replacement programme is therefore an opportunity to “right-size” UK navigation infrastructure through rationalisation
Through FAS, the CAA is seeking to modernise and future-proof UK airspace and infrastructure
