23 May 2011 3ICAO PBN TF5
The Future Airspace Strategy (FAS)
• UK is fully supportive of the ICAO PBN concept
• As a National Supervisory Authority, the UK CAA is not producing
a PBN Implementation Plan
– Implementation plans are the responsibility of the ANSPs/airports and
not the State/regulator
• CAA in conjunction with major stakeholders (NATS, Military and
Government Department) is putting in place a high level Future
Airspace Strategy
• Reflects the requirements of the Air Navigation Service Providers
(ANSPs) i.e., those responsible for the management of UK airspace
23 May 2011 4ICAO PBN TF5
The FAS sets out the strategy for modernising the UK airspace system
answering the question " "How can we make the most efficient use of
airspace, to meet users requirements, within future constraints?"
In scope for the FAS
• Maximising efficiency of the system within
safety and environmental constraints
• Integration with SES II and SESAR
• Balancing demand for airspace capacity
with supply - when and where it occurs
• Setting out the characteristics and
benefits of the future airspace system
• Roadmap for implementation of changes.
Areas not in scope but key to
delivering overall improvements
• The efficiency of airports’ operations
(scheduling, ground movements etc.)
• Government policy on airport development
• A detailed plan for implementation of the
proposed changes
• Alignment of industry investment plans to
implement changes
• Mechanisms to track the overall
performance of the system as changes are
implemented.

UK Airspace requirements for the future and the FAS Vision
UK Airspace Requires
Modernisation to:
•Deal with current hotspots of congestion
•Enable and facilitate continuous
improvement in safety
•Implement SES proposals
•Take advantage of technological
developments to improve efficiency
•Be responsive to Government policy and
decision-making
•Ensure access to sufficient airspace for
non CAT users
•Provide flexibility within the system to
enable future development and
advancements
FAS Vision
Safe, efficient airspace, that has
the capacity to meet reasonable
demand, balances the needs of all
users and mitigates the impact of
aviation on the environment
FAS Industry Implementation Group (FASIIG)
• Strategy drafted and consultation with
industry concluded in February 2011
• Final document to be published during the
summer of 2011
• Moving on to the next step
– FAS Industry Implementation Group (FASIIG)
23 May 2011 6ICAO PBN TF5
The 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 2015-2020 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 2015-2020 timescale or earlier where possible.”

Methodology
• How are we operating in 2020?
• What has changed since 2011 to get here?
– Airport Infrastructure
– ANSP
– Airborne equipage/operational approvals
– Regulatory/Government policy
• What challenges, dependencies and constraints were
overcome?
• What were the priorities?
• Interim steps
– What had we achieved by 2015?
– What did we achieve by December 2012?
23 May 2011 8ICAO PBN TF5
Scope
• Develop an implementation plan aligned 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 key
government and regulatory policy making (for
example Aviation Policy Framework)
• Identify key airspace, technical and policy
constraints to realisation of the FAS
23 May 2011 9ICAO PBN TF5
Regulatory Policies as Enablers to FAS
• A number of regulatory policy statements envisaged
– Policy for the Application of PBN in UK/Irish Airspace
– CAP 778, Policy and Guidance for the Design and Operation of Departure
Procedures in UK Airspace
– Introduction of B-RNAV in UK en-route airspace below FL 95
– Changes to the UK Ground Navigation Infrastructure
– P-RNAV Route Spacing
– RNAV Holding (in work)
– Proposed Change to UK and Irish Airspace Transition Altitude
– An “adapted” environmental consultation policy (CAP 725) (in work)
– Defining Routes Outside Controlled Airspace and Additional Protection at
Aerodromes for Public Transport Flights (policy proposals)
– Instrument Approaches To Aerodromes Without An Instrument Runway
and/or Approach Control (policy proposal)
23 May 2011 11ICAO PBN TF5
Policy for the Application of PBN in
UK/Irish Airspace
• The Future Airspace Strategy (FAS) sets out the
roadmap for development of UK airspace
• UK and Irish have jointly developed a FAB aligned
PBN Policy as an enabler to FAS
• Comprises 12 high-level policy statements
• Reflects the requirements of the Air Navigation
Service Providers (ANSPs) i.e., those responsible
for the management of UK airspace
• The PBN Policy sets out a specific framework with
guidance and support to ANSPs and operators to
help facilitate that development
23 May 2011 12ICAO PBN TF5
Objectives of PBN Policy
• The PBN Policy takes due account of:
– The current status of development of RNAV and RNP airspace,
routes and procedures within the UK
– The desire from operators to take greater advantage of on
board aircraft capability
– The desire of ANSPs to have a clearer framework for PBN
– The UK model for service provision, separate from State
control
– The future direction of the European ATM Master Plan and the
introduction of a PBN Implementing Rule circa 2018-2020
– Costs/business case involved in making any form of airspace
change
23 May 2011 13ICAO PBN TF5

Implementation Considerations
• Enablers
– General enablers
Political commitment necessary to realise FAS
– Specific enablers
Human, procedural or institutional and system enablers
– System enablers
Ground and airborne
– The interdependence of these enablers will necessitate
synchronised implementation

23 May 2011 ICAO PBN TF5 2020
Status of UK PBN Implementation
• 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
3 temporary exemptions issued so far
– NATS planning use of P-RNAV (RNAV 1) on trunk routes
• 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
– Trials of P-RNAV SIDs at Gatwick ongoing and likely to
result in permanent procedures
23 May 2011 21ICAO PBN TF5
Status of UK PBN Implementation
• Terminal Airspace continued..
– In October 2010, the London TC North project postponed
due to downturn in traffic levels since the first consultation
held in 2008
– TCN proposals to be incorporated into a wider review of
airspace over much of southern England
– Work is already under way in the London Airspace
Management Programme (LAMP) – see FASIIG initiative
– Changes in Manchester and Glasgow airspace also
planned based on a common template
23 May 2011 22ICAO PBN TF5
23 May 2011 23ICAO PBN TF5
Status of UK PBN Implementation
• Approach Operations
– Within the UK a high reliance on ILS
– ICAO General Assembly Resolution
A37-11 covering APV not realisable
in timescales
– Gradual uptake of GPS NPA
– APV Baro-VNAV at London
Heathrow, Gatwick (Manchester,
Belfast, Cambridge, Manston)
– Interest in APV SBAS at Alderney,
Southampton, HIAL and elsewhere
• CAA/NATS proactively supporting
APV stressing the safety and
business benefits
• Brochure published ( see opposite)
Status of UK PBN Implementation
• Approach Operations continued..
– IFP Design outsourced from CAA since April 2010 and two
organisations approved with two approvals pending
– Internal CAA processes being reviewed
– Communications being improved (web site)
• Navigation Infrastructure
– GNSS (GPS), with VOR/DME, DME/DME
– EGNOS available from March 2011
– NATS plans for decommissioning of all 10 en-route NDBs
– Rationalisation of VORs in three phases extending out to
2017, with a reduction from 47 to 19 facilities

PBN Capability Survey
• Plans for London Airspace Management Plan (LAMP) for 2014, 2016 and
2018 being developed
• CAA/NATS recognise that aircraft fleet mix is key to any change
• Alignment of operator fleet investment plans with airspace development
• Current fleet capability data is therefore required in order to inform the
airspace development process
– Ensure timely notification of technical requirements
– Ensure that the selected design standards can yield meaningful benefits i.e.,
cost benefits can be shown
• Use previous surveys to inform this assessment
– EUROCONTROL 2007
– IATA 2008
– EUROCONTROL/IATA 2010
• Identify the knowledge gap for the UK fleet and how this might be
addressed
• Will feed into FASIIG
23 May 2011 26ICAO PBN TF5
Summary
• PBN is one of the key components of FAS
• From a navigation and infrastructure perspective that means
embracing the concept of PBN and moving the UK controlled
airspace environment towards RNP
• PBN will only deliver benefits in conjunction with other
airspace changes
– Improvements in structure e.g., Transition Altitude and new
departure and arrival tracks
– ATM tools e.g., arrival and departure managers
• Aircraft fleet capability and approval status is a key factor
• Having the necessary regulatory and implementation
framework, policy and guidance is critical
• PBN Policy will be put to the test by LAMP for 2014, 2016 and
2018
