• Summary


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


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)


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?


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


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)


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


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


Scope and Assumptions

• What’s in scope

• What’s out of scope

– Environmental considerations

– Precision Approach and Landing Systems

– Overlay procedures

• Assumptions

– Medium term availability of Advanced RNP navigation

specification and its adoption within the PBN IR

– Early application of Advanced RNP in notified airspace


Policy Statements

• General

– Endorsement of the ICAO PBN Concept

– Application of PBN navigation specifications

– PBN mandates

• En-route

– Navigation specifications applied in the FAB

• Terminal Airspace

– Arrivals, Holding, Departures

• Instrument Approach Procedures

– Aerodromes encouraged to implement RNP APCH IAPs i.a.w. Resolution 37-11

– Runway classification

• Navigation Infrastructure

• Route spacing


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

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



• 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




• 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)


• 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


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
