Delivering a Future Airspace Strategy (FAS)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 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.”


Delivery of FASDelivery 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


PBN Regulatory Enablers 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


ANO Articles 124/125ANO 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


Policy for the Application of PBN in UK/Irish AirspacePolicy 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


PBN CaveatsPBN 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


AIC - Application of PBN in UK AirspaceAIC - 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 StatusCurrent Status202 July 2012 10ICAO-EUR PBN TF/7

Current StatusCurrent 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



• 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

• 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

Other DevelopmentsOther 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


Trial of RNP 1 Departures with RFTrial 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


• 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

CAA Policy Regarding Instrument Approach Procedures To Aerodromes Without an Instrument Runway and/or Approach Control

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


Navaid RationalisationNavaid 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

SummarySummary302 July 2012 21ICAO-EUR PBN TF/7

SummarySummary

• 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

SummarySummary

• 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
