    UK/Irish airspace

    • Status of UK PBN implementation

    – En-route

    – Terminal airspace

    – Navigation infrastructure

    • PBN capability survey

    • Summary

  • 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


  • 23 May 2011 5ICAO PBN TF5

    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


    •Ensure access to sufficient airspace for

    non CAT users

    •Provide flexibility within the system to

    enable future development and


    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


    • 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


    • 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


    – 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
