The majority of UK flight paths were designed decades ago, at a time when aircraft and navigation were much less sophisticated than today. A nationwide airspace modernisation programme is therefore underway across UK airports.
Modernisation of the UK’s airspace is required to accommodate growing demand for air travel in a sustainable way. The Government has embarked on its airspace modernisation strategy which is being sponsored by the Civil Aviation Authority and the Department for Transport.
The aim of the strategy is to make airspace more efficient, to improve punctuality, to reduce CO2 emissions, to reduce noise and to ensure there is capacity to meet future demand. The strategy will require UK airports to modernise their airspace, as well as the airspace network above them, known as en route airspace. The UK’s Airspace Modernisation Strategy is part of ICAO’s Global Air Navigation Plan.
The Government’s strategic rationale for upgrading UK airspace provides more information on the need for airspace modernisation in the UK and describes the planned upgrades. The One Sky One Plan website provides more information about the benefits of airspace modernisation. Heathrow is working closely with the Airspace Change Organising Group ACOG and other airports to develop plans that integrate and work together across the UK.
Heathrow had initially proposed to undertake airspace modernisation through its Airspace Change Proposal (ACP) for Airport Expansion, but the Expansion project is on pause as the airport’s current priority is to recover from the COVID-19 pandemic. However, Heathrow remains committed to airspace modernisation and to keeping pace with the wider UK programme so we have begun a new ACP to make the necessary changes to flight paths to and from our existing two runways.
We have developed design principles for this airspace change, in collaboration with key stakeholders, and we submitted these to the CAA in February 2022. The CAA passed us at the Stage 1 Gateway and we are now at Stage 2 of the CAA’s process, where we are beginning to develop and assess potential route options. You can follow our progress on the CAA’s airspace change portal at: Airspace change proposal public view (caa.co.uk)
