From today, NATS is introducing Direct Route Airspace into Prestwick’s Rathlin and Central upper airspace sectors.
The first flight through the new Direct Route Airspace was United Airlines UAL989 at 03:51 this morning on its way to Frankfurt. You can listen to the RT between the controller – Victoria Lever – and the pilot below.
This is a real landmark which will lay our foundations for the eventual adoption of Free Route Airspace across the whole of Northern Europe, which we’re aiming to achieve by 2020 in collaboration with our partners in the Borealis Alliance.
We spoke to Branka Subotic, who recently took over as Executive Director of the Borealis Alliance, and Prestwick Centre’s ATC Lead, Ian Gott to get an insight into the Free Route Airspace programme.
Why don’t we have Free Route Airspace in the first place?
Ian: The routes traditionally used around the world were decided many decades ago, when navigational techniques and telecoms technology were very different. At the time it made sense to think of routes much like fixed motorways in the sky. As a result, to get from A to B you’d travel along one corridor until you got to a junction that let you change direction towards your destination, which is clearly not the most direct route.
The next step up from this scenario is Direct Route Airspace, where you can simply fly from A to B directly, bringing obvious fuel and time savings. But the ultimate goal is Free Route Airspace, where you have freedom to take the optimal route based on other factors such as weather and wind speeds.
Allowing that sort of flexibility seemed impossible in the past due to safety issues, but as technology has moved on, and cross-border collaboration has improved this is no longer an issue.
Will Free Route Airspace get introduced immediately at Prestwick Centre?
Ian: No. It will be a phased process, starting with the introduction of Direct Route Airspace (DRA) within the Central and Rathlin airspace sectors, and then moving to Free Route Airspace in the Scottish Flight Information Region before being extended to the London Flight Information Region.
To put DRA into context, this introductory programme alone is expected to deliver over 300 direct routes, with annual savings of 3,000 tonnes of fuel, worth more than £1m a year to our customer airlines.
What is the Borealis Alliance?
Branka: In the summer of 2012, the ANSPs of Denmark, Estonia, Finland, Iceland, Ireland, Latvia, Norway, Sweden and the UK formed an alliance aimed at improving efficiency, reducing costs and delivering environmental improvements through business collaboration.
The Borealis Alliance aims to drive joint initiatives and build on the success of existing collaboration between the partners through their Functional Airspace Blocks (FABs), but with a focus on business-driven cooperation as opposed to the political cooperation which is required through FABs.
What will the Borealis Free Route Airspace programme deliver?
Branka: It will provide a specified airspace within which users may freely plan a route between a defined entry point and a defined exit point, with the possibility to route via intermediate (published or unpublished) way points, without reference to the route network, subject to airspace availability.
In essence, this means airspace users can plan and fly the most cost effective, fuel efficient and timely routes across the entire airspace managed by Borealis Alliance members rather than following pre-defined routes within each member country’s airspace, saving time, money and fuel. This will all be possible within the Borealis Alliance airspace.
Through this programme, Free Route Airspace already exists in Iceland, Ireland, Denmark and Sweden, and will be extended to Estonia, Finland, Latvia and Norway in 2015 and to the UK in stages from 2017. When fully realised, we will have created Free Route Airspace across northern Europe from the eastern boundary of the North Atlantic to the western boundary of Russian airspace.
How is NATS involved in the Borealis Alliance Free Route Airspace programme?
Branka: As one of nine partners, NATS is an integral part of the Free Route Airspace programme and, given the amount of flights that fly through UK airspace, they are integral to maximising the benefits of the Free Route Airspace programme to airspace users. NATS’ commitment to the Alliance and its activities is reflected by the fact that our CEO Richard Deakin is the newly appointed Chair of the Borealis Alliance Board, while I have been seconded to act as its Executive Director.
