Every year, we ask you to rate us on partnership, performance and progress.
In 2015, we achieved our highest-ever score, 8.45 out of 10.
We’re pleased with what is an overall positive assessment. The survey covers all aspects of our service to you and we ask you for feedback on your priorities and areas where we need improve. Thank you to all who contributed to the survey. It’s something we take seriously and follow up on and wanted to share the key findings with you.
We’ve re-focused the airports’ customer survey to help us understand more closely what’s important to you and in a way that we can respond more effectively to your feedback.
While this takes in airport customer satisfaction and safety, service and communications as a matter of course, we also want to be sure we’re focusing on activities which are part of driving success for your business.
You have told us that operationally NATS provide an excellent safe and resilient service but you’d like us to improve how we respond to you from a business perspective. Your feedback underlined our continuing experience that airports want to work alongside us much more so that we can help with broader airport solutions.
This includes enhancing ATM efficiency across airports, such as the introduction of smarter processes, enhanced automation and making the most of ATC staff expertise.
As examples we are rolling out improved Meteorological Observations technology, providing automated weather readings. And when conditions permit us to do so safely, we’re combining radar and aerodrome positions within the tower which provides further resilience, improves efficiency and the ability to meet changing demands of schedules without an increased cost to airport ATC operations. Looking to the future we will be deploying Remote Tower to support airport operations where needed.
In 2015, no category A or B Airproxes † – those that were risk-bearing - were recorded which were attributable to NATS. There was however an increase in the low level Airprox events – category C and D events which were the result of drones or RPAS (Remotely Piloted Airborne Systems), which increased from 41 to 66 events in NATS Airspace between 2014 and 2015. These numbers are characteristic of the rise in RPAS activity in the UK. This use of RPAS will continue to evolve and grow and NATS is ensuring it, too, develops effective relationships and procedures to enable it to operate safely as part of an ever-more complex air traffic network.
More broadly, following 10 years of continuous improvement in operational safety performance, 2015 was not quite as good. In line with our RP2 commitment to reduce safety risk per flight in line with traffic growth, we are undertaking tactical activities and strategy improvements to meet this target.
As part of our improvement activities we have introduced the new Risk Analysis Tool (RAT) methodology – mandated across all European States as of January 2015. The RAT has enabled us to examine all operational losses of separation from a different perspective and gaining a great understanding of the factors driving our performance.
There was also much to be positive about in the area of technological advancement. By way of demonstration, our controllers managed the first flight by an unmanned aircraft in civil, controlled airspace in September, paving the way for safe integration of RPAS.
† Airprox – A situation in which the opinion of a Pilot or Controller, the distance between aircraft as well as their relative position and speed, have been such that the safety of the aircraft involved may have been compromised.
Safety apart, the critical measurement of how well we manage the air traffic network is the delay to flights which can be attributed to us.
The graphic below is a snapshot of what that looks like in practice. Against an agreed target of 10.2 seconds per flight, our teams achieved 2.4 seconds. The number of flights rose from 2.22 million to 2.38 million in 2015.
In summary, only 0.2 per cent of flights were delayed as a result of our operation. We always strive to improve but 99.8 per cent of flights not affected by delay attributable to NATS is a strong result. Setting it against the average European ATM delay – ten times higher - is a further positive indicator.

At the start of last year, we announced we were ahead of our projected target of 4 per cent at 4.3 per cent to reach a reduction of 10 per cent in ATM CO2 by 2020. By the end of 2015 this figure was at 4.6 per cent.
Over 1.1 million tonnes of aviation-related CO2 is now being saved each year. The reduction equates to more than £109m in enabled fuel savings†.
Working directly with you through the Flight Efficiency Partnership has also brought benefits. Together, we’ve been able to make incremental adjustments to improve the fuel efficiency of selected procedures. A combination of procedural and tactical improvements like this helped save 10,600 tonnes of fuel in 2015.
† Based on an average fuel price of £315 per tonne for 2015-16.
Time-Based Separation (TBS) won two prestigious awards this year, further recognition of the benefits it delivers for airlines and airports.
Together with project partners Lockheed Martin, Heathrow Airport and Eurocontrol, the innovation was named winner in the European Commission's debut Single European Sky award.
Held in Madrid as part of CANSO's World ATM Congress, the awards celebrate the best examples of collaborative working within air traffic management to make Single European Sky a reality.
This success came after the team won the IHS Jane's ATC Runway Award, also held at the Madrid conference.
Time-Based Separation (TBS) allows us to manage dynamically the separation between arriving aircraft based on the prevailing wind conditions at Heathrow.
During strong headwinds, aircraft fly more slowly over the ground which has traditionally resulted in extra time between arrivals and consequently delays to arriving flights. However, TBS has allowed us to maintain the landing rate in headwinds by safely reducing the distance between arrivals.
In November 2015 alone, we estimate TBS saved 25,000 minutes of delay, despite winds of up to 60 knots on final approach. On 10 November, despite a 40 knot headwind, we had no flow regulations in place at all, something that would have been unthinkable before.
On average TBS has allowed us to land 2.9 additional aircraft an hour on strong wind days and cut Air Traffic Flow Management delays caused by headwinds by up to 60 per cent. Importantly, this has all been achieved without any increase in reported wake vortex encounters or go-arounds.
British Airways' Director of Operations
Our collaboration with fellow air navigation service providers (ANSPs) on Extended Arrival Manager (XMAN) has continued to streamline the flow of aircraft into Heathrow. Working with controllers in France, Belgium, the Netherlands and Ireland, aeroplanes can be slowed before they are near UK airspace.
What began as a trial has been so successful that it entered permanent operational service last October.
This procedure can now begin 350 miles from London. Previously, controllers could only influence aircraft speed once it was in the NATS network, only 80 miles from the airport, limiting the ability to manage inbound traffic flows.
Heathrow operates at 98 per cent capacity and relies on holding stacks to ensure the runways are used as efficiently as possible. XMAN cut by up to a minute the time spent holding, saving fuel and reducing noise for nearby communities.
Co-ordinating with other ANSPs to manage aircraft speed across each stage of their journey – slowing or accelerating depending on the type of delay - will ultimately deliver significant efficiency improvements.
XMAN is a key concept of the Single European Sky initiative, which will require 24 airports across Europe to deploy XMAN procedures by 2024, ensuring the benefits are felt more widely.
Over the North Atlantic, we have successfully introduced RLat or reduced lateral separation. By working with our colleagues in NavCanada, we have reduced separation side-by-side with other aircraft from a degree of latitude to half a degree. Pilots can now request more efficient flight levels and save fuel.
This reduced lateral distance is set to become the standard separation minimum across the organised track structure later this year.
Customers have also been experiencing the benefits of the tools we introduced for our Oceanic controllers at the end of 2014. The latest technology monitors pilots’ requests for more efficient flight levels and speeds and advises controllers when these become available. If flight crews are too busy to make the request, the tools can automatically look for opportunities for aircraft to climb which the controllers can offer to the crews if it is safe to do so. It’s estimated that Oceanic improvements will save 30,000 tonnes of fuel a year because of the extra capacity created.
Operations Director, NATS Prestwick
Over the last year, we have been working very closely with Heathrow to drive forward our strategic partnership. Like our work with other airport colleagues, we have built up an intimate knowledge of Heathrow’s day-to-day and strategic operation. In 2015, our Heathrow General Manager, Jon Proudlove, began a secondment as the airport’s Director Airside Operations and this will continue in 2016. Both our organisations have benefited from the partnership, and this way of working we will be progressing with other airports this year.
Elsewhere, the market to manage air traffic control at individual airports continues to become more competitive. We were delighted to renew our contracts for tower operations with Belfast International, Sumburgh Approach Services and East Shetland Basin ATC services.
Evidence, if it were needed, of growing competition was seen at Gatwick. A new operator has now taken over tower and engineering services. We are very proud of our track record at Gatwick, which is, by a large margin, the busiest and most efficient single runway in the world.
Last summer, we delivered a record 934 movements in a single day. We have worked closely with the airport to ensure a safe and professional transition, including seconding 24 employees to support the new Gatwick ANSP whilst they train their own team.
Heathrow Airport Operations Strategy Director
The airspace change proposal for the first phase of London Airspace Management Programme (LAMP1A) was approved by the Civil Aviation Authority last November and was implemented in February this year.
The changes clear the way for wider modernisation of airspace to deliver more efficient flights, saving fuel and reducing CO2 emissions, and reducing noise, keeping aircraft higher for longer and minimising areas regularly overflown.
The changes include:
As you may have just read in the operations update, we successfully brought in the first phase of airspace change (LAMP1A) in February this year.
However, planned consultation with the public on airspace change and the UK Government policies including the treatment of noise, unprecedented public reaction to change in noise patterns and an impending government decision on runways in the south-east now colour the landscape against which low-level airspace change is set.
Public reaction over uncertainty about runway expansion, in particular, has fed into airports reconsidering the second phase of low level airspace changes proposed over London (LAMP2). These were scheduled for full implementation by 2019 but are now planned to take place in the next five-year regulatory charging period, RP3, which begins in 2020, by when aviation policy should be set.
In the meantime we are continuing our work to implement the higher level changes to the London terminal airspace from the original LAMP design. We’re also working with airports to redesign the airspace in the Scottish Terminal Manoeuvring and Northern Terminal Control Areas in a coordinated approach. This is expected to enable fuel savings of between 32,000 to 42,000 tonnes per year.
“Without meaningful and widespread airspace modernisation, the UK faces the prospect of delays many times what they are today, something that will cost airlines many millions of pounds each year and our wider economy an awful lot more. In reality the breakdown in connectivity would likely mean the erosion of our aviation industry with airlines taking their business elsewhere.
The challenge with airspace change, as with every other big infrastructure project, is that there are always winners and losers and it therefore requires political determination to help deliver. But the stakes are high and as an island nation that relies on aviation, we can’t afford to lose."
NATS Operations Director
Our part in the effort to create a single area of Free Route Airspace (FRA) covering nine North European Countries by 2021 was recognised by the European Commission in its first-ever Single European Sky Awards ceremony.
The Free Route Airspace will extend from the eastern boundary of the North Atlantic to the western boundary of Russian airspace in northern Europe. It will enable airspace users to plan and take the most cost-effective, fuel-efficient and timely routes across the entire airspace managed by Borealis members rather than following pre-defined ‘routes’ within each member country’s airspace, saving time, money and fuel. This will provide significant savings in fuel and CO2 emissions to customers.
We took our first step towards FRA with Direct Route Airspace in portions of Scottish airspace last year and we’ll be introducing FRA itself into areas of Scottish airspace before extending more widely across the UK.

Rare is the customer report which features a major project with no impact whatsoever on its customers. But that’s what happened when we moved our Area operation out of its control room at Swanwick to a new home, next to the Terminal Control teams.
The transition to new space in the centre was completed with no interruption to your flight operations. Business-as-usual despite a significant transition.
The impetus behind this major project is to ensure we are deploying the technology needed for future air traffic requirements in a single, combined Area and Terminal Control room.
Known as iTEC, it will form the new flight data processing system across our network. It’s already been introduced, entering limited operational service in early 2016 for upper airspace controlled from Prestwick.
It includes a range of tools to help reduce air traffic controller workload, increase airspace capacity and improve safety by automatically detecting potential aircraft conflicts ahead of time. It will enhance interoperability between control centres in Europe and will also make it possible for aircraft to optimise their routes as it is an enabler for FRA.
Part of a strategy to speed the deployment of new technology designed to harmonise air traffic controller input, iTEC is in service of our Any Controller, Any Workstation, Any Centre, Any Customer strategy.
The work we’re doing to install and introduce into service iTEC aligns with the SESAR programme to harmonise air traffic management across Europe.
SESAR, Single European Sky ATM Research programme, is now in deployment phase. Having gone through concept of operations, its various elements are now being rolled out ahead of entering normal service.
Through the A6 Alliance of ANSPs, alongside the A4 airlines and the SESAR-related Deployment Airport Operators Group (SDAG), we’re part of the SESAR Deployment Manager that is co-ordinating this phase for the first set of SESAR solutions to be in place across Europe by 2024. This will bring shorter flight times, increased predictability on arrivals and departures, fewer cancellations and delays, and a reduction in CO2 emissions in spite of increased traffic. It will also bring economic growth and employment and maintain Europe’s global leadership in air transport and aviation.
Much of the innovation you’ll have seen across this report; from TBS and Borealis and much more besides, falls within the overall SESAR programme. We look forward to posting further updates on progress and its benefits.
We’re building on our innovative DataLink trials that are successfully reducing longitudinal and lateral separation standards in the North Atlantic and delivering safety and environmental performance improvements.
Customer consultation on our next innovation, further reductions in these standards through the introduction of surveillance data, is underway. In airspace with no terrestrial surveillance, we’re proposing to use space-based ADS-B surveillance, alongside our existing satellite based communications and navigational tools, to provide controllers with new tools and processes to safely control traffic.
Expected in 2018, this proposal is expected to improve safety, save fuel and emissions and improve the predictability of North Atlantic operations. It will also offer some mitigation for airlines unable to meet key technical challenges of the NAT DataLink mandate
We are established as one of the leading commercial air navigation service providers through our corporate structure and business ethos. NATS operates in air traffic control markets both in the UK and abroad.
Our Airport Capacity Management (ACM) tool was instrumental in creating Heathrow’s first new early morning arrival runway slot in nearly 20 years.
Vietnam Airlines filled the gap, broadening still further the range of destinations served by the airport and choice of operators; benefiting the passenger experience, increasing revenues for both airport and airlines and, based upon the secondary trading value of airport slots at constrained airports like Heathrow, valuable assets for airlines.
ACM now means simulations which used to take several days to post a result now take seconds. By using these results together with data analysis, it supports effective decision-making about runway capacity, scheduling and planned infrastructure changes.
The tool can also be applied to a wide range of other airports to support measures to understand their individual operating challenges and to support measures to improve capacity.
While ACM is delivering benefits, the success of Time-Based Separation spurred NATS and Lockheed Martin to explore how advanced software could further help airports build resilience and create capacity in all weather conditions.
The Intelligent Approach suite of tools, based on a common, fully portable/compatible platform, is designed to help all airports do this at a fraction of the cost of adding taxiways and runways. It offers solutions around enhanced safe separation of aircraft (delivering greater consistency of spacing), improves operations in strong headwinds, fog or low visibility and can also assist controllers managing intersecting runways when it is safe to clear flights for departure as it analyses interacting aircraft movements.
The key capacity and congestion challenges facing this region are echoed in our experience of managing the ATM network over the UK. The air traffic network for the Middle-East is, effectively, the world’s aviation crossroads.
More flights and significant investment in airports has created more demand on the air traffic network, which is critical to serving present and future demand for air travel safely and efficiently.
We brought together the aviation industry from across the region for a symposium in Qatar in April to inform the debate on future development. Delegates from the RAF and LOCOG, which organised the London Olympics in 2012, were among those who shared their experience as Qatar prepares to host the World Cup in 2022.
The NATS team also commissioned research by Oxford Economics on the economic benefits to improved air traffic control.
Our teams are working with the Kuwaiti Directorate of Civil Aviation to oversee the installation of engineering equipment to support airport expansion. In Oman, we are supporting the Public Authority of Civil Aviation by carrying out the safety assurance at its new ATC centre. Here, and in the UAE, we also delivered engineering training contracts.
We opened our office in Singapore last year to enable us to support our clients both there and in Hong Kong, where a third runway is planned for Chep Lap Kok. Demand is growing for air travel in the region as prosperity rises and budget airlines expand to serve over half the global population. The experience we can share of decades of managing some of the world’s busiest airspace in the UK means we can offer practical support to help solve challenges across the air traffic management spectrum. As a result, we are working closely with colleagues in Indonesia and the Philippines and continue to build on more established relationships in Australia, Japan and India. In Thailand, too, we are in talks to advise on enhancing ATM infrastructure and optimising performance.
We completed our first year of successful service delivery at the biggest centralised operational Army airfield in the UK, Wattisham Flying Station, as part of Project Marshall.
Our work there is part of our joint venture with Thales, called AQUILA, to deliver the MOD programme to transform terminal air traffic management at military airfields. The contract is valued at around £1.5bn over the course of its 22-year-lifespan. It will modernise ATM at over 100 MOD locations, in the UK and overseas, including more than 60 airfields and ranges. From April 2016 we will also provide the ATC service at Middle Wallop and Netheravon as part of that same contract.
Air traffic movement increases ranged from six to ten per cent at the nine Spanish airports under the ATC management of FerroNATS, a company formed with Spanish infrastructure provider Ferrovial, in 2011. Alicante and Ibiza enjoyed good summer operations with reductions in delays and taxi times.
