The investigation, made by LFV, after the radar disruptions that affected parts of Sweden’s air traffic on 4 November 2015, shows that the disruptions were due to radio emissions linked to a solar flare. This is the conclusion from the investigation conducted by LFV after the event.
On Wednesday 4 November 2015, at around 16:00 hours, air traffic control centres in Stockholm and Malmö noticed the first indication that LFV radar stations were not relaying the correct data to air traffic control. The cause was rapidly identified and measures taken.
“When the disturbance occurred, those of our air traffic controllers who were unable to use the information on their radar screens, changed over to a different way of managing the aircraft,” says Ulf Thibblin, Technical Director, LFV.
To LFV, safety is our main priority. If safety for different reasons, bad weather or technical disruptions, could not be guaranteed, the number of air traffic is being reduced.
In recent days, there has been discussions that the interference were not related to space weather, but that it instead was due to a cyber attack against Sweden.
“Early on in our investigation we had this as one of other hypothesis. But there was nothing in our radardata- or Internet traffic logs to support or confirm a possible cyber attack. Also, we had the relationship in time with space weather, plus there were a few more technical reasons which excluded a cyber attack, says Ulf Thibblin.”
After affected radar stations had been restarted, LFV’s air traffic controllers received correct radar presentation 45 minutes after the disruption had begun and after an additional 45 minutes there was full capacity in the airspace.
Over the past 17 years, LFV radar stations have only been affected by similar problems twice, in 1999 and 2003. The disturbances both then and now took place at sunset, when the angle of the sun goes – for the most part – directly into the radar stations.
According to experts, it is possible to predict a solar flare but not its consequences, for example radio emissions. As the disturbance is carried from the sun to the earth at the speed of light, it is also impossible to receive prior warning of an established outburst.
LFV’s radar stations around Sweden are continually upgraded and will remain in use. However now they will be supplemented with a new type of radar known as Wide Area Multilateration, WAM, which means the robustness will increase significantly.
In 2015 LFV carried out successful efforts to increase efficiency. This allowed Sweden’s route charge to be lowered for the fourth year in a row on 1 January 2016. The reduction was 4.6%.
“In 2015, LFV has managed to generate profits while helping lower the charges for en-route operations. This proves that our work with changes and increased efficiency has succeeded,” says LFV Director General Olle Sundin.
LFV’s turnover in 2015 was SEK 3.4 billion and the result after income and expenses was SEK 39 million. The large increase in turnover between 2014 and 2015 is explained by low interest rates, which have significantly increased the pension debt and thus the turnover.
The number of aircraft movements in Swedish airspace increased by just over 1%, totalling 712,000. The only year with more movements in the last decade was 2008. Overflight traffic, with no take-off or landing in Sweden, makes up around 40% of the total traffic.
2015 was also the year when LFV made history by introducing its Remote Tower Services. After ten years of development, the Remote Tower Centre in Sundsvall was opened on 21 April. Since then, traffic at Örnsköldsvik Airport has been handled from Sundsvall.
“LFV has made Swedish history with our Remote Tower Services, and we are now bringing our product to the rest of Sweden and the world,” says Olle Sundin. Next in line are Sundsvall Timrå Airport and Linköping City Airport.
In the past year, LFV established a Norwegian airline, LFV Norway A/S, in order to meet the Norwegian deregulation of local air traffic services.
LFV has delivered very reliably throughout the year. 99.9 per cent of all flights en route in Swedish airspace take place without any delays caused by the air navigation service.
In 2015 LFV published a drone map, a service which quickly became very popular among drone flyers. The drone map allows a person to use their phone to check their position in relation to the airports’ control zones.
Within the COOPANS alliance, where LFV is one of five partners, there were several upgrades to the air traffic control system TopSky to increase efficiency in air traffic control.

LFV received a SES Award for Remote Tower Services, the first operational approved remote tower service in the world, at World ATM Congress 2016 in Madrid this week.
– It is with great pride and joy that we recieve this award. Remote Tower Services will change the conditions for air traffic services. The award encourages us to continue our development towards a more efficient and smarter air traffic in Europe, says LFV’s Director General Mr Olle Sundin.
The number of aircraft movements in Swedish airspace increased by just over 1% in 2015, coming up to 712,000. During the 2000s, the only year with more movements was 2008. This information comes from LFV traffic statistics for last year.
“The statistics show that aviation is important for Sweden’s accessibility, both within the country and with the rest of the world,” says LFV’s Communications Director, Elisabeth Lindgren.
Of the three categories of domestic, international and overflights, the latter accounted for the largest increase in 2015 at just over 2%. International flights increased by 1.3% and domestic flights decreased by 1.5%. Overflight traffic represents more than 40% of the total volume of traffic and consists of traffic that does not start or land in Sweden.
Of course, there is a strong correlation between the increase in the number of movements and the fact that Stockholm Arlanda Airport breaks the passenger record of over 23 million passengers in 2015.
“The majority of overflights in Swedish airspace consist of traffic between Asia and Europe. Domestic movements are decreasing, while the number of passengers is increasing. This means each aircraft is fuller, which is also good for the environment,” says Elisabeth Lindgren.
Looking at developments during the year, air traffic decreased from January to October while it increased in the other months like-for-like in 2014. The biggest increase was in December, when traffic increased by just over 3%.
“Statistics from Eurocontrol for the EU are not ready yet for the whole year of 2015, but November figures suggest an increase of 1.5% for 2015 overall,” says Elisabeth Lindgren.

Every year LFV awards an incentive scholarship to a student or employee at Linköping University. In 2015 it was awarded to Åsa Svensson.
Last year Åsa Svensson worked on developing a method for collecting operative data with the help of eye tracking, meaning that eye movements are recorded and then analysed at different levels of detail.
“This is the first time that the incentive scholarship is given to a PhD student. Åsa’s work has contributed significantly to the development of an innovative method with great potential, so the scholarship is well deserved,” says Ulf Thibblin, Director, System and Development at LFV.
“It’s really interesting to work with LFV and there is great potential for developing the design of the work environment as well as training. We have worked with overflight traffic, arriving flights and the tower environment,” says Åsa.
LFV operates air traffic services at 23 airports and two control centres. LFV’s 800 air traffic controllers handle around 2,000 flights every day and are responsible for the safety and efficiency of each flight.
Advanced system support, including radar installations and air traffic controllers’ display screens, is required to maintain everyday operations. Many of LFV’s 120 engineers work in this area. LFV also conducts research and development into the future of air traffic management services. This is carried out in collaboration with the university as well as in several European cooperation Projects.
