KODIC - Kompetens, kapacitet och optimering i digital flygledningscentral

Remote Towers Services (RTSs) are one of several technological and operational solutions that the SESAR Programme is delivering to the ATM community for deployment. Over the last years, the Swedish ANSP Luftfartsverket (LFV) has been working on the deployment of the RTS concept as an alternative to traditional Air Traffic Service (ATS).
In 2015 and 2016 LFV and Swedavia conducted a joint feasibility study to analyze the impact of the transition from traditional tower ATS to RTS for five additional appointed airports in Sweden. The study confirmed that RTS is technically and operationally feasible, the level of risk is manageable, and that it is deemed financially advantageous to use RTS for these airports. In particular, the study identified several issues related to staff scheduling when multiple airports are operated from a single center.

The main research questions are: How to distribute the workload from several airports over several controller working positions?
How to assign a qualified controller at each position, respecting the constraints on the durations of controllers shifts, breaks and the necessity of maintaining ratings?

Within the project we develop a general optimization framework designed as a flexible tool for future staff planning. The model under development is discussed with operational experts to provide a picture on staffing constraints as close as possible to reality.
The results of this work help to evaluate efficiency of the RTC concept in general and give intuition for further deployment. Furthermore, the designed techniques and tools will be applied to other sets of airports being considered for remote operation.

CYBSEC (Pre-studies)- Security and Privacy of Air Traffic Communication (Säkerhet och Integritet för Kommunikation Flygtrafik)

A number of wireless technologies are used by air traffic communication systems during different flight phases. From a conceptual perspective, all of them are insecure as security was never part of their design. Airlines and airports increasingly become targets of cyber attacks. EASA’s new cybersecurity centre registers about 1000 attacks each month. With the widespread availability of cheap and powerful tools such as software-defined radios (SDR) and drones, the high-profile incidents, such as the case of hijacked emergency signals or alleged military exercises causing aircraft to vanish from European radar screens, became potentially feasible, which has been proven recently by hackers and the academic community.

Recent contributions from academic and hacking communities have exploited potential vulnerability of air traffic communication to demonstrate attacks on some of the currently used technologies. However, not all of these contributions have resonated widely within aviation circles. There exists an obvious mismatch between security research and the aviation community concerning their approaches to the problem of air traffic communications security.

Goals. Within the project we examine the security measures currently adopted in air traffic communication in Sweden, analyse technical characteristics of the wireless ATM communication technologies and examine the possibility of attacks and unauthorised usage. The pre-studies and the follow-up studies will build a bridge between the ATM and research communities in the field of wireless communication security. We will propose a set of potential countermeasures able to defend air traffic control systems and significantly improve the security of air traffic communication networks under the existing real-world constraints.
