Invisible guardians of the sky: How air traffic controllers work

November 14, 2024
A typical action movie scene about airplanes: the pilot desperately tries to control a rebellious aircraft, while air traffic control specialists issue instructions, searching for ways to safely land.

It is these specialists who monitor the skies around the clock, and their decisions sometimes determine the lives of thousands of people — within the airspace controlled by an air traffic controller, there can be up to 20 planes at once, each with over 100 passengers on board.

We invite you to learn more about this profession, as explained by Edgaras Steckis, a lecturer at the VILNIUS TECH Antanas Gustaitis Aviation Institute (AGAI).

Constantly monitoring the sky

“The work of air traffic controllers starts from the ground, with the majority of responsibility falling on their shoulders when the aircraft is on the runway — the key here is to prevent any collisions. That’s why air traffic controllers often say: ‘Our eyes are watching your flight.’ And this monitoring happens 24/7, every day. They have to work on birthdays, during Christmas, and on New Year’s Eve,” says Steckis.

Currently, there are 92 air traffic controllers working in Lithuania. About 10 people work at the Palanga, Siauliai, and Kaunas airports, more than 20 at Vilnius Airport, and over 30 people at the Regional Center, which manages transit traffic over Lithuania.

Not a job for everyone

Air traffic controllers must be in good physical and psychological condition to carefully track the aircraft's position in the airspace — although it may seem boundless to the average person, aviation airspace is divided into many sections that are monitored by the specialists. Moreover, the job requires logical thinking, the ability to orient oneself in 3D space, and most importantly, the ability to quickly respond to a developing situation and choose the best solution.

“Every day is filled with situations where the air traffic controller prevents collisions between aircraft, because this is the main task and function of their job. Often, pilots on the plane are unaware of such situations because controllers work with internal restrictions and standards that are understood in the workplace. This is normal because everyone is doing their part,” explains Steckis.

Dr. Anrieta Dudoit, a VILNIUS TECH AGAI alumna and air traffic controller, describes her work as constantly changing and requiring ongoing learning. "Aviation is a dynamic, evolving, and multifaceted science, so to understand certain things, processes, and situations — especially their deeper meaning and interconnections — one must constantly study, delve deeper, and keep learning. I can confidently say that working in aviation requires continuous knowledge and skill maintenance — not only for air traffic controllers and pilots but also in other related fields, such as air navigation service provider maintenance,” she says.

Interdisciplinarity in practice: how Electronics and Medical Engineering students developed a Human motion analysis system
Modern engineering solutions are increasingly created through collaboration between specialists from different fields. The university environment provides an opportunity to combine diverse competencies and develop solutions that would be difficult to achieve within the boundaries of a single discipline. Such collaboration was also at the heart of a bachelor’s thesis project in which VILNIUS TECH students Laura Venckutė (Faculty of Electronics) and Abderrazak El Aamrani (Faculty of Mechanics) combined expertise in electronics and medical engineering to develop a human motion recognition and evaluation system. From an Idea to Interdisciplinary Collaboration At the beginning of the project, students from the Medical Engineering and Electronics Engineering study programmes sought to address a problem relevant to both sports and rehabilitation: the lack of accessible systems capable of automatically evaluating human movements and providing immediate feedback. As the project authors point out, incorrect movements can reduce training effectiveness and increase the risk of injuries during rehabilitation, sports activities, or everyday tasks. For this reason, they decided to look for a technological solution that could help objectively assess movement quality. The idea emerged from previous projects and experience gained during their studies, while an important catalyst was the opportunity for collaboration proposed by their supervisors. From the outset, it was clear that the project would require expertise from different fields, as motion analysis involves not only developing a technical system but also defining meaningful criteria for evaluating human movement. [caption id="attachment_120707" align="alignnone" width="2048"] Electronics and Medical Engineering students developed a Human motion analysis system[/caption] The students brought different, yet closely interconnected and complementary competencies to the project. The Electronics Engineering student was responsible for computer vision, embedded systems, and system integration, while the Medical Engineering student contributed expertise in biomechanics and human movement assessment. Although responsibilities were divided according to individual areas of expertise, key decisions were made collaboratively. From the Initial Concept to a Functional System In the early stages, the team planned to develop a system capable of analysing a broader range of movement patterns and performing more advanced analytical functions. However, as the project progressed, technical limitations, available hardware resources, and the scope of the bachelor’s thesis had to be taken into account. As a result, some ideas had to be abandoned. According to the team members, no major disagreements arose during the project. Decisions were made by discussing possible alternatives, evaluating how well they aligned with the project objectives, and, whenever possible, testing different approaches in practice. When technical and medical requirements conflicted, the team sought solutions that best balanced project goals and implementation constraints. The final outcome of the project is a human motion recognition and feedback system based on a pose estimation algorithm designed for basketball shooting analysis. The system detects a person in real time, estimates body posture, evaluates shooting technique according to biomechanical criteria, and subsequently provides feedback to the user. The Value of Interdisciplinarity and Future Opportunities During testing, the system performed better than expected. It successfully analysed the movements of users of different heights and maintained reliable performance at distances of up to 12 metres. According to the students, not only did the technical results exceed expectations, but the collaboration process itself also proved highly successful. In their view, such a project could theoretically be completed by a specialist from a single field. In practice, however, this would be difficult and inefficient. The project required both expertise in electronics and an understanding of human movement analysis. Without competencies from both fields, considerably more time would have been needed for learning unfamiliar topics and identifying appropriate solutions. Looking ahead, the students see opportunities to further develop the project by improving system stability, optimising resource usage, expanding the range of supported movement patterns, and increasing motion recognition accuracy. Although they are not yet certain whether they will continue working in this specific area, they hope to further deepen their expertise in related fields of technology and engineering. Supervisors’ Insights: Interdisciplinarity as a Foundation of Future Engineering The thesis supervisors emphasise that the nature of the project itself required collaboration across disciplines. However, the greatest value of the project lies not only in the technical solution that was developed, but also in the students’ ability to work together effectively. Professor Kristina Daunoravičienė, lecturer in the Medical Engineering study programme, notes that developing a human posture recognition and evaluation system requires both an understanding of human movement and biomechanics, as well as the ability to create a technical system capable of collecting, processing, and presenting information to the user. „The need for different knowledge and competencies made this topic an excellent platform for collaboration between Medical Engineering and Electronics Engineering students. Such projects foster not only technical solutions but also the ability to understand the logic, limitations, and priorities of other disciplines,“ says Prof. Dr Kristina Daunoravičienė. Although the students were initially unfamiliar with one another and came from different engineering backgrounds, a shared goal quickly became the foundation of successful cooperation. According to the supervisor, Medical Engineering contributed the perspective of human movement assessment and result interpretation, while Electronics Engineering provided expertise in system architecture, prototyping, and optimisation. According to Prof. Dr K. Daunoravičienė, the most important outcome of the project is not only the developed prototype and its comparison with the Xsens motion analysis system: „Equally important are the competencies of collaboration, communication, trust, initiative, and the ability to learn from one another. These are the qualities that allow good ideas to become real, functioning solutions.“ Associate Professor Dr Vytautas Abromavičius of the Faculty of Electronics also points out that in the era of artificial intelligence, technical expertise alone is no longer sufficient. Clear communication, the ability to understand specialists from different fields, and working together towards a common goal are becoming increasingly important. „This bachelor’s thesis demonstrated that our students communicated exceptionally well and were able to explain specialised professional terminology in a simple and understandable way. This mutual understanding enabled them to effectively combine knowledge from different disciplines and achieve an excellent result,“ says Assoc. Prof. Dr Vytautas Abromavičius. According to him, the need for interdisciplinary projects in modern engineering continues to grow. Every real-world product developed for the market consists of multiple interconnected components; therefore, a broader understanding of the problem leads to better product applicability and a more complete final outcome.
