Becoming an air traffic controller: DFS selection process, training and daily work

You listen in at the spot with your scanner as the tower brings the next aircraft onto the runway, and you think: I could do that too. In fact, the path to becoming an air traffic controller in Germany is clearly structured but demanding. If you want to become an air traffic controller, you generally apply to DFS Deutsche Flugsicherung, go through a multi-stage selection process at DLR in Hamburg and then learn in Langen near Frankfurt before moving, with real traffic, into a tower or a control center. This guide shows you requirements, process, training and daily life – and what you already bring as a spotter.

Becoming an air traffic controller: the short answer

You need an Abitur with an average of at least 2.7, very good English, fluent German and medical fitness under EU requirements. Then you apply online to DFS, pass online tests, two assessment appointments at the German Aerospace Center (DLR) in Hamburg and an aviation medical examination. Theory and simulator at the DFS campus in Langen follow, along with on-the-job training at a location in Germany. Only with all licenses and ratings do you work on your own responsibility.

Important in advance: at DFS you have only one application for controller training. If you fail, you can’t apply there again for this profession. That is the most important reason to take an honest look at the requirements profile before you click “Submit.”

Who directs air traffic in Germany

DFS is the federally owned company that controls air traffic over Germany. How the organization is structured and what it is responsible for is explained in detail in the article DFS Deutsche Flugsicherung explained. For choosing a career, the basic principle is enough: DFS employs controllers in four control centers and in the towers of the international airports – 15 towers according to its own figures. At many smaller airfields, other providers handle aerodrome control; separate hiring routes apply there.

Part of the upper airspace over northwestern Germany is looked after not by DFS but by the Maastricht control center of the European organization Eurocontrol – more on that in Eurocontrol explained. And if you look across the borders: in Austria and Switzerland, Austro Control and Skyguide are responsible; the differences are described in Air traffic control in Austria and Switzerland.

Tower or center: two different jobs

Training splits early into two directions that differ markedly in daily life.

• Tower: Here you direct traffic at and around the airport. Aerodrome controllers are responsible for runways, ground controllers for movements on the ground. VFR pilots also contact the tower. You work looking outside, but of course also with radar and ground situation displays.
• Center: In the control center you guide aircraft in the airspace without ever seeing them. Work is typically done in a two-person team: the radar controller talks to the cockpits, the coordination controller coordinates with neighboring sectors, for example when routings change. Depending on the location, the center also includes approach control, which sequences aircraft onto final approach.

Which radio position is responsible for what – delivery, ground, tower, approach, center – is shown in the guide Delivery, ground, tower, approach, center. If you regularly listen to ATC radio, you already know this chain from listening.

Criterion	Tower	Center
Workplace	Tower at an international airport	Control center (Bremen, Langen, Karlsruhe, Munich)
Responsibility	Runways, taxiways, the airport’s immediate area	En-route and approach airspace
Picture of the situation	View outside plus radar and ground situation	Radar display, no visual contact
Typical way of working	Aerodrome and ground controller at separate positions	Radar and coordination controller as a team
Typical situations	Runway occupancy, taxiing traffic, change of runway direction in use	Separation, sector handovers, weather deviations

The requirements in detail

DFS describes its requirements profile quite precisely. As of October 2026, the following applies:

• School: general higher education entrance qualification (Abitur) with an average of 2.7 or better. You can apply while you are still working toward the Abitur; then your latest report cards are enough at first.
• Language: English at Abitur level or at least a C1 certificate, fluent German. Without a German Abitur you need a C1 certificate in German.
• Vetting: You consent to a reliability and security check.
• Flexibility: Shift work and a later posting anywhere in Germany have to be fine with you.
• International applicants: For qualifications from abroad, official recognition of equivalence is required; outside the EU you also need a permanent residence permit with work authorization.

DFS names no fixed age limit on its requirements page. DFS recommends applying about a year before your desired start; there is no application deadline for the classic training, and courses start several times a year.

Medical fitness

The health requirements are set Europe-wide in Regulation (EU) 2015/340, which also defines licenses and training for air traffic controllers. DFS particularly emphasizes: full eyesight and flawless color vision, where glasses or contact lenses are allowed up to a certain diopter limit, unrestricted hearing and no chronic illnesses that rule out fitness. When in doubt, for example with diabetes, DFS advises asking an aviation medical examiner beforehand. That is also good advice before you start your only selection process.

The selection process step by step

The process has several stages. The two on-site appointments take place at DLR in Hamburg, which also carries out the aptitude assessments for pilots – how that works there is described in the article DLR test and pilot selection.

For the two Hamburg appointments, you should plan several days in total, according to DFS. Supporting offerings include online taster days and the annual Recruiting Day at the campus in Langen. According to DFS itself, it doesn’t offer school internships for this profession.

How to prepare sensibly

DFS recommends preparing with the information and practice material provided and advises against commercial preparation courses. What else you can do without spending money:

• Brush up your English, especially listening comprehension and free speaking. Radio in commercial aviation is predominantly in English – why, and where German is still allowed, is covered in English or German on the radio.
• Practice mental arithmetic and estimating, without a calculator and under time pressure.
• Train spatial thinking: map reading, headings, picturing the movements of several objects.
• Sleep well before the test days. Concentration and multitasking exercises are sensitive to fatigue.

The training: Langen, simulator, real traffic

DFS divides the classic training into three phases. The details come from the DFS careers page and may vary depending on course and area of assignment.

Phase	Location	Duration according to DFS	Content
Basic training	DFS campus Langen	approx. 5 months	Navigation, aviation law, aircraft type knowledge, meteorology, aviation English, radiotelephony procedures, first simulations
Simulator training	DFS campus Langen	approx. 8–12 months	Training on realistic simulators, focus on tower or center
On-the-job training	Tower or control center in Germany	approx. 12–24 months	Working in live traffic under guidance, gradually more responsibility
Takeover	Place of assignment	–	Working as a fully qualified controller after obtaining all licenses

In basic training you learn the fundamentals that many spotters already know in part: airspace structure (see Airspace classes A to G), weather, aircraft types and the language of radio. The fixed phraseology that makes everything unambiguous on the radio is a field of study of its own – Radiotelephony phraseology explained gives you an introduction, and the ICAO spelling alphabet comes on top.

In the simulator phase things get practical. You practice scenarios that closely follow real procedures: separation between arrivals including wake turbulence spacing, holding patterns at bottlenecks (more in Holding explained), emergencies and special situations. This is where it shows whether what was measured in the test also works under realistic load.

In on-the-job training you move to your location and talk to real cockpits – always with an instructor at your side who can intervene. At the end come the exams you need for the license and the rating for your specific workplace.

Licenses and ratings under EU law

Regulation (EU) 2015/340 distinguishes between the student air traffic controller license and the actual air traffic controller license. In addition come ratings for the area of activity – such as aerodrome control, approach control or area control, in some cases with a separate variant for work with radar display – and an endorsement for the specific control unit where you work. This endorsement is valid only for a limited time and has to be regularly confirmed through the unit’s competence scheme. English proficiency is also reassessed at fixed intervals; for the minimum level 4, every three years. So learning never quite stops in this profession.

Alternative: becoming a controller with a degree

Instead of the classic training, DFS offers a dual degree program. You first study three semesters taught in English in Air Traffic Management at Worms University of Applied Sciences – business administration, airport management, aviation analytics – with practical phases in Langen. After that come controller training in Langen and on-the-job training, while you write your bachelor’s thesis in parallel. At the end you have a Bachelor of Science and the controller license. DFS describes the model as three semesters of study plus roughly 2.5 to 3.5 years of training and covers the university’s semester fees. It starts in either March or October; unlike the classic training, fixed application deadlines apply, which you’ll find on DFS’s careers page.

Money and conditions

For pay, DFS cites these orders of magnitude on its careers page (as of October 2026): during the time at the academy there is around 1,450 euros a month plus a 400-euro housing allowance. From on-the-job training on, the salary rises depending on progress, area of assignment and location to about 5,000 euros gross a month, with allowances for shift, Sunday and holiday work on top. What trained controllers earn later depends on the collective agreement, location and experience – you only get reliable figures directly from the employer.

Among the conditions, DFS lists, among others, 13.1 monthly salaries and 32 vacation days. Keep in mind, though: these figures apply to the company in general and can change with every collective bargaining round.

Daily work

Work is done in early, day, late and night shifts, including on weekends and holidays. DFS draws up the duty rosters well in advance, and swapping shifts among colleagues is possible. Because radio work demands high concentration, breaks are fixed in the schedule: according to DFS there is, as a rule, a break of at least 30 minutes after two hours at the latest. A shift typically starts with a briefing on procedure changes, safety-relevant events and the traffic situation, and every relief involves a short handover at the workstation.

In the center, daily life is strongly shaped by traffic flow: sectors hand aircraft over to each other, thunderstorm cells force diversions, and at peak times the inbound flow to the big hubs like Frankfurt Airport or Munich Airport is sequenced. In the tower, a lot revolves around runway occupancy, taxiways and the change of runway direction in use when the wind shifts. If you want to know why delays occur despite all the planning, you’ll find background in Why flights are delayed and Airport slots.

And when something goes wrong? For stressful events, DFS has a program for stress management after critical incidents, with confidential conversations among colleagues. Emergencies such as a mayday call or an emergency squawk are part of training – what happens on the radio in such cases you can read in Mayday and pan-pan and Squawk codes 7500, 7600 and 7700.

What spotters bring – and what they don’t

As a spotter you have some real advantages: you recognize aircraft types, know airline callsigns, understand runway directions in use and may already have listened to ATC radio for hours – for example via web streams as explained in Listening to ATC online. What is allowed is covered in Is listening to ATC radio allowed?. This prior knowledge eases the theory phase and helps in the interview to make your motivation credible.

Honestly, though, it replaces nothing of what counts in the selection process: spatial thinking, memory, resilience and English are measured independently of your hobby. Enthusiasm is a head start, not a ticket. If you want to dig deeper into the background of the profession, you’ll find an interesting perspective in the history of air traffic control.

If controller training doesn’t fit, there are related jobs at the pulse of flight operations: apron control, which is often organized by the airport operator, the flight dispatcher or of course the cockpit – the various paths there are described in Becoming a pilot.
