How to become an Air Traffic Controller — your road, class by class

Air traffic controllers keep aircraft safely apart in the air and on the ground. In India the Airports Authority of India (AAI), a Mini Ratna public sector enterprise that manages civil aviation infrastructure and airspace, recruits them as Junior Executives (Air Traffic Control). [1]

A normal working day

• Talk to pilots by radio and give clearances for take-off, landing and routes.
• Watch radar and traffic, and keep safe distances between aircraft.
• Work in shifts — airports run day and night.

Hidden challenges

• You must reach ICAO English proficiency level 4 during training, or your services can be terminated. [1]
• A ₹7 lakh surety bond ties you to AAI until 3 years after training, and you can be posted anywhere in India. [1]
• Selection checks more than marks: a voice test, a psychoactive substances test, a psychological assessment and a medical. [1]

Who should not choose it

• You freeze under pressure — controllers decide in seconds.
• You dislike night shifts and rotating rosters.
• Your spoken English is weak and you will not work on it.

1. You are here Class 8 · Class 9

   English, Physics and Maths

   • You need spoken and written English at 10+2 level — English must be a subject in Class 10 or 12. [1]

   Doubt What does an air traffic controller do?

   Keeps aircraft safely apart in the air and on the ground. In India the Airports Authority of India manages airspace and recruits controllers as Junior Executives (ATC). [1]

   Next: Read the Routes list above.

   Doubt Is English important for air traffic control?

   Very. AAI asks for 10+2-level spoken and written English (English as a subject in Class 10 or 12), and you must reach ICAO English level 4 during training. [1]

   Next: Practise speaking English every day.

2. You are here Class 10

   Take PCM

   • The degree must include Physics and Mathematics, so take PCM in Class 11. [1]

   Stream / subjects: Science with Physics and Mathematics (PCM).

   Common mistakes

   • Dropping Maths or Physics — the B.Sc route needs both.

   Doubt Which stream do I need for air traffic control?

   Science with Physics and Mathematics, because AAI asks for a B.Sc with Physics and Mathematics, or an engineering degree with both in the course. [1]

   Next: Choose PCM in Class 11.

3. You are here Class 11 · Class 12

   Plan a B.Sc (PM) or B.Tech

   • Plan a full-time B.Sc with Physics and Mathematics, or a B.E. / B.Tech through JEE Main or your state CET. [1] [2]

   Exams that open here

   • JEE Main 2026 — Session 1: 21–30 Jan · Session 2: 2–9 Apr 2026 [2]

   Doubt Can I become an air traffic controller right after Class 12?

   No. AAI asks for a full-time regular B.Sc with Physics and Mathematics, or a B.E. / B.Tech in any discipline. [1]

   Next: Plan your degree first.

   Doubt Is a B.Sc enough for ATC, or do I need B.Tech?

   A full-time regular 3-year B.Sc with Physics and Mathematics is enough; an engineering degree in any branch also works if Physics and Maths were in a semester. [1]

   Next: Pick the degree you can do well in.

4. You are here In college

   Next: Join a regular college.

   Doubt Does any engineering branch work for ATC?

   Yes — any discipline, as long as Physics and Mathematics were subjects in any one semester. [1]

   Next: Keep the marksheet that shows those subjects.

5. You are here Graduated
