Training
Complete the college-based training
If you pass the assessment centre, you will begin the medical and security clearance processes immediately, with employment start dates beginning from March 2026. After a short induction period at our Corporate and Technical Centre in Hampshire, you will attend one of our initial training organisations to embark on your journey towards gaining a Student Air Traffic Control licence.
The length of college-based training varies depending on a host of factors, including the specialism you take and how quickly you can complete different phases. Most college-based training is completed within a year to eighteen months and includes a combination of practical and theory based sessions.
Complete the operational training
Once you have gained your Student Air Traffic Control licence, you will be posted to an operational unit where your hands-on training continues until you validate and are issued your full Air Traffic Controller licence.
Please remember that Air Traffic Controllers are mobile grades, which means that you may be required to work anywhere in the UK and ultimately this will be determined by the needs of the Company.
Congratulations!
Now you are ready to play your critical part in advancing aviation and keeping the skies safe!
