What is on-the-job training for air traffic controllers?

On-the-job training, often shortened to OJT, is the operational training phase where an air traffic control trainee applies classroom and simulator learning at a real ATC unit under supervision.

Supervised live traffic: OJT takes place at the tower, approach unit, area control centre or sector where the trainee is expected to qualify. The trainee works with live traffic while an authorised instructor or qualified controller monitors, coaches and can take over if needed.

The purpose is to build safe, consistent performance in the real local environment. That includes applying procedures, managing workload, communicating clearly, coordinating with other positions and making correct separation decisions.

OJT ends when the trainee demonstrates the required competence for the position and passes the local assessment. The result is usually a unit endorsement, local validation or equivalent approval.

The length of OJT varies widely. A quiet tower may take less time than a complex approach or area sector with high traffic levels.

OJT can be demanding because the trainee is no longer working with simulated traffic only. Real traffic, weather, coordination, runway changes and unexpected events all become part of the learning environment.

Progress is usually reviewed against defined performance objectives. If a trainee struggles, the unit may add extra training, change the plan or stop training if safe independent performance is not achieved.

Good OJT is structured. The trainee should know the training objectives, receive clear debriefs and see measurable progress rather than simply spending hours plugged in beside an instructor.
