Air Traffic Control Aviation FAQ

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

1. Where it happens: At a specific tower, approach unit, area control centre or sector, depending on the future role.
2. Who supervises: A qualified instructor or authorised controller monitors the trainee while skills are built in the live operational environment.
3. End goal: The trainee must demonstrate safe, consistent performance before receiving the relevant unit endorsement or local validation.

OJT length varies widely by country, unit complexity, traffic level and individual progress.
