How do air traffic controllers keep their licence current?

Air traffic controllers keep their licence current by maintaining medical fitness, language validity, operational competence and the endorsements required for the unit or sector they control.

Currency requirements: A controller may hold an ATC licence but still need a valid rating and unit endorsement to work a specific position. For example, being licensed for tower control does not automatically qualify someone to work an approach sector or a different airport.

Currency is maintained through regular operational work, local competence checks, continuation training and refresher training. These checks can cover procedures, equipment changes, abnormal situations, emergency handling, phraseology and human-factors topics.

The medical certificate or medical clearance must also remain valid. If the medical expires or is suspended, the controller normally cannot work operational duties.

Exact currency rules are set by the authority and air navigation service provider, so controllers must follow their local unit competence scheme.

If a controller has not worked a position for a certain period, the unit may require refresher training before they return. This protects both the controller and the operation because local procedures can change quickly.

Licence currency is therefore a mix of paperwork and real competence. A valid document is necessary, but it must be backed by current skill on the actual operational position.

Equipment changes are another reason currency matters. A new surveillance display, electronic flight strip system or runway procedure can require briefing or training before the controller uses it operationally.
