Air Traffic Control Aviation FAQ

Aspiring controllers must hold an air traffic controller licence issued by the national aviation authority in line with ICAO Annex 1. To obtain it, candidates complete:

1. Approved initial training at an ATC academy, followed by on‑the‑job instruction at a unit.
2. Operational ratings (Tower, Approach or Area) that are endorsed on the licence after passing practical assessments.
3. A Class 3 (or national equivalent) medical certificate is renewed regularly.
4. ICAO English Level 4 or higher demonstrated in a certified language test.

Region‑specific labels differ, but the structure is similar. For example, the FAA Control Tower Operator (CTO) Certificate or EASA Student ATCO Licence progressing to a Unit Endorsement both satisfy the ICAO licence requirement once all components above are met.
