Are there vision or hearing requirements for air traffic controllers?

Yes. Air traffic controllers must meet vision and hearing requirements because the job depends on clear perception of displays, radio calls, alarms, runway movements and written information.

Corrected vision may be acceptable: Vision requirements usually include adequate distant and near vision, with correction allowed in many cases. Glasses or contact lenses do not automatically prevent an ATC career if the corrected vision meets the required standard.

Colour perception is important because controllers may need to interpret radar labels, warning colours, light signals and visual information correctly. Significant colour vision deficiency can be a problem, depending on the authority and test result.

Hearing is normally assessed through an audiogram or equivalent test. Controllers must be able to understand speech clearly, including radio communication that may be fast, accented or affected by background noise.

The final decision is made through the required ATC medical assessment, often Class 3 or a national equivalent. Candidates with known vision or hearing issues should complete the medical process early.

A medical limitation is not always a rejection. Some controllers may work with glasses, contact lenses or other approved limitations if the authority accepts them and operational safety is not affected.

However, because ATC training is selective and expensive, candidates with known issues should complete the medical stage early. It is better to know the result before relocating, leaving a job or starting a long training process.

During the medical, be precise about previous diagnoses, hearing aids, glasses, contact lenses, surgery or medication. Complete information helps avoid delays and reduces the chance of a later certification problem.
