Medical requirements for obtaining and maintaining a licence
What are the visual requirements for commercial pilots?
Can a colour blind person have either a private pilot, a commercial pilot or an air traffic controller licence according to the ICAO regulations?
220.127.116.11.1 An applicant who has undergone coronary by-pass grafting or angioplasty (with or without stenting) or other cardiac intervention or who has a history of myocardial infarction or who suffers from any other potentially incapacitating cardiac condition shall be assessed as unfit unless the applicant's cardiac condition has been investigated and evaluated in accordance with best medical practice and is assessed not likely to interfere with the safe exercise of the applicant's licence or rating privileges.
18.104.22.168 Applicants with diseases of the blood and/or the lymphatic system shall be assessed as unfit, unless adequately investigated and their condition found unlikely to interfere with the safe exercise of their licence and rating privileges. Note. — Sickle cell trait and other haemoglobinopathic traits are usually compatible with fit assessment.
However, since the decision will be taken by the Aviation Medicine Department of the Licensing Authority in the State of application, any question referring to an individual case should be addressed to the Chief Medical Officer of the national Licensing Authority.
