Medical reasons for permanent and temporary disqualification of Turkish civil aviation pilots.

The aim of this study was to identify diseases that result in permanent and temporary medical disqualification for civil aviation pilots and their changes over the years. A retrospective analysis was conducted on the medical examination records performed in Turkey from 2018 to 2022, in accordance with ICAO and EASA standards. The permanent disqualification rate was 1.3%, and the temporary disqualification rate was 6.6%. The most common reasons for permanent disqualification among pilots were circulatory system diseases (24%), mental and behavioral disorders (22.9%), and nervous system diseases (11.5%). The most common reasons for temporary disqualification among pilots were circulatory system diseases (17.9%), digestive system diseases (11.8%), and health problems related to COVID-19 infection (9.5%). The data obtained from this study may be useful in developing preventive medicine approaches to prevent medical disqualifications and in-flight medical incapacitation.
