Sudden inflight incapacitation in general aviation.

This study considered NTSB data and post-crash medical data received by the Medical Statistical Section of the Civil Aeromedical Institute (CAMI), Oklahoma City, OK from 1975-82, and other related literature to estimate the probability of incapacitation in general aviation. Data for the years studied indicate that approximately 3 accidents per 1,000 (15 per 1,000 fatal accidents) are known to result from the incapacitation of the pilot for all causes. Results suggest that the likelihood of incapacitation increases with age. The occurrence of incapacitation for obvious medical reasons is less than would be expected based on general population morbidity/mortality data; however, the need for continued vigilance in certification, and education regarding flying with known or suspected medical problems, is emphasized.
