When is it safe to fly? Addressing medical conditions in pilots

Since World War I, the role of physicians who care for pilots has been to minimize the risks posed by the unique environment in airplanes and the demands of flying. Originally, that meant screening out those with any physical limitations that might affect their ability to fly such as vision or cardiac problems. Today, however, with the ability to better manage patients with multiple conditions, the physician's task is more nuanced and requires an estimation of risk based on the how well a pilot's condition can be managed and the type of flying he or she does. This article looks at how pilots are medically evaluated and how the standards for medical certification are evolving, allowing some pilots who have certain conditions to continue flying.
