Just wanted to clear up some misunderstandings regarding confidentiality within a doctor-patient relationship. Breaching confidentiality isn't something we do lightly, but there are numerous situations where NOT doing so would be illegal; for example, doctors have a legal obligation to inform vehicle licensing authorities if someone develops a medical condition rendering them unsafe to drive - epilepsy, for example. In the case of pilots, the list of such conditions is much longer, and rightly so. Any doctor who suspected a pilot of being unsafe to fly and who failed to breach confidentiality and inform his employers as well as the relevant licensing and safety organisations would leave themselves open for criminal negligence proceedings.
