Nervous system Flying or controlling aircraft is complex and requires a well-integrated nervous system and the ability to solve problems rapidly. Disorders of the central nervous system can be a potent source of occult incapacitation. Lapses of consciousness or memory in the aviation environment can be fatal. The following conditions must be reported. Syncope A licence holder who suffers unexplained loss of consciousness, whatever the cause.
Seizure disorders The occurrence of single or multiple seizures.
Licence holders who suffer a significant head injury, particularly if it is associated with unconsciousness or post-traumatic amnesia. Following any severe head injury, the risk of cognitive impairment or late seizure is increased. Sleep disorders Licence holders who suffer from sleep disorders of any type, including narcolepsy and sleep apnea. Any condition that interferes even temporarily with balance or coordination must be investigated and reported. Any condition affecting coordination and muscular control in a licence holder must be reported.
