Definition
A neurological disorder characterized by recurrent seizures caused by sudden, abnormal electrical activity in the brain. A history of epilepsy is a disqualifying condition for FAA medical certification unless a special issuance authorization is granted.
Plain English
A brain condition that causes repeated seizures. Because a seizure in the cockpit could result in loss of control of the aircraft, pilots with epilepsy generally cannot hold a medical certificate without special FAA approval.
Context Anchor
Seen when reviewing medical conditions that may affect eligibility for an FAA medical certificate.
Derivation
From the Greek epilepsia, meaning 'a seizing upon' or 'attack' -- reflecting the sudden way a seizure takes hold of the body. The origin reinforces that the condition is defined by these episodes, not by the person's general health between them.
Why Pilots Care
Epilepsy is a disqualifying condition for standard FAA medical certification and requires a special issuance process with documented seizure-free periods.
Grounding Statement
The key aviation issue is sudden incapacitation: the pilot could become unable to safely fly the aircraft without warning.
Intuition Check
Epilepsy is not just feeling faint, being nervous, or having a one-time unusual episode. In this context, the concern is a medical tendency toward seizures that could suddenly impair a pilot.
Example Sentence 1
The applicant disclosed a history of epilepsy on the medical application, which triggered a special issuance review by the FAA.
Example Sentence 2
After five years without seizures and with neurologist documentation, the pilot became eligible to apply for a special issuance medical certificate.
