Certification and TIA
Transient Ischaemic Attack or (TIA), and the related condition of Amaurosis Fugax (temporary loss of vision in an eye due to a restriction in the blood supply to the eye) are normally disqualifying conditions, however, each case is individually assessed for the risk of recurrence. Medical certification, initially with a restriction to operations with a safety pilot or multi crew operations, may be possible after a period without any recurrence of symptoms.
Stroke, with only very rare exceptions, is permanently disqualifying.
