One of today's AAIB reports contains a report about a helicopter pilot who had a history of migraine that was apparently not disclosed at his medical renewals.
It refers to the need to be "headache free and off medication for at least two months". Is this the requirement for a Class 2 initial medical as well as a renewal? I do not take preventative medication, and I do think mine are caused by environmental factors (eg dehydration) - which I think I have improved control over compared to recent years. Is it still likely to be a concern ?
