When I had my initial Class 1 many years ago (it was at a CAA building just off Kingsway IIRC before FCL and the Medical Branch moved to Gatwick), in addition to the various test already mentioned, I (and presumably everyone else) had to have an EEG. I remember this particularly as, some days after the medical, I received an urgent phone call summoning me back to have another EEG. Whatever the problem, the second EEG resolved it. I was told the CAA required a satisfactory initial EEG as a baseline in the event of subsequent brain injury.
Is it still a requirement to have an EEG at the initial Class One examination?
