If he'd of informed the examiner earlier and handed over control then the outcome may well have been different, I barfed an hour into my CPL/ME, just after the navex and a few circuits somewhere, we were climbing to go complete stalls, eng failure, rapid descent etc when I felt the colour drain and cold sweats.
I said 'you have control Im not feeling to good' 5mins and half a bag later we were doing the bits mentioned earlier and 50mins later informed of a pass.
