Narrative:

During real CAT III approach; aural warning sounded for 'too low flaps' at approximately 150 ft. Go around accomplished and normal gear and flap retraction occurred. We were vectored for another approach and ensured that the flaps were set into the detents smartly. Below 200 ft the same aural warning occurred. With the approach lights in sight and the runway in view we continued with the approach to an uneventful landing.
