If everything was OK and he was flying on AP, he had at least CAT 3 SINGLE on the FMA.
And yet... Can we said that he was doing a CAT II approach without autolanding, where the 80 ft apply?
If he exceeded the limitation (CAT 1 displayed) and the QAR betrayed him disconnecting below 160 ft then he is screwed.
If CAT 1 was not displayed, then he did not exceed a limitation, as such. 80 ft could be taken as the limit, probably.
