Did a Cat 1 practice auto land at night/VMC(B767) into Per 21 about 5 mths ago.Wrote up as unsatisfactory,as had to disconnect on roll out about 90kts as the a/c veered to the side of the runway(Rollout annunciated).No known a/c defect and ATC said no a/c or traffic infrigments.
.....exactly why cat 2 and below have bigger protection margins...........still beats a ditching though.
