This was an augmented flight.  I had the 3rd break; and was woken up 45 minutes prior to landing.  When I returned to the cockpit; I was informed that we would be doing a Cat III autoland due to fog and reported visibility of 500 meters.  All 3 pilots reviewed the Cat III autoland portion of the QRH prior to conducting the approach briefing.  The Captain armed the approach mode and engaged all three autopilots per SOP.  We heard the audible 'click' associated with the bus transfers.  All call outs were SOP; until the 500 foot call.  The 500 foot call was made; but we did not notice that the Autoland Status Annunciator (ASA) was blank; nor did the Pilot Flying (PF) announce 'Land 3.'  All other call outs were standard.  The approach lights came into view at about 150 feet; and the runway environment at about 100 feet.  At some point; I believe about the time I made the 'approaching alert height' call out; the Captain said we did not have a 'Land 3' displayed.  At about 50 feet; the relief pilot stated that 'Flare' was not displayed.  At that point the Captain disconnected the autopilot and hand flew the landing.  The aircraft floated due to a slight balloon in the flare; at which time the relief pilot said we needed to go-around.  The airplane touched down within a few seconds and the remainder of the landing; rollout; and taxi were normal.  Once at the gate; we made a maintenance write-up of the autoland system; as well as debriefed the mechanic.  We clearly missed verifying the Land 3 annunciation; which should have been displayed at 1;500 feet.  We also did not verify its presence prior to 500 feet; nor did we catch it at the 500 feet call.  Thus; our first indication that something was wrong was when the Captain said we did not have a 'Land 3.' We should have initiated a missed approach at this point.  Instead; it took us several seconds to process what was happening.  The first one to realize we should be going around was the relief pilot.  By that time the auto flight was off; the runway environment in sight; and the airplane was within a second or two of touchdown.
We were conducting a Cat 3 approach with weather at 500 meters RVR. The approach was briefed including the QRH pages. When we were cleared for the approach; the captain armed APP and engaged all 3 autopilots. We all heard the click over of the electrical isolation. Looking back on it I don't believe we got the automated 2;500-foot call but we were busy with the controllers at this time. At about 1;000 feet I realized that the flight directors did not disappear. I tried to figure out what was wrong and realized we didn't have a flare or rollout armed. I remembered in the past we said 'land 3 flare and rollout armed' and I was trying to remember if that was still supposed to happen or if since we didn't say it anymore did that mean the aircraft was supposed to do something different. The captain missed the Land 3 at 500 feet and was checking the Autoland Status Annunciator. I said we didn't have a flare and the captain saw the runway and clicked off the autopilot. The aircraft floated and it was at this point I said we needed to go around. Within a second the captain had us on the runway and stopped in a timely manner. We made a log entry and talked to the mechanic. Many factors led to this. We were tired; talking to controllers we didn't understand; I had gotten food poisoning from crew meal chicken and was not at 100%; many callout changes and procedure changes and we missed 1;500-foot indications and 500 foot call outs.
B767 First Officers describe a CAT III approach during which LAND III does not appear in the Autoland Status Annunciator (ASA) descending below 1;500 feet and is not detected. Below 400 feet Flare and Roll out does not appear in the ASA and is not detected. Approaching minimums the Captain detects the lack of a Land III indication and disconnects the autopilot to land manually.
