Ok..once I put the correct settings and everything into the ILS frequencies and what not, I click the LOC (localizer button) and then the plane will align with the runway and then I push the APP (approach) and once the plane captures the glideslope it will start to descend like normal. My approach speed was 150-160 and flaps were set to full but the aircraft points the nose down when approaching the runway instead of it beings the opposite. It also keeps saying don't sink don't sink (i think) and when it lands it lands level instead of on the back tires like ti should. It doesn't flare which that would be an autoland I assume. I was landing at a CAT III runway, so autoland should of worked, but the autoland indicator said no autoland. What is going on?  Any help would be nice.  Thanks
