Sounds like an 'autoland'. In the U.S. pilots are required to perform a
certain number of 'autolands' in order to remain current and be able to
land in conditions less than standard ILS CAT I minimums (i.e. landing
in fog). The plane is not designed to autoland itself smoothly, it is
designed to touch down within a specific spot on the runway and come to
a complete stop quickly. The software programmers were not very
interested in being smooth. BTW: In case anyone has any fantacies of
being able to land a 777 by pushing an 'autoland button', an 'auto
land' is actually much more difficult than just hand flying.
