Plain English Meaning
It is a special approach used at airports with two runways close together. One aircraft flies a path that is angled slightly off from its runway, while another flies straight in to the parallel runway. Both get vertical guidance down, and high-precision radar watches them to keep them safely apart. Near the bottom, the pilot on the angled approach sees the runway and turns slightly to line up and land.
