Plain English Meaning

A GPS approach that tells you where to fly side-to-side toward the runway, but does not tell you how to descend. You handle the descent yourself using the altitudes printed on the chart.

Full Definition

A non-precision GPS-based instrument approach that provides lateral (left/right) course guidance to a runway, but no vertical guidance. The pilot flies the lateral track shown by the GPS and steps down through published minimum altitudes until reaching the Minimum Descent Altitude (MDA), where the runway environment must be in sight to continue to land.
