In aviation, a waypoint is a predetermined geographical position that is defined in terms of latitude/longitude coordinates (altitude is ignored). Waypoints may be a simple named point in space or may be associated with existing navigational aids, intersections, or fixes.
Waypoints used in aviation are given five-letter names. These names are meant to be pronounceable or have a mnemonic value, so that they may easily be conveyed by voice. In some cases the names correspond to a notable feature or landmark in the area (for example, a waypoint near Newton, Iowa has the name "MATAG"; Newton was the birthplace of the appliance manufacturer Maytag).
