The FAA designates reference waypoints for aircraft and air traffic control to use for navigation. These are known locations which are available on all FAA maps, charts, and electronic databases such as GPS. All reference points are designated with 5 letter names which can be pronounced as two syllable words. Examples: HILIS, FARES, WILON.
