DESCRIBING A LIGHT'S CHARACTERISTICS

THREE FACTORS ARE USED TO DESCRIBE A LIGHT'S CHARACTERISTICS:

1) LIGHT RHYTHM

  • LIGHTED AIDS TO NAVIGATION ARE EITHER "FIXED" (CONTINUOUSLY ON) OR GENERALLY EXHIBIT RHYTHMS SUCH AS: "FLASHING", "OCCULTING", "ISOPHASE", ETC. (SEE NEXT CHART)

2) LIGHT PERIOD

  • FOR OTHER THAN "FIXED" LIGHTS, THE TIME IN SECONDS DURING WHICH THE PATTERN OF FLASHES IS REGULARLY REPEATED

3) LIGHT (LENS) COLOR

  • RED AND GREEN (HAVE LATERAL SIGNIFICANCE)
  • WHITE AND YELLOW (HAVE NO LATERAL SIGNIFICANCE)

FOR EXAMPLE: A LIGHT WITH PUBLISHED CHARACTERISTICS OF "Fl G 6s"

WOULD HAVE A FLASHING LIGHT RHYTHM, GREEN LENS COLOR,

ONE FLASH PER PERIOD, AND A PERIOD OF SIX SECONDS.
