A landmark beacon is installed in order to indicate any specific point by means of light in flashing sequence or the Morse codes.
a) Flashing lights:12~100 white flashes in a minute.
b) Morse Code:6~8 words of the international Morse code in a minute. Each dot is emitted for 1~0.15 second. White or red light with a vertical distribution from horizon to 45 °upward is placed when collocated with an airway beacon.
