Certificate basis

• ICAO Annex 14, Volume I

Description/Properties

• beacon emits repeatedly series of four flashes lasting 0.5 to 2 ms within 0.8 s
• each series is separated from the next one by time interval of 1.2 s
• three levels of brightness (100%, 10%, 3%)
• automatic control of the brightness level of the flash in dependance to ambient light intensity using the photocell prevents from dazzling the pilot and saves energy at the same time
• low power consumption
• small size allows it is placement close to the heliport without risk of creating obstacles
• optional heating resistor
