Helideck status light system
Visual warning system for helicopters, automatically initiated at
the appropriate hazard level (e.g. impending gas release) as well
as being capable of manual activation by the HLO.
CAA Paper 2008/01 provides a specification for a status light
system which is summarised below:
• Status light system should be visible from all approach directions, i.e.
360° in azimuth.
• The effective intensity should be a minimum of 700 cd between 2° and
10° above the horizontal and at least 176 cd at all other angles of
elevation.
• Manual dimming to an intensity not exceeding 60 cd while the helicopter
is landed on the helideck, if the system is active.
• The colour of the status light(s) should be red as defined in ICAO Annex
14 Volume 1 Appendix 1.
• The light system should flash at a rate of 120 flashes per minute.
• The light system should be automatically integrated with platform safety
systems.
• Facilities should be provided for the HLO to manually switch on the system
and/or override automatic activation of the system.
