TRANBERG Helideck Status Light System


The TEF9980 Status lights is designed to fulfil the latest requirements of CAA UK CAP 437, as well as operator’s needs for products that are cost-effective, reliable, requiring no maintenance and applicable for use in all environments. The TEF 9968 Status light is available as a main light and a repeater light. Both versions are fully monitored, which eliminates need of redundancy light units. In combination with Tranberg control system the lights can be set up for automatic test intervals, timeouts for both dim level and on and diagnostics.

Purpose of Status Light

A visual warning system should be installed if a condition can exist on an installation which may be hazardous for the helicopter or its occupants. The system (Status Lights) should be a
flashing red light (or lights), visible to the pilot from any direction of approach and on any landing heading. The aeronautical meaning of a flashing red light is either “do not land, aerodrome
not available for landing” or “move clear of landing area”.
The system should be automatically initiated at the appropriate hazard level (e.g. impending gas release) as well as being capable of manual activation by the HLO.

Number and location of light units

The number and location of light units should be considered in cooperation with the helideck operator. Ref. CAA Paper 2008/01, section 4.8 and 6.2 for further guidance.
• The helideck status light signalling system shall be installed either on or adjacent to the helideck.
• The status light shall be visible from all approach angles, i.e. 360° in azimuth. In case of obstacles blocking visibility, additional lights may be added at other locations.
• While the helicopter is landed on the helideck, intensity shall be dimmed to maximum 60cd. At least one light shall be visible to the pilot when the helicopter is on the helideck, regardless of its
orientation to the deck. Note: Output light characteristics are the same for repeater light and main light when in “dim” mode.

Note: The light units when in combination with Tranberg control system are automatically monitored. Of this reason, according to CAA Paper 2008/01, redundancy light units and components can be omitted.
