TEF 9980 STATUS LIGHT -
INSTALLATION AND USER MANUAL
3 NUMBERS AND LOCATION OF LIGHT UNITS
The number and location of light units should be considered in coop-
eration 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.
Proposed location of light units:
M
= Main light
R
= Repeater
