practicable and final approach and take-off area lights are
available.
5.3.8.3 The touchdown and lift-off area lighting system
for an elevated heliport or helideck shall consist of:
a) perimeter lights; and
b) floodlighting andfor luminescent panel lighting.
Note.- At elevated heliports and helidecks, su$ace texture
cues within the touchdown and 113-.9ff area are essential for
helicopter positio?zing during the final approach and landing.
Such cues are provided by using floodlighting or luminescent
panel lighting or a combination of these two foms of lighting,
in addition to perimeter lights.
5.3.8.4 Recommendation.- Touchdown and lifi-off area
floodlighting or luminescent panel lighting should be provided
at a suvface-level heliport intended for use at night when
enhanced sulface texture cues are required.
Location
5.3.8.5 Touchdown and lift-off area perimeter lights shall
be placed along the edge of the area designated for use as the
touchdown and lift-off area or within a distance of 1.5 m from
the edge. Where the touchdown and lift-off area is a circle the
lights shall be:
a) located on straight lines in a pattern which will provide
information to pilots on drift displacement; and
b) where a) is not practicable, evenly spaced around the
perimeter of the touchdown and lift-off area at the
appropriate interval except that over a sector of 45" the
lights shall be spaced at half spacing.
5.3.8.6 Touchdown and lift-off area perimeter lights shall
be uniformly spaced at intervals of not more than 3 m for
elevated heliports and helidecks and not more than 5 m for
surface level heliports. There shall be a minimum number of
four lights on each side including a light at each comer. For a
circular touchdown and lift-off area, where lights are installed
in accordance with 5.3.8.5 b) there shall be a minimum of
fourteen lights.
Note.- Guidance on this issue is contained in the Heliport
Manual.
5.3.8.7 The touchdown and lift-off area perimeter lights
shall be installed at an elevated heliport or fixed helideck such
that the pattern cannot be seen by the pilot from below the
elevation of the touchdown and lift-off area.
5.3.8.8 The touchdown and lift-off area perimeter lights
shall be installed at a floating helideck, such that the pattern
cannot be seen by the pilot from below the elevation of the
touchdown and lift-off area when the helideck is level.
5.3.8.9 On surface level heliports, luminescent panel
lights shall be placed along the marking designating the edge
of the touchdown and lift-off area. Where the touchdown and
lift-off area is a circle the luminescent panels shall be located
on straight lines circumscribing the area.
5.3.8.10 On surface level heliports the minimum number
of panels on a touchdown and lift-off area shall be nine. The
total length of luminescent panels in a pattern shall not be less
than 50 per cent of the length of the pattern. There shall be an
odd number with a minimum number of three panels on each

with a distance between adjacent panel ends of not more than marking can be correctly identified.

5.3.8.23 Recommendation.- fie average horizontal

a unvonnity ratio (average to minimum) of not more than 8:l

to the perimeter lights. They should be placed around a
touchdown marking where it is provided or coincident with
heliport identification marking.
