5.3.8 Touchdown and lift-off area lighting system
Application
5.3.8.1 A touchdown and lift-off area lighting system
shall be provided at a heliport intended for use at night.
5.3.8.2 The touchdown and lift-off area lighting system
for a surface level heliport shall consist of one or more of the
following:
a) perimeter lights; or
b) floodlighting; or
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 liftoff 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 degrees 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 (Doc 9261).
