Jet Ranger - Firebird 305
Firebird 305 has multiple roles, including air attack, hover
exits, mapping of fires, FLIR (Forward Looking Infra Red) operations,
incendiary dropping, transport and lifting of external loads.
In the FLIR role a camera is fitted to the underside of the helicopter
with a screen monitor fitted inside the aircraft. The operator
can move the camera to scan under the ground for hot spots, which
can be almost impossible to detect by the naked eye. Ground personnel
can then be guided to these areas to cool them down.
Long Ranger - Firebird 337
Firebird 337 is also a versatile water-bombing helicopter with
a number of roles including air attack, water bombing, troop and
equipment transfers and FLIR operations. Air attack involves carrying
a Rural Fire Service or National Parks and Wildlife Service person
around the fires to supervise water bombing. When water-bombing
the pilots are able to liase with ground troops to find out what
targets have priority. Water bombing operations are conducted
using a Bambi Bucket, which can carry 550 litres of water and
foam, attached to a line of up to 150 foot long.

The main function of the BK 117 is water bombing. It is fitted
with a specially designed Simplex belly tank that carries 1200
litres of water and 160 litres of foam retardant. The chemical
is injected into the water en-route to the fire, and when the
load is dropped it leaves a foam residue on the ground, blanketing
the fire and therefore smothering its progress. The hingless rotor
system on the helicopter allows the pilot to accurately place
the water and load from water courses with tight access, the snorkel
is able to retrieve the water from as little as 18" water depth
and pump the tank full in 50 seconds. The BK 117 is also valuable
in the role of personnel and equipment transfer; and with its'
large clamshell doors is able to carry bulky items remote from
the cabin.
Helitack 334 has had an extensive fit out; along with the Simplex
belly tank, which is the first of its type to be fitted to a BK
117 the helicopter has also had wire strike protection gear fitted.
When in a fire support role, in times of poor visibility the helicopter
has five high-intensity synchronised lights to enhance its protection
from other aircraft.
Internally the radio suite has been increased by five more radio's
so that the pilot is able to communicate with everyone involved
with the fires from the command centres, down to the man on foot
at the fire. A global positioning tracking system is also fitted
to the helicopter, which sends an update of the helicopters position
every 90 seconds to the command centres. This allows tracking
of the helicopters activities by the fire fighting co-ordinates
without distracting the pilots whilst they are working in the
frantic environment of fire fighting.
