Fleet and Performance
DFES currently operates a sophisticated aerial fleet to respond rapidly to fire and emergency incidents, strengthen firefighter capabilities and protect lives and property during Western Australia’s (WA) volatile bushfire season.
The firefighting fleet consists of six Bell 214B Type 1 helitaks with 2,700 litre water lifting capacity each, one Sikorsky S64 Type 1 High Volume Erickson Air Crane with 7,000 litres water lifting capacity and one air intelligence helicopter to provide fire mapping information to incident controllers and one air attack supervisor helipcopter.
Type 1 helitaks may also be used to rescue and relocate people during significant natural disasters such as flooding and to transport food and water to isolated communities.
Each year the WA State Government and Australian Federal Government allocates funding to enhance WA’s helicopter fleet, which include deploying additional aircraft from overseas to provide assistance and combat fires during the bushfire season between December and April.
DFES’s fleet of helicopters plays a pivotal role in supporting ground firefighters to preserve and protect life, property and the environment in WA.

Deployment and Activity
Helitaks are deployed when public safety and or assets are considered at imminent risk, when firefighting crew are in immediate danger, during extreme fire behavior and when high fuel loads are likely to accelerate and spread the fire.
Since their introduction in 2002, helitaks have proved to be a versatile, powerful and efficient aerial resource supporting firefighters to protect and save lives and homes.
Under the Bush Fires Act 1954, Fire Brigades Act 1942 and Emergency Management Act 2005, laws and legislation are in place allowing helitaks to collect water from sources found on private residential and commercial land.
Fresh water is sourced from lakes, dams, streams, reservoirs and portable collar tanks from points that offer safe and clear entry and exit paths free from infrastructure and obstructions.
Salt water is not used as spray leaves residue on the helicopters mechanical components and interferes with visibility compromising the safety of the crew.
Water sources are chosen based on proximity to the incident, access to the water source, visibility, level and suitability of water available with little or no potential risk to public spectators.
Helitaks are unable to collect water from domestic swimming pools as a 100 metre clearance is required for approach and take-off as the helicopters create substantial rotor wash and dangerous turbine heat emissions that present a risk to people and property.

Tracking
Helitak activity is closely monitored and recorded in the DFES Air Operations computerized database to enable accurate reporting to WA State Government and the National Aerial Fire Fighting Centre (NAFC).
