Helicopters have become vital tools for high-altitude rescues, searches, and fighting wildfires worldwide. With the ability to quickly sweep over rugged terrain and remote regions, helicopters can assist aerial search parties in carrying water and fire retardants to control fires when it is too dangerous or challenging for ground personnel to reach. This article focuses on using helicopters in firefighting operations in Hong Kong.

In Hong Kong, the Airbus H175 Cheetah Helicopter is primarily used for mountain fire suppression operations. These helicopters are equipped with a standard fire bucket system and can be fitted with a “belly tank” with its own suction pump and fire foam delivery system if needed.

One of the advantages of helicopters in firefighting is their ability to carry a large amount of water across a significant rugged surface area multiple times to the fire frontline. Refilling the water is possible in shallow sources or reservoirs. Another advantage is their ability to transport firefighters and equipment to and from the fire lines. Commanders can use surveillance and mapping services to understand the incident better.

Despite their effectiveness, helicopters have limitations and risks. Pilots are at risk of unpredictable wind conditions, smoke, debris, and collisions with other aerial vehicles. Operating helicopters can be expensive, depending on their availability and funding. They are only suitable for some high-rise building firefighting operations, and the high air pressure from their blades would affect the fire conditions of the building fire.

Despite these limitations, helicopters remain a critical component of modern firefighting, helping to protect communities and the natural environment from the destructive effects of wildfires.
