Twin-rotor helicopters are generally a rare site here at Heli-Expo, but fresh off a busy firefighting season, Columbia Helicopters has brought one of its specially-equipped Boeing CH-47D Chinooks to the static display. During the 2016 fire season, the company’s two Chinooks, equipped for the first time with the world’s largest internal helicopter Fire Attack System (FAS) and their 2,800-gallon water tanks, logged more than 740 hours, or nearly half of the company’s seven-helicopter fleet’s usage. The fleet fought more than 50 fires in 16 states with an availability rate that exceeded 95 percent. The FAS was developed specifically for Columbia and it can discharge its entire tank in five seconds and can refill from a hover in less than a minute.
