Coulson Aviation has modified two helicopters so that they can be flown at night. The company, according to Vertical Magazine, took one of their four Sikorsky S61s and a Bell 206B Jet Ranger to Boise, Idaho to get Aviation Specialties Unlimited to make the modifications necessary to be compatible with night vision goggles (NVG).
Coulson also installed a hoist and a medivac interior on the S61, similar to the systems on Los Angeles County’s SH-3 Sea King helicopters, so that it could be used to extract injured personnel from remote areas day or night. This capability could save the lives of firefighters who are victims of accidents after sunset.
Two of the company’s S61s, including the NVG-equipped ship, are in Australia now working on a fire contract. Night flying is not part of the agreement but Coulson hopes to demonstrate to the authorities the benefits of fighting fire at night, when fires move more slowly and firefighting can be more effective.
The US Forest Service will experiment with one night-flying helicopter in 2013, even though helicopters have been fighting fire at night for decades.
