Helitorches are used by helicopters for aerial ignition of all types of large-scale prescribed fires including oil spills. Helitorches will operate under any helicopter equipped with a cargo hook and 28 VDC power. A 55-gallon tank supplies special fuel to a propane ignition system which then supplies a uniform stream of fire to the targeted area. A support trailer with mixing tanks to prepare the gel fuel is required. The pilot controls the helitorch operation. The burn boss is in a separate aircraft or strategic ground site.
