Using infrared to detect gaps in retardant coverage

(Last Updated On: June 16, 2017)

One of Colorado’s Multi-Mission Aircraft shot this infrared video of an air tanker making a drop on the 500-acre Hunter Fire southwest of Meeker, Colorado about five days ago. Heat from the fire shows up as white and water or retardant drops are dark grey or black. It appears that the air tanker is attempting to fill in a gap in a retardant line, but as you can see, incomplete coverage remains.

The air tanker is very hard to see — it’s just a little dot, but it becomes obvious when the retardant is released. This shows the value of an air attack ship having infrared capabilities; the crew can direct aircraft to fill in gaps in retardant lines, in addition to mapping the fire perimeter.

Single Engine Air Tankers are a very important tool in the firefighter’s tool box, but this also shows the value of large and very large air tankers. A much longer drop means fewer gaps to worry about.
