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.
Above: An example of a fire map produced by the Air Affairs infrared mapping system.
A company with an unusual name, “Air Affairs”, has been mapping wildfires (or bush fires) in Australia since 1994. Not unlike the systems the U.S. Forest Service has been using since at least the 1970s, Air Affairs uses infrared line scanners to detect heat produced by the fires, even if they are apparently obscured by smoke.
That heat is then plotted on a georectified map and transmitted via a satellite link directly from the aircraft in a format compatible with Geographic Information Systems (GIS) used by the state fire authorities. The image data requires no further processing by fire personnel and is available for immediate use.
Air Affairs has two line scanners. One is permanently mounted in the belly of a Beechcraft B200T. The other is a pod which can be attached to one of the company’s Learjets.
Interestingly, the USFS has two similar aircraft with line scanners — a Citation jet and a King Air.
The National Park Service announced on its Facebook page on Friday than an unmanned aircraft system, otherwise known as a drone, took a test flight over the Paradise fire at Olympic National Park to gather infrared data.
An operational test of UAS on the Paradise fire at Olympic National Park took place recently. Learn more about the purpose of the flights and check out the footage.
Unmanned Aircraft System was a Success on the Paradise Fire
For the past week an unmanned aircraft system (UAS) was utilized on the Paradise Fire. The system was demonstrating possible applications in wildland fire management and suppression. UAS’s can supplement manned aircraft, especially at times of reduced visibility due to smoky conditions and at night when manned firefighting aircraft may be limited in flying.
The primary goal of the UAS on the Paradise Fire was to gather infrared information. This information assisted fire officials in pinpointing the fires perimeter and identifying areas of intense heat. The extremely large old growth trees in the area of the Paradise Fire create a thick canopy that makes mapping the perimeter and observing hotspots from the air very difficult without infrared capabilities.
This was an operational demonstration provided by Insitu, Inc. with no direct cost to the government. The demonstration was one of a series of ongoing missions to further UAS use on wildland fire in national parks and is part of an interagency strategy for UAS integration into wildland fire support. The Washington Department of Natural Resources (DNR) allowed the use of their land for the aircraft launch and recovery site. The purpose of the demonstration was to show the capabilities and effectiveness of unmanned aircraft technology on wildland fires. The ultimate goal for UAS use on wildland fire is to supply incident management teams (IMT) with real-time data products, and information regarding fire size and growth, fire behavior, fuels, and areas of heat concentration. Additional applications, such as search and rescue and animal surveys, may be explored.
As the fire season continues and more wildfires burn throughout the west, manned aviation resources are spread thin across the country and have become very difficult to acquire. In addition to supplementing aerial resources, UAS’s are quieter than manned aircraft, use less fuel, and present a much lower risk to employees.
This was not the first UAS to be flown in the Olympic National Park. The park partnered with the U.S. Geological Survey in 2012 to monitor sediment transport in the Elwha River as part of the Elwha restoration project using a Raven UAS.
The ScanEagle UAS that was flown on the Paradise Fire weighed approximately 50 lbs with a wingspan of 10.2 feet. The UAS was only operated within the Federal Aviation Administration (FAA) temporary flight restriction (TFR) area. The TFR has been lifted.
One of the two U.S. Forest Service infrared line-scanning aircraft, N149Z, has a serious maintenance issue that may take it out of service for the rest of the season. If it were an NFL player, it would be called season-ending Injured Reserve.
The Beechcraft Super King Air 200 (twin-turboprop) has a problem with the right engine mounting, which has not been completely evaluated yet, so it is difficult to estimate when it will be back in the air. But it could be out for the rest of the western wildfire season.
There are presently no privately owned infrared line-scanner aircraft on call when needed status. If necessary, contract infrared services could be hired through an Emergency Equipment Rental Agreement by the local unit or the Geographic Area Coordination Center, as was done by the Lassen National Forest in 2012 on the Ponderosa Fire in northern California.
The other USFS IR plane is a twin-engine jet, N144Z, a Cessna Citation II. It continues to be in the starting lineup. Occasionally in past years they have outfitted a King Air B-90 with IR equipment.
San Diego County will be adding a third firefighting helicopter to their fleet, implementing one of the recommendations in a report on the 14 fires that broke out in May in the northern part of the county. The Board of Supervisors on Tuesday allocated $5.2 million for another helicopter to become part of the County Sheriff’s stable of aircraft.
The Supervisors also approved contracting with the city of San Diego to use its night-flying helicopters for fighting fires or making rescues at night.
One MD500D. This is the oldest in the fleet, the workhorse of ASTREA since the late 1980s. The “D” model will eventually be replaced with a more powerful helicopter.
Three MD500F, better suited for high altitude and high temperatures than the MD500D.
Two Bell 205 A1++, for fire and rescue
One Bell 407 equipped with a data-link antenna and associated hardware which makes it possible to pass a live video feed to ground personnel. It is also equipped with a FLIR 8500 thermal imager with laser designator.
On Friday, September 5, 2014, the United Stated Park Police, a division within the National Park Service, held an awards ceremony recognizing and honoring FLIR for their dedicated service. FLIR representatives and U.S. Park Police officials gathered at the “Eagle’s Nest” located in Anacostia Park to commemorate FLIR’s contributions and continued support with Inaugural celebrations, 4th of July celebrations, and numerous special events.
U.S. Park Police’s Eagle 2 helicopter is equipped with a FLIR 8500 infrared and color sensor that provides stable thermal imaging as well as color video that assists with a range of law enforcement and rescue operations.
Pioneers in thermal imaging FLIR Systems designs, develops, manufactures, markets, and distributes technologies that enhance perception and awareness.
The image above is a screen grab from a video of very raw footage from the loaner multi-mission fixed wing aircraft that the Colorado Division of Fire Prevention and Control (CDFPC) is using until the two aircraft they purchased are delivered by December 1. The video includes visual and infrared images shot from the aircraft on several missions they have been flying since it was delivered a few weeks ago.
We can’t embed the video (which was advertised by the CDFPC on Twitter) but you can see it at YouTube. Unless you really enjoy seeing an aircraft sitting on the tarmac with the prop spinning, you can skip the first minute. The title of the video indicates that it is a work in progress; there is quite a bit of duplication.
Today the Department held another press conference to introduce the aircraft.
