Contracts are awarded through a negotiated procurement process, generally for 3-year periods, to assure the most cost-effective service is obtained. Data collected from through is not sufficient to provide statistically defensible analysis and results. Water is least effective, but most readily available.
The negotiated procurement as opposed to the sealed low bid process has, over the years, resulted in a significant improvement in airtanker availability for fire dispatch.
The VLAT initiated the retardant drop as identified by the smoke trail. We reached out with some questions to Global Supertanker, the company that operates the Supertanker, and they gave us this statement: AFUE is tasked to develop and implement performance metrics, technologies, and evaluation criteria in which effective tactical and strategic decisions are statistically supported.
Some water-dropping aircraft carry tanks of a guar gum derivative to thicken the water and reduce runoff. However, there have been cases of aircraft extinguishing fires long before ground crews were able to reach them.
Aircraft There are three primary kinds of aerial firefighting aircraft available within the U. The doors are controlled based on the area to be covered and wind conditions.
Small, medium and large helicopters carry from to 3, gallons of water, foam, or retardant in either buckets slung beneath the aircraft, or in fixed-tanks. Water is usually dropped directly on flames because its effect is short-lived. The report concluded that a low drop by the Supertanker uprooted and broke off trees and limbs Diagram from the Green Sheet.
Large fixed-wing airtankers have complex, computer controlled retardant dispersal systems capable of both precise incremental drops and long trailing drops one-fourth of a mile or more in length.
The air tanker that made the drop was T, a that can carry up to 19, gallons. Aerial Firefighting Tactics and Management Aerial firefighting is usually conducted to assist firefighters on the ground in achieving fire suppression objectives. These airtankers typically make retardant drops from a height of to feet above vegetation and terrain, at airspeeds from to knots.
Key Points The AFUE study will provide key information to define and track performance metrics for wildland fire aerial suppression aircraft.
This is particularly useful in rural areas where flying back to an airbase for refills may take too much time. Fire retardants are typically dropped ahead of the moving fire or along its edge and may remain effective for two or more days.
The Leadplane Pilot assigns airtankers to specific targets and frequently leads airtankers through drop runs for increased safety and efficiency of retardant drops.
Obscured by heavy vegetation and unknown to the VLAT pilot, a rise in elevation occurred along the flight path. Multi-engine airtankers are comprised of ex-military and retired commercial transport aircraft.
When a drop is made from the recommended height the retardant hits the ground as a mist, falling vertically, rather than the larger droplets you see with a gravity tank.
As proud members of the wildland firefighting community, we, too, have lost a brother. In this case, according to the report, the drop was made from approximately feet above the tree tops. The variety of aircraft available within U.
A few states also operate their own airtanker fleet.ultimedescente.com, Coeur d'Alene, ID. 5, likes · talking about this. As a collector of various fire shirts from the fires I've flown on I. Includes fire-extinguishing planes known as airtankers, firefighting helicopters, transports, and direction and command planes essential to successful firefighting.
Many rare, never-before-published images show firefighting aircraft in action/5(4). queensland fire and emergency services The conference went absolutely very well for us, it was interesting and useful. We enjoyed every moment, both of professional networking and the excellent. The use of aircraft to drop fire retardant, foam, or water to suppress wildfires is an essential wildland firefighting tool.
The speed, mobility and retardant delivery capability of aerial firefighting aircraft make them very effective resources in support of firefighters on the ground.
queensland fire and emergency services The conference went absolutely very well for us, it was interesting and useful. We enjoyed every moment, both of professional networking and the excellent atmosphere of communication between colleagues, the people who speak in the same ‘firefighting.
The Aerial Firefighting Use and Effectiveness (AFUE) Study was initiated in to answer a general, but complex question: “What are the best mixes of aircraft to do any fire suppression job?” Data collected from this study and other sources will be used to inform decisions about the composition of the interagency wildland firefighting aircraft fleet.Download
