Helitack
Helitack crews are teams of wildland firefighters who are transported by helicopter to wildfires. Helicopters provide rapid transport, enabling helitack crews to quickly respond and assess a wildfire situation. Helitack crews may land near a wildfire or, if equipped and trained, rappel from a hovering helicopter. Once on the ground, crews build firelines using hand tools, chainsaws, and other firefighting tools. They often remain overnight in remote locations. After they have completed their assignment, crew members may pack up to 120 pounds of equipment over difficult terrain to reach a pick-up point. Rappellers often prepare helispots (helicopter landing zones) that provide better access to a fire. Helicopter crew members may also perform other duties such as tree falling, firing operations, and managing helibases. Terminology Helitack The term ''helitack'' first appeared in a 1956 ''Los Angeles Times'' article, which described the "first of a series of tests—tabbed the Hel ...

CDF Aviation Management Program
The CAL FIRE Aviation Management Program is a branch of the California Department of Forestry and Fire Protection (known also as CAL FIRE). Due to the frequency and severity of wildfires in California, the state has elected to establish its own aerial firefighting force rather than rely solely on national resources. The Aviation Management Program is based at McClellan Airfield near Sacramento, California. Overview In support of its ground forces, the California Department of Forestry and Fire Protection (CAL FIRE) emergency response air program includes 23 Grumman S-2T 1,200 gallon airtankers, 12 UH-1H Super Huey helicopters, and 16 OV-10A airtactical aircraft. It is in the process of adding 7 C-130H 4,000 gallon airtankers. These aircraft are stationed at 14 airtanker and 11 (10 CAL FIRE, 1 joint CAL FIRE/ San Diego County Sheriff) helitack bases located statewide, and can reach most fires within 20 minutes. During high fire activity, CAL FIRE may move aircraft to better provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bell 204/205
The Bell 204 and 205 are the civilian versions of the UH-1 Iroquois single-engine military helicopter of the Huey family of helicopters. They are type-certificated in the transport category and are used in a wide variety of applications, including crop dusting, cargo lifting and aerial firefighting. Development Bell designed its ''Model 204'' in response to a 1955 United States Army requirement for a utility helicopter. The 204 was a giant step forward in helicopter design, being one of the first to be powered by a turboshaft. The turboshaft engine radically improved the practicality of the helicopter due to its light weight and high power-to-weight ratio, lower fuel consumption, and lower maintenance and operating costs. The use of a turboshaft in the 204 allowed it to carry a useful payload over respectable ranges and at reasonable speeds, which resulted in the 204 and subsequent 205 becoming the most successful western helicopter series in terms of numbers built.Fra ...

Wildfire
A wildfire, forest fire, bushfire, wildland fire or rural fire is an unplanned, uncontrolled and unpredictable fire in an area of combustible vegetation. Depending on the type of vegetation present, a wildfire may be more specifically identified as a bushfire( in Australia), desert fire, grass fire, hill fire, peat fire, prairie fire, vegetation fire, or veld fire. Some natural forest ecosystems depend on wildfire. Wildfires are distinct from beneficial human usage of wildland fire, called controlled burning, although controlled burns can turn into wildfires. Fossil charcoal indicates that wildfires began soon after the appearance of terrestrial plants approximately 419 million years ago during the Silurian period. Earth's carbon-rich vegetation, seasonally dry climates, atmospheric oxygen, and widespread lightning and volcanic ignitions create favorable conditions for fires. The occurrence of wildfires throughout the history of terrestrial life invites conjecture tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nelson, British Columbia
Nelson is a city located in the Selkirk Mountains on the West Arm of Kootenay Lake in the Southern Interior of British Columbia, Canada. Known as "The Queen City", and acknowledged for its impressive collection of restored heritage buildings from its glory days in a regional silver rush, Nelson is one of the three cities forming the commercial and population core of the West Kootenay region, the others being Castlegar and Trail. The city is the seat of the Regional District of Central Kootenay.

UH-1 Iroquois
The Bell UH-1 Iroquois (nicknamed "Huey") is a utility military helicopter designed and produced by the American aerospace company Bell Helicopter. It is the first member of the prolific Huey family, as well as the first turbine-powered helicopter in service with the United States military. Development of the Iroquois started in the early 1950s, a major impetus being a requirement issued by the United States Army for a new medical evacuation and utility helicopter. The Bell 204, first flown on 20 October 1956, was warmly received, particularly for the performance of its single turboshaft engine over piston engine-powered counterparts. An initial production contract for 100 ''HU-1A''s was issued in March 1960. In response to criticisms over the rotorcraft's power, Bell quickly developed multiple models furnished with more powerful engines; in comparison to the prototype's Lycoming YT53-L-1 (LTC1B-1) engine, producing 700 shp (520 kW), by 1966, the Lycoming T53-L-13, c ...

A Fire Helicopter With Helicopter Bucket
A, or a, is the first letter and the first vowel of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version can be written in two forms: the double-storey a and single-storey ɑ. The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English grammar, " a", and its variant " an", are indefinite articles. History The earliest certain ancestor of "A" is aleph (also written 'aleph), the first letter of the Phoenician alphabet, which consisted entirely of consonants (for that reason, it is also called an abjad to distinguish it fro ...

National Wildfire Coordinating Group
The National Wildfire Coordinating Group (NWCG) was formed in the United States as a result of the aftermath of a major wildfire season in 1970, including the Laguna Fire. The 1970 fire season underscored the need for a national set of training and equipment standards which would be standardized across the different agencies. NWCG included representatives from the United States Forest Service, the Bureau of Land Management, the National Park Service, the Bureau of Indian Affairs, the U.S. Fish and Wildlife Service, and the National Association of State Foresters. After a series of meetings in the early 1970s, the NWCG was officially chartered by the Secretaries of the Interior and Agriculture in 1976. Among the notable results of the NWCG has been the adoption of the Interagency Fire Qualifications Rating system, more commonly known among firefighters as the "red card" qualification system; the establishment of the series of training classes associated with the red card sy ...

Handcrew
Handcrews are diverse teams of career and temporary wildland firefighters. The crews typically consist of 18 to 20 firefighters but can also contain 4 to 6 and 8 to 10. These crews have the responsibilities of constructing firelines – strips of land cleared of flammable materials and dug down to mineral soil. These lines are generally constructed around wildfires to control them. Another type of line handcrews create is saw line. This is line where all trees limbs are removed up to shoulder height and all small trees and brush is cut down. All the limbs and trees are then carried outside the line and scattered. These are also called ladder fuels that allow the fire to climb up into the canopies which makes controlling a fire much more difficult. Sawyers do the cutting and swampers do the moving of the debris. Depending on the size of the crew there can be between 1 and 5 swampers per sawyer. Other jobs include burn outs, gridding for spot fires, and mop up after the fire is cont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aérospatiale Alouette III
The Aérospatiale Alouette III (, ''Lark''; company designations SA 316 and SA 319) is a single-engine, light utility helicopter developed by French aircraft company Sud Aviation. During its production life, it proved to be a relatively popular rotorcraft; including multiple licensed manufacturers, more than 2,000 units were built. The Alouette III was developed as an enlarged derivative of the earlier and highly successful Alouette II. Sharing many elements with its predecessor while offering an extra pair of seats and other refinements, it quickly became a commercial success amongst both civil and military customers. Further variants were also developed; amongst these was a high-altitude derivative, designated as the SA 315B Lama, which entered operational service during July 1971. The Alouette III was principally manufactured by Aérospatiale; the type was also built under licence by Hindustan Aeronautics Limited (HAL) in India as the HAL Chetak, by Industria Aeronautică Ro ...
