Question

How fires occured in forest are controlled esp by helicopter?

Answer 1

You should delete this question.If that is a question.

Answer 2

What a delightfully absurd, if somewhat inarticulate, question!!

Lets state the obvious:  they arent.  There is NO esp.  Think you're special: check out this website. http://www.randi.org/research/index.html   Hint: no one has collected.

Answer 3

how fires occurred in forest are controlled especially by helicopter?i mean if its this,however it's what makes sense the most, hmm... what some missing letters can do!

Answer 4

they are let free, vectored away from inhabited areas. it is sometimes not possible to extinguish the wildfires, the firefighters just stop the fire at certain directions and vector it. they dig the fire trenches. the same is with the helicopter. the question belongs to the aircraft section I think, not here.

Answer 5

There was one?

Answer 6

Yes, they use ESP to control helicopters and fires. And here is another little known fact, ESP is used to control Airplanes, the tides and to keep hurricanes from getting out of control.

Too bad they don't have ESP cars yet. I guess they are afraid that people without ESP will try to drive them and not be able to steer.

Answer 7

Because of a space covered by away than the land that's the reason helicopter use to fire extinguish

Answer 8

Forests play a crucial role for sustaining the human environment and because forest fires are among the largest dangers for forest preservation, it is not a surprise to see increasing state expenditures for forest fire control. Despite of this,annually millions of hectares of forests are still destroyed by fires. That this number has not declined implies that controlling fires is a complex task, and indeed forest

fires can become as large as 600 km² within 9 days and cost millions of dollars to extinguish (The Petawawa NF Institute 1982). Although most fires are extinguished quickly, a few forest (or bush) fires become uncontrollable for human intervention after which they cause huge damages to the environment and endanger human lives.E.g., Ash Wednesday, the SA & Victoria (Australia) fire disaster in 1983, burned 392 000 ha of (grass) land and killed 75 people (Moore/Trevitt 1991).

Steps in forest fire control.:

Forest fires depend on three things: fuel, heat and oxygen. Taking away one of them will put out the fire. Methods resources) for controlling the fire can be divided into airborne agents and ground agents. Airborne agents such as airplanes and helicopters drop water or chemical retardants in front of the fire and take away heat or oxygen. Ground agents such as trucks or land rovers are equipped with water tanks for directly attacking the fire. Other ground agents are

bulldozers, tractors or people equipped with e.g. chain saws. These agents cut firelines, which is an effective means for removing fuel. The choice of methods and equipment which are actually used depends on the country and kind of environment (Calabri 1982). Once a fire outbreak is signalled, the fire manager evaluates the situation and

makes an initial attack plan to stop the spread of the fire. This plan consists of a number of firelines (subplans) which break the fire-propagation. Then she allocates

resources from neighboring resource bases to fulfill all subplans. Once the resources have started the fight, the fieldcommander is in control. He coordinates the teams in

the field and gets a stream of online information which enables him to reevaluate plans constantly, e.g. if the situation gets too dangerous, he can choose to retreat.

Fire management decision support systems. Currently, a few EDSSs have been constructed to support fire managers in their decision making (Beer 1990, Avesani et al. 1993, Kourtz 1994). The CHARADE project (Ricci et al. 1994) is a software platform for the development of intelligent EDSSs, and has e.g. been used to construct a working EDSS for managing first intervention in forest fires. The planning

system integrates case-based reasoning and constraint reasoning (Avesani et al. 1993) and is integrated with a Geographic information system (GIS) for displaying

spatial data and a model for simulating forest fires. Kourtz (1994) describes various applications of expert systems and AI algorithms to support managing Canadian 380

forest fires. Example applications are improving fire detection, computing costeffective resource allocation and predicting forest fire occurrence.

Controlling Forest fire :

The helicopter can move to each of the four directions at high speed and drop a waterbomb. The positions on which water is distributed after dropping a waterbomb depends on the

direction and speed of the helicopter. The most effective place to drop water is in front of the fire. The effect is that waterbombed cells will have their fire activation decreased. Once the agents' water reservoirs are empty, they have to return to refill which takes some time. These agents are characterized by their flying speed, landing time, taking off time, refilling time, and the size of the waterreservoir. The cost of putting them into operation depends on the total distance traveled and the number of landings.
