$12M fire bomber trial (http://www.cfaconnect.net.au/index.php?option=com_k2&view=item&id=2489:&Itemid=42)

Is it just me, or do we not have the capability to develop something like this "in house"? Or, is it more a case of spending copious amounts of dollars on foreign equipment is easier to palate than having faith in local industry?

(No offence intended to the foreign crews btw):ok:

Maybe they'll just treat this like a test, if all goes well they'll look into getting the aircraft purchased and modified here in Aus?

I always wondered why you could not say develop a load package for a C-130 that could do this sort of job. A roll on roll off baffled tank with a dump valve hanging out the back.

The C-130 loads up, heads out and does its thing. Meanwhile a second load tank is being refilled on the ground ready to be switched over when the aircraft returns, rinse, repeat.

I am sure there are probably practical reasons why this would not work (too slow to turn around, not the right dumping method, aircraft not suited for the job perhaps) but it always stuck with me when we had big fires that we had a number of large capacity transport aircraft with very capable low level pilots sitting idle.

I have actually had something to do with "rolling off" and "rolling on" a prototype military something into and out of a Hercules and the idea of a five minute turn around is a fantasy after the design of the thing is engineered and tied down to military specifications.

You need to think litres per hour delivered to the fire front. Size isn't everything.

As always...the CFA want this to fail.

How much refurbing of our already owned Trackers can we get for 12mill?

Just wish these twits would get a team of 415 (http://www.bombardier.com/en/aerospace/products/amphibious-aircraft/firefighting-techniques-and-technologies?docID=0901260d80009039)s and just keep out of the way and let the crews work.

The DC-10 was a $10 million trial and appeared to be a political reaction to save face to the Russian alternative suggested by the Libs. Could never see how that would ever be as effective as Elvis & friends. The turn around time was not pretty and the Skycrane could dump more liquid on target than the DC-10.

Where was the 10 going to be based? Moorabbin, no, only B767s land there. Essendon, no, too noisey for the home owners. Tulla, mmmm, that would be good having an empty firefighter getting priority over regular users. Now where else is there??????? :rolleyes:

This subject seems to pop up every 6 months or so.

The Convair is a good machine, but we have too few airports equipped to handle it.

The RAAF tried a MATTS system in the back of a Herc in the early 80's. Unfortunately their lead time to fight a fire meant that the fire usually got the upper hand. Not enough flexibility.

The DC-10 was a knee-jerk, and unsuitable for the job here.

Australia already has the answer; lots of Airtractor 802's and very skilled and knowledgeable crews, but it seems the authorities here want an overseas solution. Can't imagine why, as this usually results in a very expensive, less than perfect outcome.

I've oft wondered why the Bombardier CL-415 was discounted. WS was the Australian agent in the mid 90's and tried to generate interest, without success.

As I understand, it only requires shallow water, can load 6000 litres in seconds. From the Bombardier web site:Aerospace > Products > Amphibious Aircraft > FAQs (http://www.bombardier.com/en/aerospace/products/amphibious-aircraft/faqs?docID=0901260d800104c2)

How much distance does the Bombardier 415 take to scoop its load?

The Bombardier 415 is very manoeuvrable. If a body of water is 1,341 metres (4,400 feet) long by 90 metres (300 feet) wide and 2 metres (6 feet) deep, without floating debris, then it is scoopable*. Only 400 metres (1,350 feet) are actually required on the water, the remainder being needed for approach and climb-out. Of course, these distances can be reduced by scooping partial loads or scooping while turning. Speed on the water while scooping is 75 knots. Approximately 10 to 12 seconds are required between touchdown and lift-off to scoop a load.

You need lakes for a CL415, Canada has lost of them, we don't. I can't speak for NSW or Rocky valley near Falls Creek, but Lake Eildon would be a nightmare for them in my opinion, especially when we are talking about winds.

You have reasonably high terrain to the South and East plus the Eildon State Park Ridge in the middle plus the power lines (which have already claimed Four Lives and really are invisible) there is considerable turbulence, then there are the snags, and of course you would have to chase the water skiers off it.

You might be able to use the Lakes like Mokoan near Benalla and the Nagambi pondage. The Golbourn and Murray rivers aren't wide enough.

I think you will find that WS and company actually had 2 CL215's in country for a while, and I believe that they where quite successfully deployed on bushfires around Vic and SA around 98?? GB was the tech pilot, and Port Phillip bay seemed to work ok, but there where some issues that aren't flashing up..

Hello all,

Do not look at the Convair as a replacement to the ag planes or heli's. Look at them as another member of the team.

- The retardant tankers help direct fire movement by laying long lines of retardant along the flanks of a fire.

- Helo's and Ag planes help with spot fires as well as knocking down the fire intesity with bucketing etc.

- Ground crews go in and put out the fires.

We have been missing a part of the equation in this country. I just hope that they are allowed to work effectively and not handicapped before they even get off the ground. If this works out then we should be pushing for an in house solution.

* provocative title above ignores fuel costs

Opinion: World's Best Fire-Fighting Plane Ignored

By John D. Anderson

CALGARY, Alberta, Canada, March 23, 1999 (ENS) - The World Trade
Organization and United Nations agencies ought to act...like firefighters.
These organizations ought immediately to recommend a Russia-based, global
firefighting service utilizing the heavy-lift modern jet, the Ilyushin-76TD.

The world's largest, most powerful, firefighting aircraft - the
Ilyushin-76TD (Il-76) - sat on a runway in Russia in 1997 and 1998 while the
world's biggest, most wasteful wildfires consumed valuable animal habitat
and timber in Asia, Africa and South America. These fires caused many deaths
and health problems and exacerbated a worsening global warming situation.

This heavy-lift, modern-era, jet aircraft carries up to 135,000 pounds of
liquids; five-plus times the liquids load of the next-largest fire-fighting
planes, North American waterbombers.

The World Trade Organization (WTO) and the United Nations Environment
Programme (UNEP) could organize and deploy the Il-76 for worldwide fire
fighting through a three nation integrated service known as Global Emergency
Response.

Global Emergency Response is a comprehensively integrated Il-76 aircraft
emergency service complete with spares and a certified, qualified crew of
eight per aircraft for global fire fighting and other disaster and
humanitarian relief missions. It involves experts in Russia, Canada and the
United States.

WTO recognized in its high-level trade and environment symposium last week
that solutions to world environmental problems, fire among the chief
problems, may be hampered by trade barriers and national rules and
regulations. That is the WTO's expertise. So it can and should facilitate
utilization of leading technologies such as Il-76 with solid policy.

In sufficient numbers, this aircraft and its gifted Russian crews should
seasonally stand by, at strategically located runways the world over, ready
to stop the burning. Not inconsequentially, providing this service would
allow the Russian Federation to make the kind of money it will take to
breathe new life into its own flagging firefighting forces.

The tanking system used by Global Emergency Response can fit into any Il-76
and there are 100s of them in varying states of repair from brand new to
fair. These aircraft fly daily in cargo duty throughout the world. Tanking
systems can be manufactured in short order as they are simply large aluminum
cannisters with huge sealed hatches in the rear.

The Il-76 is large enough to handle the biggest fires that cause 95 percent
of the forest destruction globally.

There is no good reason this uniquely capable aerial firefighter could not
now be deployed to stop unwanted burning everywhere: from urban interface
and agricultural areas in Australia, California, and Florida, to bush,
savanna, and rainforest in Latin America and Southeast Asia, to the great
boreal forests of the north and the grasslands of Africa.


After much prodding from Global Emergency Response backers in North America,
the U.S. Forest Service, an acknowledged world leader in wildfire
suppression, tested the Il-76 aircraft at a British runway in September
1994.

U.S. Forest Service testers jumped up and down yelling "perfect, perfect" in
reference to the liquids drop characteristics and flight handling
capabilities during the drop. They published a press release acknowledging
the utility of the Russian giant. But then the U.S. Forest Service testers
went on to publish in the U.S. and Canada, an equivocal technical report.

We at Global Emergency Response think the U.S. Forest Service wrote the
technical report the way they did to keep the system at status quo. They
feared competition, and they especially didn't want to be shown up by the
Russians.

Extra long runway lengths were said to have been needed as the aircraft is a
heavy, big one. On the other hand, an aircraft like this will rarely go out
with full fuel, yet the component of fuel weight was added in to produce a
ridiculously long runway requirement. In reality, for such a big aircraft,
the runway requirements are short. For this and other reasons, the Russian
engineers called the report "unprofessional" in certain material respects.

Even after the 1998 Florida blaze near Daytona that caused the cancellation
of the Daytona 500, and a forest fire induced evacuation from Salmon Arm,
British Columbia, North American agencies continue to deny their citizens
and their environment the Russians' offer of the best, most cost-effective
big-fire protection.

Since 1995, the U.S. Forest Service has reneged on its undertaking to see
the Il-76 through a round-peg-in-square-hole domestic approval process which
would virtually assure the Russians worldwide acceptance of their premium,
yet affordable, firefighting service.

The services of the Il-76 tankers are charged by the hour - US$10,000 per
hour plus fuel. This rate is 184 percent more cost effective per pound of
liquid delivered to the fire than the largest Canadian tanker, the DC-6.
Figures for comparable U.S. fire-fighting planes are not available.

In Canada, without independent testing, firefighting agencies seized upon
the U.S. Forest Service tech-report's perceived downside. They advised their
ministers there were too many iffy areas and that further testing, possibly refinement, would be necessary. Canadian politicians, expressing
conditional support for the plane, deferred to the United States to resolve
any outstanding technical questions.

Even two seasons for record fire suppression expenditures - 1995 at Cdn$.5
billion and 1998 at Cdn$.7 billion failed to motivate Canadians to move on
the Russian aircraft service or even see it for themselves. This in the face
of government generated evidence that the heaviest hitters in Canada's
fleets' of fixed-wing, firefighting aircraft are getting too long in the
tooth to see safe fire action very much longer.

Efforts have been made to deploy the Il-76 to Indonesia, Brazil, and Mexico,
all to mysteriously inconsequential ends.

Australians entertained a demonstration of the Il-76's tanker potential at
the southern hemisphere's largest airshow in March 1995. Australian
firefighters saw right through the U.S. Forest Service's test report and
took the Il-76 to a test of their own later that year in Moscow. Finding the
aircraft and its handling characteristics quite satisfactory, the Aussies
still neglected to hire the Russian service in ensuing seasons.

Australasia inaction on the big Russian tanker cost Indonesia and associated
ASEAN countries dearly in 1997 and 1998. By some estimates, before health
costs, those fires cost US$4.4 billion.

The tiny aircraft Australia and other countries were able to send Indonesia,
even U.S. heavy haulers, were singularly unimpressive against the fury of
the rainforest fires on the Indonesian island of Borneo and especially
against the perennial, deep peat fires that will not go out.

It wasn't until the fury of the worst fires in 100 years hit Greece last
summer that a country outside the Russian Federation was able to muster the
Russian giant quickly to subdue two of its biggest fires. In Greece, the
Russian fire weapon finally and conclusively broke through
barriers-to-entry local firefighters the world over were throwing up.

UNEP and the United Nations Disaster Assessment and Coordination agency have
a lead on global fire information, an area surprisingly not all that well
documented.

According to the 1999 UNEP report "Wildland Fires and the Environment: A
Global Synthesis,"
up to 40 percent of carbon dioxide and 38 percent of tropospheric ozone
comes from biomass burning.

Analysis shows that five percent of the wildfires - the big ones - cause 95
percent of the destruction.

Under a perverse provision of the Kyoto Protocol to the Framework Convention
on Climate Change, carbon balance accounting does not take disastrous
biomass burning emissions into account unless it is "prescribed burning,"
done to remove fuel. This is a disincentive to better fuel management at the
same time as it is a nod to large-scale biomass burning, no matter how
caused.

Human interaction with forests causes up to 90 percent of this waste. Let's
take a look at a bigger, better, globally-organized firefighting weapon -
the Il-76 tanker system.

The World Trade Organization and the United Nations agencies should apply
Rio Earth Summit principles of sustainability to battling fires around the
globe.

Let's deploy the Russian giant firefighting tanker now, before we sit down
to plan and produce a sister to the World Trade Organization, the World
Environment Organization.

I didnt think the CV580 were still in production?

Kelowna Flightcraft in BC, Canada has the type certificate and produces a remanufactured uprated 580 known as the 5800. Stretched 14 ft with 501-22g engines. Nice machine and basically new.

The Convair is a good machine, but we have too few airports equipped to handle it.

Ummm there are two 580's running in and out of YSBK.....how big an airport do you think they need?

11th Sep 2010, 07:29
The DC-10 is too large for the urban interface. The problem was that the amount of "liquid" that the aircraft dropped was dangerous to persons on the ground and also to structures. At what point do you determine to destroy something to save something?

Fires, Aerial assets are a great tool, especially if you can get them there quick enough. Western Australia has the right idea with the response to the fire. There are area's where as soon as a 000 call is made the helicopters or At802/602 are mobilised. NSW is a different story and VIC is also again a different story where you have to go through managers etc to get the aircraft mobilised.

It is great to see some CV580's that not only can drop retardant but also water. Also interesting to note the extra S64 that is going to be deployed.

So there will be 3 x S64's, 2 x S61's, 2 x CV580's and the rest made up of AT502,602,802, B212, B412, B206, AS350 etc

As for the Trackers, it would cost a lot of money to get them up to scratch, then you have maintenance, crew's etc, it ends up being cheaper per year to bring in aircraft from overseas with full crew and maintenance support. ie it cost the government 10mill to have the 2 CV580's here as it would cost say 15 mill a year to have maintenance, crew, insurance etc for 2 trackers.

It is true that you need the ground crews to back up the aircraft dropping water or it is pointless. Here is a good link so everyone understands http://www.bushfirecrc.com/research/downloads/The-Cost-Effectiveness-of-Aerial-Fire-Fighting-in-Australia.pdf

In 1988 it cost the Canadians 8 million each to convert Trackers, that wouldn't include repairs from sitting around for twenty years. You then have an Aircraft that carries 3000 litres, same as an 802.

The largest and fastest of the water bombers is the turbofan jet Ilyushin-76TD (Il-76). It can reach a fire anywhere in the world within 12 hours. Carrying 11 gallons (42,000 litres) of water and fire retardants – 4 times as much as a C-130 – it can, in one run, dump enough water to cover 6 double-wide football fields, or an area 0.7 miles (1,1 km) in length.

See: World’s largest water bomber and heli firefighters :
http://didyouknow.org/firefighters/

42,000 liters is 14 lots of 3,000 liters . . .

and all that for only 10k US + fuel an hour

Why not use the Russkies and nuke the fires with Gods gift to fire fighting?

Engineer_aus
12th Sep 2010, 12:03
42,000lts is too much. Read all the documentation that the Australian authorities have provided, that is why the DC-10 is not coming back. Sure its fine for large unpopulated area's but not here in Australia.

12th Sep 2010, 12:14
Here is a good link so everyone understands

It is so nice to see the bean counters at it. I am sure that anyone who is in the line of a fire front does not care one iota about the cost benefit ratio. Whether it is a DC10 or 5x802s attacking the fire. All they want it the fire out.

Perhaps we could re-visit at least one of the earlier discussions on this (http://www.pprune.org/dg-p-general-aviation-questions/394962-new-water-bomber-victoria.html).

I particularly liked the contributions from "FarmerPete" - a long-time volunteer firefighter. His view is that the most cost-effective method was a mix of ground and air, with improved ground equipment being a cost-effective option. Budgets for firefighting are not unlimited.

I know this comment is a little late but I have just had the opportunity to read the report on the DC10 conducted by the Bushfire CRC. The conclusions about it being dangerous in urban areas and being dangerous to on ground firefighters are laughable. Any firebombing aircraft is dangerous if it is operated outside procedures and when operations involve untrained or incompetent personnel. An AT802 too low or too fast will make a complete mess of anything directly underneath it. I suspect strongly that there were political elements operating in our fire agencies that didn't want the DC10 for whatever reason. (NAFC, AFAC, CRC)

As far as operations go, on Black Saturday the DC10 would have made little difference in the heat of battle but the real benefit of this kind of aircraft is that it can be used early on such days to make sure any fires that are still burning are rounded up before the day gets hot and any existing fire edges become uncontrollable. The Royal Commission missed this point completely instead focusing on smaller aircraft out the door quicker. This concept is OK except on a day like that unless you get the aircraft overhead in about 5-10 minutes the chances of doing any good are minimal. (B212 start up about 6-10 mins it think).

The way in which the DC10 has been discredited is disappointing and short sighted. Unfortunately the things that were found "wrong" with this aircraft have eliminated ever using the big air tankers in Victoria/Australia. B747s and IL76s all would have exactly the same safety issues and for that matter the Convair 540's that are proposed/happening this season will struggle if the procedures and training allow people or assets in the path of drops.

Australia's aerial firefighting capability has been established and built up over many years using common sense and sound technical evaluation. I guess that it is inevitable with the kind of $ surrounding a DC10 that politics and egos come into play comensurate with the money at stake.

Just my opinion.

An AG pilot was telling me recently that they called for the DC10 for a fire near Hamilton. The pilots were with the aircraft but the crew had already gone home (mid afternoon). It was a perfect opportunity for it to show it's worth and it missed out badly.

Did it ever fight a real fire in Victoria?

3rd Dec 2010, 03:16
As a tax payer, I would prefer the C-130's to be used even if it mean't a shorter life span. Better to burn out than rust away.
But they would have to be operated by someone else besides the military.

It did a job up near Mildura but I think it was more about testing the gear than actually needing it - which I guess given the circumstances was an OK thing to do. It would have been interesting to see it work in a situation where it had jobs in different parts of the State in quick succession.

G'day all,
Just consider this before demanding heavy aerial water bombing a/c......

When you see 9000lt of retardant from Elvis coming through the tree canopy, it is ripping branches off so maybe another couple of tonnes of wood falling with it, it destroys everything on the ground below and on slopes, it creates a destructive flood if the canopy has not dispersed the fluid enough. Imagine what 45tonnes from a DC10 will do.............

A slow moving helo can direct the drop accurately, they can see people on the ground, fire trucks and property clearly and funnily enough, usually the fire too! A DC10 cannot and more importantly the height it is above the canopy (a matter of a few metres)also increases the risk of bird strike with a heavily ladened a/c. A helo can carry out multiple drops in the same time as the DC10's turn time and drop it much more effectively to assist the ground crews, what's more, probably carry up to the EQUIVALENT payload as a DC10 depending on the helo type, in the time it takes the DC10 to refuel, reload and return to the fight.

In all likelihood people WILL be injured and property damaged/destroyed with a/c dropping big loads, it probably slows down the work rate other a/c & helo's due to clearance issues. Certainly any ground crews and equipment must be removed from the drop zone or risk damage or injury. All this takes time and fighting a wild fire, time is CRITICAL to its control.

Unless you have been on the ground fighting a fire with aerial bombing or been involved in actual aerial fire fighting ops, you simply dont know what you're talking about.

Armchair generals have never won wars and probably cause politicians to waste taxpayers money, which should be put into essential gear like protective clothing, GPS, EPIRB's, comms for ground crews or more helo's for water bombing etc. Me thinks this is a much better use of taxpayer funds.............

Another factor to consider is the increased tendancy for people to move into the bush for a tree change experience. From memory the DC10 cuts a path about 1.5km long, in the typical bush setting within 1.5hrs drive time of any capital city this one drop could possibly hit anywhere between 2-10 houses. At around $300k-$600k or more per house the $10m for a DC10 for a season is quickly equaled in damages to property if the fire fighting agencies get it wrong.............Remember the Yanks were using 500kg concrete laser guided bombs to smash Iraqi armour in residential areas, just imagine what a misguided payload of 45tonnes of water/retardent would do to people/vehicles/property........

So unless you have flown years of fire fighting ops, you simply are NOT qualified to to comment on this subject. No matter how good your intentions............

Delta, I agree that the big aircraft can make a mess but would have to disagree in your comparison between the Erickson Aircrane and the DC10. They are very different tools designed for very different uses in aerial firefighting. A load dropped from a DC10 dropped correctly (ie at the correct speed and height) will not cause widspread destruction. Any drop from a Fixed Wing if done correctly must reach terminal velocity before it reaches the tree canopy and therefore should largely come down like rain. A lot of people incorrectly believe that the load needs to be "punched" or pushed through the canopy - this is when it gets dangerous.

I think the Aircranes are a great tool and I reckon that they have probably been the best single thing that has made a significant difference to the success of some of the initial fire attack in Victoria. I have, however been in the situation a couple of times as a firefighter not too far from Melbourne where the Cranes have had way too far to go for water and their effectiveness dropped significantly. Not many people know it but often on a hot day they will only be carrying about 4500 - 5500 litres. In these situations a drop from a big bomber (or several split drops) would have been far more efficient and effective without any safety issues for the crew or the guys on the ground.

SgtBundy

If the large aircraft have issues fighting close to housing or fire crews, is there any way they would be more effective in attacking fire in more remote areas before it gets on top of a town? Acting to try and direct the fire earlier or prepare an area in front of the fire to slow it down?

Just asking - no idea of the realities behind this.

Chinbu has hit the nail on the head. The most cost and time effective delivery of retardant to either a fire front or a containment line is the single engine air tanker (SEAT). They have constantly proven themselves in the face of the C214's, DC10, Convair's, etc.

These aircraft are the present and future of Australian aerial firefighting, in conjunction with their rotary winged friends. The trials of the DC10, etc, have been expensive and unsuccessful political stunts.

Nothing compares to the CL415's.

the convars are used allot in Canada and USA (so are the CL415's !!!)

Will Oz every get their heads out of the sand?

So the whole of USA,Canada and Europe is wrong in using a combination of large and small fixed wing and rotors and we are absolutely right?

Yes. That's what suits our terrain, surface water availability, and population distribution. All of these credentials are unique to Australia in their current form and equally determine the combination of aircraft and their management that best suits our environment.

So we will not see a repeat of the destruction caused by fires of the scale we have seen in recent years?

Well, that's only guaranteed by those managing the fleet. As was the case on Black Saturday, The aircraft available (Including two medium fixed wing bombers) were not utilised to any advantage at all.

Black Saturday is hardly an example of mismanaging the fleet.

With winds that strong, and thermals from the fire, flying low enough and bombing effectively is just about impossible. The wind blows the water into a fine spray/ vapour which evaporates before it hits the ground. WOFTAM.

I dont see any difference in our terrain,vegetation and summer weather conditions to that in south west coast USA or the Med countries. Lots of dry landscapes, gum trees and sea in all those places too but we persist in thinking that we are unique.

The convair "tests" also occured during some of the wetest seasons on record. I am sure they were able to demonstrate their capabilities in full sitting on the ramp with no fires to fight.

Also the remark about SEATs "flying in the face" of the large tankers / scoopers refers to the idea that there is some kind of competition. What you don't seem to understand is that these aircraft work together in a bigger picture and here in Australia we are missing a large piece of the puzzle.

While we can do without the heavy equipment in most situations, when they are needed they are an invaluable tool that we are missing.

What you are talking about is litres per hour.

You can't reduce the dump rate?
In any of the machines the rate at which the water is dumped can be regulated, combine that with the height released and you can get anything from a deluge in a concentrated area to soft rain over a wide area.

Lucerne is basically correct, we do have a system that works fairly well when properly tasked, the SEAT is an effective tool when correctly used. the large helos are a very good complement to the SEAT fleet, and this is supported by a large number of call when needed SE FW ACFT.

Our topography, geography, water resources, population quantity and density, our vegetation is all different to most of the USA that i have visited. this is not to say that large tankers can't technically work, but our current SEAT system is flexible and versatile and is highly cost effective for our little bit of paradise.

Ultimately it is the ground based assets that do the hard work and the aerial fire attack fleet assist them as much as possible, again when tasked properly.

I have flown SEAT and have spent time in the US visiting fire bases, including CALFIRE at mcClellen in Sacramento. rows of converted P3s P2s C130's and firecats, even 747 with OV10 bird dogs and again rows of kingairs.

if anyone really REALLY thinks that one convair is going to be effective when california alone has all of that inventory of aircraft, as well as numerous super well equipped fire bases capable of loading eight or ten large tankers AT THE SAME TIME, then you are sadly deluded. the USFS and other departments tip many times more into their fire suppression fleet than we do, so can support this huge aerial armada. just the CALFIRE base in sacramento makes our air force look pathetic in comparison.

No doubt the whole debate will start again soon with summer on the way, but here in Vic the government has slashed fire fighting funding on the basis that we are unlikely to have as bad a season as during the drought, so on that basis alone i cannot see a significant investment in aerial firefighting assets in the immediate future.

May 2012 "...AL-QAEDA has named Australia as a prime target for terrorism by firebombing in an online terrorism and bomb-making magazine..."
Oct 2012 "...Al-Qaeda has been blamed for a recent series of forest fires across Europe, as the head of Russia's Federal Security Service claimed they were set by arsonists as part of the group's low-cost attack strategy..."


From the thread that has just been closed

Would very likely have some relevance to the size of the firefighting fleet, especially after what appears to have been happening in Europe.

What does this have to do with Australian civil aviation?


Hmmm... seems some think terrorism and/or bush fires have nothing to do with 'civil' aviation..:confused:

All 'civil' pilots have an ASIC - Whys that ? ...Do pilots have to report any terrorist type incidents ?


...anyway, there's one who wont be starting a bush fire any time soon:

A couple of weeks ago, 26/9/12 "A man accused of terrorism offences has made an unsuccessful bid for bail at the Melbourne Magistrates Court.
The court heard on Tuesday that Adnan Karabegovic, 24, from Officer, called Australians "dirty convict pigs" and had a formula for making bombs.
He was arrested as a result of counter-terror raids in Melbourne two weeks ago...
...The court heard telephone intercepts recorded Karabegovic talking about going to Bosnia to train and using bombs to start bushfires..."

It's a shame that the VIC government think that way. It is that kind of thinking that will create a pathway to another "Black Saturday". There is much more potential for disastrous fire incidents at the moment when compared with times of drought due to the intense levels of fuel available. When this summer is in full swing, watch the DSE incident page and just see how much risk there is. We are certainly rubbing our hands together for the coming season. It has already started in NSW where we have already flown more hours than the last three seasons combined. At least we are ready!

Fires have many millions of dollars to do with Australian Civil Aviation. Where do some of these moderators come from????

The DC-10 always struck me as a political knee-jerk reaction in order to give the impression of taking action following the Black Friday bushfires in 2009 , and no they never dropped in anger in Victoria , only some pattern testing around Fiskeville from memory in order to obtain some impressive PR footage .... they've been bombing fires O/S for years so hardly needed more testing .

Aerial fire fighting is a very State based system , with each state running their own individual program and mix of fixed / rotary wing fleet on contract plus others on adhoc/standby , then operating said fleet in a most Government-like way , which is to say it's run by OH&S lawyers which usually destroys any hope of real productivity .

Plenty of good people flying the various machinery tho'.

Oh and very well said Harley D as usual.
