Quebec’s CL-415s helping out in Fort McMurray

On May 5th, 2016, according to what had been announced by the Government of Quebec, four CL-415s took off from the Quebec Jean-Lesage international airport (CYQB) heading to Fort McMurray, Alberta, to help in the fight against widespread forest fires in that province. It is the worst natural disaster that Canada has known in its history.

Preparing flight crews and aircrafts for such a long cross-country trip naturally demands much coordination from the SOPFEU (Society for the protection of forests against fires). Once they will have landed at the Fort McMurray airport, the pilots of those CL-415s will be under the direct command of the Albertan authorities in charge of fighting the wildfires, since the latter are best positioned to know exactly what the local needs are.

I figure that the flight service specialists (FSS) of the Nav Canada flight information center (FIC) in Edmonton must have quite busy days with the increased aerial activity associated with the numerous fires…

The picture above shows crew members heading towards their assigned aircraft. Once they start working in the Fort McMurray region, they will not only have to directly fight the forest fires but also head to sectors that have not yet been touched by fire and water the area thoroughly to prevent new wildfires.

Taking pictures of propeller-driven aircrafts

It is a bit touchy to photograph propeller-driven aircrafts while making sure that there is a sensation of movement. In a natural reflex to want to avoid blurred pictures, the photographer uses a shutter speed that corresponds to the focal used for the shot. In the case of the picture above, the focal was 400mm. But if a shutter speed of 1/400 had been used, the propellers would have been totally immobilized and the aircraft would have looked like its climbing while not using its engines.

It was necessary to reduce the speed to 1/160, thus increasing the risk of obtaining a blurred picture. In order to get both image sharpness and moving propellers visual effect, the photographer has to follow exactly the movement of the aircraft with the camera so that it looks totally immobile in the viewfinder. This asks for a bit of practice but allows for more realistic photos.

The government of Canada helping out Alberta’s citizens

The government of Canada, under Justin Trudeau, has promised to match the amounts of money offered by all Canadians to the Red Cross society toward helping the Fort McMurray population.

Obviously, its contribution will not stop there (in fact, far from it), but the message is for the whole Canadian population to contribute generously to support the efforts of the Red Cross. It is already estimated that the material damages will reach at least nine billion dollars and that numerous years will be required to rebuild everything. The Liberal Party of Canada had built its political campaign around the need to invest for the renewal of infrastructures. With the Fort McMurray fires, there will be plenty of new unplanned expenses ahead.

More than 1,400 firemen are fighting the wildfires. So few, there has been very few lives lost, although “very few” is always too much. The crisis is, according to everyone, well managed by the government of Alberta.

At the time of writing, there was still no rain forecasted for days to come and the drought was also extending to the southern half of Saskatchewan and part of Manitoba. The winds were expected to increase, which would mean that even more resources would be needed in the near future to bring those wildfires under control.

It seems to me that the government of many Canadian provinces would benefit in acquiring new water bombers like the CL-415 to give them an increased margin of manoeuver that would allow them to react more quickly, if we take into account the tendency for the ever growing number and size of forest fires. In the picture below, the government of Quebec CL-415 number 247 is just airborne from Quebec to Fort McMurray.

The CL-215s will not head to Fort McMurray

While several CL-415s are leaving for Alberta, few water bombers, like the two Canadair CL-215s shown below, stay at the Quebec Jean-Lesage international airport in case of forest fires in the province and also to be used for the seasonal rehearsal needed for every pilot before they are dispatched across the province of Quebec.

Global warming

Some people can say that global warming is not responsible for the increasing number of extended wildfires. They might be right, but I prefer to adopt a wider view than only what is going on in Alberta. Heat transfer between the north and south are now more extreme in order to equalize the temperatures around the globe. All means to reduce the difference in temperatures between the equator and the poles are at work and this causes increasing problems to particular regions.

A powerful El Nino phenomenon, repetitive Omega blocks, the air circulation in different cells (Hadley, Ferrell, polar, Walker) all participate in the heat exchange. At a more reduced scale, we also regularly hear of cold and warm fronts in the meteorological forecasts.

It is certainly not local warm fronts that are responsible for the fact that a thinner layer of permafrost is unable to ensure the stability of Arctic runways anymore. Nor are fronts responsible for the fact that houses on stilts do not have a stable foundation anymore. Many heat records have been established these past years in northern Canada. There will certainly be large amounts of money to spend to rebuild the Nordic infrastructures.

Brush fires as soon as April in Alberta

This year, as soon as April, there were widespread brush fires in a region as north as Fort McMurray in Alberta because winter has not brought much snow to humidify the land during Spring. I thus wondered what would happen once in July. Albertans did not need to wait that long to get the answer.

The modelization of climatic changes indicates that, in the Fort McMurray region, the forest fire season is already fifteen days longer that it used to be. More heat might favor more droughts. But an increase in temperature also favors the development of thunderstorms and with them comes lighting that will start up new fires.

One thing is sure: insurance companies will not lose time with the different theories on global warming. The reinsurers (those who insure the insurance companies) have the obligation to limit their losses to stay afloat and premiums will quickly increase to answer to the thousands of claims following an increasing number of natural disasters.

Photos of the local air traffic in Quebec, just after the CL-415s departed to Fort McMurray

At the Quebec airport, between the take offs of the four Bombardier CL-415 towards Fort McMurray, I was able to take few pictures of the local air traffic. In the photo above, it is possible to see a FedEx ATR 72 (C-FTAR) taxiing toward the ramp after a landing runway 06. An Air Canada Express Bombardier DHC-8-402 (Q-400) (C-GIJZ) was also being towed for is imminent departure.

ATAC’s Hawker Hunter N339AX

Being in luck, I was able to capture a Hawker Hunter (N339AX) belonging to the American company  ATAC, just airborne from Quebec. As for any military jet, it is difficult to ignore them on take-off: the reactor’s noise is there to remind you of their presence…

The pictures above have been taken with a Canon 5D MKII camera, equipped with a telephoto lens Canon 70-200 f2.8L IS II USM with a polarizing filter and a Canon Extender EF 2X III which brought the focal length to 400 mm. Even then, more cropping was necessary to enlarge the aircraft since I was quite far away from the runway.

Wishing to ensure that the image was sharp (a blurred picture is more probable with a 400 mm focal length while the photographer attempts to follow a fast flying jet), I adjusted the shutter speed to 1/1600 and made sure that the automatic focus was set on AI servo.

I now realized that a slower speed could have worked a bit better since it would have allowed showing a blurred forest in the background while keeping the aircraft sharp. But it is not often that you have the opportunity to see a Hawker Hunter in flight these days and I played safe with the shutter speed. The ideal shot will be for another day…

CL-415s and CL-215s together in Quebec (2012 photo)

A last picture, taken few years ago, during autumn 2012, shows numerous water bombers CL-415 and CL-215 parked at the Quebec Jean-Lesage international airport (CYQB). During the off- season, the water bombers are brought back to Quebec City from the different bases were they have been in operation during summertime.
