  Simulating the ‘SuperScooper’

  by Lisa Gordon The Viking CL-415 “SuperScooper” is more akin to a pick-up truck than a sports car. It's a hardworking, amphibious turboprop that was built to fight wildfires. It flies low, battling blistering heat and blinding smoke, before releasing 13,500 pounds of water in six seconds – and then returning to a nearby lake where it skims the surface to reload. Introduced in 1993 by Bombardier, the CL-415 was essentially a turboprop version of its predecessor, the piston-powered CL-215. Today, there are close to 170 CL-215/415 aircraft in operation, mostly in Europe and North America. They are now supported by Viking Air, which acquired the program from Bombardier in 2016. Pilot training in the CL-415 has historically been done in the aircraft, but TRU Simulation + Training says that due to the unique mission it performs, those training flights can be dangerous. The South Carolina-headquartered company is a division of industry giant Textron Inc., and was formed following the amalgamation of several specialty flight simulation and pilot training companies, including former Montreal-based Mechtronix. About two years ago, TRU's commercial aviation division in Montreal began designing the world's first CL-415 full flight simulator (FFS) with the capability to replicate operations not only in the air, but also on the water. The company was able to draw on its recent experience of successfully building a Series 400 Twin Otter FFS for Canada's Pacific Sky Aviation in Calgary, Alta. – the world's first seaplane simulator with water-handling capabilities. “Before the Twin Otter project, hydrodynamic modelling is something we hadn't done before,” acknowledged Thom Allen, TRU's vice-president of Technology and Innovation. “It's like a boat simulator because you're modelling the buoyancy of the floats or the fuselage in the water. Interestingly, our engineers working on the Twin Otter program actually went to the library and researched how boats work on the water. Mixing the boat sim with the aerodynamic sim is the whole package.” He said the CL-415 experience took things one step further by adding the mission component – scooping the water – to the Twin Otter build. “From a safety point of view, the types of missions you do in a waterbomber are quite a bit different from a commercial aircraft. When you're scooping water and dropping it over a fire, training in those conditions is very dangerous. The tradeoff has always been between the quality of the training and the danger of doing that sort of training.” TRU's CL-415 FFS was delivered to Ansett Aviation Training in Milan, Italy, in September 2018 and certified by the European Aviation Safety Agency (EASA) in December to Level D standards. Although training courses have yet to be completed in the simulator, the hope is that both initial and recurrent pilot training will be done exclusively in the device. Allen said the operational characteristics of a CL-415 are complex and unique. “When you're flying over a very hot fire, you drop your water and the mass of the aircraft is cut in half. The turbulence effect is quite significant when you hit the updraft. The fire is creating turbulence, smoke, reduced visibility – and pilots are dropping every five or 10 minutes repeatedly, usually in rugged terrain at low altitudes. This is the part that made this project something new.” To gather accurate performance data, TRU rented a CL-415 and equipped it with flight test instrumentation. “We weren't doing fire drops with our engineers on board, but we did all the manoeuvres around that, and we brought in a number of senior CL-415 pilots to evaluate our work.” The result is the world's first high fidelity CL-415 simulator with the capability of replicating not just air and water operations, but various types and intensities of forest fires and changes in related environmental conditions. The cockpit noise level is accurately reproduced by a secondary audio system that – like the real aircraft – requires crewmembers to wear a noise-cancelling headset.

  What is 'the backbone' of the Canadian Army doing in a junk yard?

  Colin Butler Even an expert in armoured fighting vehicles thinks it's a strange place to find what the Canadian Army calls "the backbone" of its combat vehicle fleet. "I'm surprised that vehicles of this importance and significance are being stored in a conventional steel breaker's yard," said Jon Hawkes, the Land Management Editor for military information publisher Jane's Information Group. "Typically they'd be in a military facility of some kind, even if it's sort of, you know, popped out in the back out of the way in the contractors own facility." "For them to be in this breaker's yard is not where I would expect them to be." "Them," in this case are the LAV III, the workhorse of the Canadian Army. You've likely seen them on television, either helping Canadians stricken by some natural disaster, such as the 2013 floods in Alberta, last year's floods in Quebec, or, maybe overseas, carrying our troops into hot zones in such places as Afghanistan and more recently Mali. What are these LAV IIIs doing in a junk yard? So what on Earth are they doing in the back lot of a junk yard? "I think it's interesting," John Hawke said. "You could read that two ways." "On one hand, these things are being quasi-dumped in a corner somewhere to be dealt with later and perhaps that's not caring for them in the best possible way. Although as I say, they're very hardy vehicles. I wouldn't necessarily fear for their status." "Alternatively you could say that someone somewhere is actually being quite smart in finding a very cost-effective solution for storing them for a period of time. I'd imagine it's not hugely expensive to put them wherever this is." Secretive contractors Except, no one working with these LAVs is willing to talk. CBC News first attempted to visit the site in person, but was told to leave the property by staff at the scrap yard. When contacted by phone, Matt Zubick, a member of the family that owns John Zubick's Limited said "I can't talk about that" before he hung up. Steph Bryson, a spokeswoman for General Dynamics Land Systems Canada, declined to comment, referring the question to the Department of National Defence. So why all the secrecy? No secret at all "I find that a bit amusing," said Daniel Le Bouthillier, the head of media relations for the Department of National Defence. "From our perspective, the work is hardly a secret." It turns out the work inside John Zubick's Limited has been happening for the better part of a decade. After Canadian troops deployed in Afghanistan, they quickly realized the army's fleet of LAV IIIs, which they've had since 1997, needed a few tweaks to give soldiers better protection against the Taliban insurgency. Those tweaks involved better armour, blast absorbing seats and other upgrades. However, the LAV IIIs were never designed to handle the extra weight, according to Le Bouthillier. "This additional weight meant more wear and tear and affected the vehicles' what they call 'full mobility potential.' So these upgrades that are happening now address all those issues." The upgrades are being done by London, Ont.-based military manufacturer General Dynamics Land Systems Canada as part of a $1.8 billion refitting and refurbishment program with the Canadian Armed Forces called LAVIIIUP, a deal that was first struck in 2010. The program will see all 550 Canadian-made LAV IIIs, getting new armour and new hulls in order to extend the life of the vehicles until the year 2035. "As part of that process, LAV III hulls, which were not designed to support the weight of upgrades are being sent to a scrap yard, taken apart and melted and this is done because these are considered controlled goods," Le Bouthillier said. "So what you're seeing in that scrap yard are parts that are not being harvested for the upgrades," he said. "These are not drive-in, drive-out full capability vehicles. These are just parts of them. They might look like full vehicles because they're so big. Especially when you look at them from above." The first batch of upgraded LAV IIIs were delivered to the military in 2012, with the delivery of the final batch expected next December. https://www.cbc.ca/news/canada/london/london-ontario-lav-1.4734920
