  RCAF working toward new sniper pod placement on CF-188 Hornet

  Chris Thatcher In a two-by-three metre wind tunnel at the National Research Council of Canada's (NRC) aerospace research centre in Ottawa, aerospace engineers are gathering data for the Royal Canadian Air Force (RCAF) this week to validate the placement of the sniper pod on the centreline station of the CF-188 Hornet. “For this configuration, we are running at close to takeoff and landing speeds to simulate the take off and landing of the F-18, about 100 metres per second or almost 200 knots,” explained Melissa Richardson, an aerodynamics research officer and the project manager for the testing process, as wind whipped over the inverted nose landing gear and sniper pod. The CF-188 fighter jet has carried a certified sniper pod on the left side of the fuselage, below the engine intake, since the aircraft were upgraded in the early 2000. But lessons from recent operations over Libya in 2011 and Iraq and Syria between October 2014 and March 2016 convinced pilots they would have a better view of possible targets with the centerline placement. “We found a lot of our missions revolved around looking at the ground, monitoring areas of interest and targets for missions that are four to five hours long,” said Capt Tom Lawrence, a CF-188 pilot and the project officer for fighter weapons and equipment. “When [pilots] are manoeuvring their aircraft, there is a chance of the aircraft actually masking the targeting pod. Putting [it] on the centre of the aircraft allows a larger field of regard.” Rather than bank left to maintain focus on a target, the new placement should ensure an uninterrupted view of the ground or target aircraft, “taking that frustration out of the pilot's mind,” he said. “They can just focus on the imagery and the task at hand.” Lawrence said it could also make it easier for pilots to employ weapons and assess battle damage effects. The purpose of the wind tunnel tests is to measure the aerodynamics created by the nose landing gear on the sniper pod mounted behind it at times when it is most exposed to turbulence, said Richardson. Among concerns before the tests began were the effect of significant vibration on the pod and the possibility of debris being kicked up by the wheels and striking its protective glass shield. “[We need to] make sure the aircraft is safe to operate with the sniper pod on this new location. That means it can take off and land without excessive vibration, that the loads are still within acceptable limits,” explained Capt David Demel, the certification authority with the RCAF's Technical Airworthiness Authority. “This is the goal of the current wind tunnel test, to confirm that before we move to the flight test phase in Cold Lake in the September timeframe.” A second a high-speed equivalent test will be conducted by the NRC at its high speed trisonic wind tunnel in about three weeks, using a six per cent scale model, that will include ensuring engine intake airflow is not affected. Test pilots with the Operational Test and Evaluation Unit in Cold Lake will then recertify operational airworthiness of the sniper pod in its new placement. While the testing facilities are being provided by the NRC, the vibration data is being gathered and analyzed by Bombardier, which has provided some of the instrumentation. The sniper pod and landing gear were installed in the wind tunnel by L-3 MAS, which will have the task of mounting the pods in the new location on the entire CF-188 fleet–including the 18 F/A-18 Hornets the government is negotiating to buy from the Royal Australian Air Force–once approved. “We're all collaborating on the project as it goes through each phase, from technical airworthiness to operational airworthiness,” said Lawrence. https://www.skiesmag.com/news/rcaf-planning-new-sniper-pod-placement-cf-188-hornet/

  Federal government to buy two more Arctic ships from Irving to prevent layoffs

  By Lee Berthiaume, The Canadian Press OTTAWA — Prime Minister Justin Trudeau is expected to announce Wednesday that the federal government is buying two more Arctic patrol ships on the top of the six it has already ordered from Halifax-based Irving Shipbuilding. However, unlike the first six ships, which are being built for the navy at a total cost of $3.5 billion, a government source said the seventh and eighth will be built for the Canadian Coast Guard. The source, who was not authorized to comment publicly, said the move is intended to address the Canadian Coast Guard's desperate need for new ships. Documents obtained by The Canadian Press earlier this year warned that more than a third of the coast guard's 26 large vessels have exceeded their expected lifespans — and many won't survive until replacements arrive. And that advanced age is already affecting the coast guard's ability to do its job, including reduced search-and-rescue coverage, ferry-service disruptions and cancelled resupply runs to Arctic and coastal communities. The second problem is the threat of layoffs, which Irving has long warned will happen unless the government fills a gap between when the last Arctic patrol ship is finished and construction on the navy's new $60-billion warship fleet, the source said. The government sought to address that gap in November when it ordered the sixth Arctic patrol vessel for the navy from Irving and agreed to pay the shipyard to slow production for a total cost of $800 million. Government officials at the time defended the high cost of that move, saying a third-party assessment commissioned by the government, which has never been made public, indicated it would cost even more to allow a gap to persist. "Ultimately what happens is the workforce gets laid off, you rehire people, it's not the same people so you're retraining, and then you have this learning curve," Patrick Finn, the Defence Department's head of procurement, said in January. "From some of the data we've run, doing what we've done, if we don't do it, we're probably going to pay that much money anyways in inefficiencies and get nothing for it. So the analysis shows that this is really a prudent way forward." Even then, federal bureaucrats and Irving both warned more would need to be done as even with those measures, there was still the threat of an 18- to 24-month gap between construction of the two fleets.

  AU CANADA, LES POLICIERS VONT UTILISER LES RÉSEAUX SOCIAUX POUR PRÉDIRE LES DISPARITIONS AVANT QU’ELLES NE SE PRODUISENT

  Avec une base de données suffisante et une intelligence artificielle, il est parfois possible d'anticiper certains incidents. Certaines plateformes, comme Facebook, travaillent sur des algorithmes permettant de repérer les adolescents suicidaires et d'intervenir dans le cas où ils risquent de passer à l'acte. Au Canada, les forces de l'ordre vont utiliser des modèles prédictifs pour prédire les disparitions avant qu'elles n'aient lieu. Selon un rapport du gouvernement, les modèles prédictifs seront basés sur des publications sur les réseaux sociaux, les dossiers de la police et les services sociaux. Les algorithmes se référeront à une dizaine de facteurs de risques communs, comme des antécédents de fugue ou de violence à la maison, afin d'identifier les personnes susceptibles de disparition. L'initiative fait toutefois l'objet de nombre de critiques. Certains experts pensent que l'utilisation de modèles prédictifs à cette fin pourrait conduire à de faux positifs. Le type d'informations à utiliser n'a pas été dévoilé Le document a été publié le mois dernier par la RDDC (Defence Research and Development Canada), une agence rattachée au ministère de la Défense nationale. Selon le rapport, la conception des modèles prédictifs sera assurée par SPPAL (Saskatchewan Police Predictive Analytics Lab). Ce laboratoire est le fruit d'un partenariat entre la police, le ministère provincial de la Justice et l'Université de la Saskatchewan. La police canadienne utilise déjà les réseaux sociaux pour repérer des cas d'infraction, trouver des suspects et résoudre des enquêtes. Toutefois, le rapport n'indique pas les types d'informations qui seront recueillies sur les médias sociaux. Des risques de faux positifs Tamir Israel est avocat à CIPPIC (Canadian Internet Policy and Public Interest Clinic). Il a reconnu que les modèles prédictifs de SPPAL pourraient être utilisés pour trier les cas suspects selon leur ordre de priorité. Il est en effet nécessaire de distinguer, par exemple, une éventuelle victime d'enlèvement d'une fugueuse habituelle. « Les forces de l'ordre seront invitées à s'appuyer sur les résultats du modèle prédictif » pour décider de la sérieuse prise en charge d'un cas de personne disparue », a-t-il déclaré à Motherbord. Toutefois, il a souligné que ces modèles prédictifs sont souvent opaques dans leur fonctionnement, en s'appuyant sur des facteurs que les policiers eux-mêmes ne peuvent pas évaluer ou deviner. Il a noté que les informations sur les réseaux sociaux ne sont pas toujours fiables et augmentent les risques de faux positifs. Il a également noté que cette méthode pourrait conduire à des résultats faussés lorsque les modèles sont appliqués à des groupes minoritaires. Il craint qu'ils ne fassent pas de différences entre les cultures. « Nous savons que les modèles prédictifs sont loin d'être infaillibles dans des situations réelles et qu'il y aura des faux positifs », a-t-il rappelé. « Les conséquences d'une intervention basée sur un faux positif peuvent être très graves. » http://www.fredzone.org/au-canada-les-policiers-vont-utiliser-les-reseaux-sociaux-pour-predire-les-disparitions-avant-quelles-ne-se-produisent-998 http://cradpdf.drdc-rddc.gc.ca/PDFS/unc335/p809812_A1b.pdf
