  Les futurs avions de chasse canadiens pourraient subir des modifications dictées par les Américains

  La Presse canadienne Le plus haut responsable de l'approvisionnement militaire au Canada affirme que les prochains avions de chasse des Forces armées canadiennes pourraient subir des modifications pour être certifiés selon les normes américaines, mais il ne s'inquiète pas d'une possible ingérence politique des États-Unis. Correction : Dans une dépêche transmise vendredi, La Presse canadienne avait erronément rapporté que les États-Unis devraient approuver tout achat d'avion de chasse par le Canada. En réalité, le Canada peut acheter le modèle qu'il veut, mais l'appareil choisi pourrait subir des modifications pour être certifié selon leurs normes. Patrick Finn, sous-ministre adjoint du Groupe des matériels du ministère de la Défense nationale, a fait savoir que les États-Unis devaient certifier que l'avion de combat choisi par le Canada est conforme aux normes de sécurité américaines. En effet, quel que soit l'appareil qui va remplacer les vieux CF-18, il doit être compatible avec le réseau de renseignement le plus sécurisé des États-Unis, qui vise à protéger l'Amérique du Nord par l'entremise du Commandement de la défense aérospatiale de l'Amérique du Nord (NORAD). Le NORAD utilise un réseau de satellites, de radars basés au sol, de radars aéroportés, ainsi que des avions de chasse pour détecter et intercepter les menaces aériennes visant le Canada et les États-Unis. Des représentants de l'industrie craignent que cette obligation serve de prétexte aux États-Unis pour empêcher le Canada d'acheter les modèles Eurofighter Typhoon ou Saab Gripen, fabriqués par des sociétés européennes. Ces entreprises sont des concurrentes des constructeurs américains. Ces inquiétudes sont particulièrement vives en ce moment, étant donné l'attention particulière qu'accorde l'administration du président Donald Trump à la vente de produits américains à des pays étrangers. Bien qu'il soit incapable d'exclure entièrement ce risque, Patrick Finn indique que cette certification ne sera nécessaire que dans plusieurs années, et que des responsables américains ont déjà manifesté leur ouverture à l'achat d'avions non américains par le Canada. https://ici.radio-canada.ca/nouvelle/1169226/futurs-avions-chasse-canadiens-approbation-washington

  COVID-19 prompts purchase of new medical transportation system for RCAF aircraft

  David Pugliese • Ottawa Citizen The Canadian Forces is hoping to purchase what it is calling an aeromedical bio-containment evacuation system that can be outfitted on its C-17 or C-130J aircraft. The equipment, also known as ABES, will be capable of transporting highly infectious disease patients on the aircraft. The Royal Canadian Air Force is looking to have these delivered to 8 Wing Trenton, Ontario by Oct. 31, 2020, said Department of National Defence spokesman Dan LeBouthillier. “This project is in support of federal efforts to assist civil authorities and non-governmental partners in responding to major international and domestic emergencies,” he explained. “As required, this acquisition will provide the whole of government approach with additional tools to respond to the COVID-19 pandemic.” He noted the Canadian military already has interim capabilities in this area as the RCAF can transport a patient with a highly infectious disease in a specialized isolation unit by aircraft. “The ABES will enhance our ability to move more patients much more efficiently over a longer distance,” he noted. The ABES must be able to accommodate a minimum of four patients, according to the industry notice the federal government put online. The RCAF is also interested in acquiring additional isolation units to supplement those that will be available through the ABES. The units will be able to be transported by the majority of RCAF aircraft and will consist of individual, hard-shell, durable isolation units that can be reused by the Canadian military as well as lightweight, single-use isolation units. https://ottawacitizen.com/news/national/defence-watch/covid-19-prompts-purchase-of-new-medical-transportation-system-for-rcaf-aircraft/

  UAVs remain a persistent problem around Canadian airports

  by Ken Pole Transport Canada data on unmanned aerial vehicles (UAVs) flown in or near controlled airspace in 2018 show that this remains a persistent problem, even as the federal government continues to work on updated regulations. Interim regulations in effect since last May prohibit UAVs inside controlled or restricted airspace, and require them to be flown at least 5.6 kilometres away from any area where aircraft take off or land. These regulations also require unmanned aircraft to be at least 1.9 kilometres away from heliports. UAVs must be flown only during daylight hours, always in line of sight, below 90 metres above ground level (AGL), and at least 30 to 76 metres from vehicles, vessels and the public. The only exception is for operations from a field or an event approved by the Model Aeronautics Association of Canada. Last summer, Transport Canada initiated two pilot projects involving emergency responders and several private companies which operate UAVs beyond visual line-of-sight (BVLOS) in an attempt to collect safety information to help regulators understand the challenge. “Transport Canada has indicated that they have now completed a few operational tests and will continue their trials,” wrote aviation lawyer Auriol Marasco, a partner in the Toronto law firm Blake, Cassells & Graydon, in a Jan. 3 website article. “The industry is anxiously awaiting the results as they will provide key indications as to how the BVLOS operations will be regulated.” Marasco also said Transport will be releasing updated regulations for UAV operations within visual line-of-sight (VLOS). Updated rules were expected by the end of December, but a Transport Canada spokesperson told Skies in a Jan. 4 email that the department “continues to work on getting the final regulations published . . . as soon as possible in 2019.” Meanwhile, the department's Civil Aviation Daily Occurrence Reporting System (CADORS) for last year–which could be amended as any year-end reports are incorporated–includes at least 123 reports involving UAVs not in compliance with the regulations. In some cases, the UAV was close enough for pilots to identify the make, model, and even estimate its weight. All major scheduled and charter carriers have filed reports about encounters at various altitudes, some within close proximity to runways. In June, the crew of an Air Inuit Boeing 737 on final approach 3.7 kilometres from Montreal/Pierre Elliott Trudeau Airport reported an orange UAV at some 360 metres AGL. At the same airport three months earlier, the tower advised an aircraft taking off that there was a UAV approximately 900 metres from the runway threshold at about 200 metres AGL. Quebec accounted for “only” eight CADORS reports in 2018. Given their traffic volumes, Ontario, British Columbia and Alberta topped the list with 48, 37 and 16 reports, respectively. One of the B.C. reports came from the crew of an Air Canada Airbus A321 on final approach to Vancouver International Airport. Descending downwind, they reported a UAV “whizzing by” at approximately 7,000 feet AGL. In another notable incident, the Vancouver Harbour Flight Centre (VHFC) reported a UAV some 200 feet above the floatplane docks as a Seair Seaplanes aircraft was taxiing out for departure. The only other detail provided in the CADORS was that “the UAV operator was located and counselled by a VHFC representative” and that the UAV had been landed. Reports were filed by commercial, corporate, private and military fixed-wing and helicopter pilots as well as members of the public. In most cases, the CADORS notes “no impact on operations.” However, that wasn't the case last February with a Cessna 172S registered to B.C.-based Chinook Helicopters. On a training flight from Abbotsford to Chilliwack, as it turned on right base to Chilliwack, the pilot reported that the leading edge of his left wing had been struck by an unknown object. He landed without further incident and police were advised. No UAV debris was found but blue paint was evident on the Cessna's damaged area. It was a situation that clearly could have been much worse. https://www.skiesmag.com/news/uavs-remain-a-persistent-problem-around-canadian-airports
