  Unmanned SkyGuardian to cross Atlantic for RIAT debut

  BY: CRAIG HOYLE General Atomics Aeronautical Systems' MQ-9B SkyGuardian medium-altitude, long-endurance remotely-piloted air system (RPAS) will make it first transatlantic journey early next month, before appearing at the UK's Royal International Air Tattoo. The aircraft – which forms the basis for the UK Royal Air Force's future Protector RPAS – is scheduled to land at RAF Fairford in Gloucestershire on the evening of 11 July, and is due to appear in the static display at the 13-15 July RIAT event. Expected to last more than 20h, the non-stop sortie will commence from General Atomics' flight-test and training centre in Grand Forks, North Dakota. On 25 June, the UK Civil Aviation Authority detailed a series of planned airspace restrictions that will be made in support of the SkyGuardian's arrival. These will be activated "for the safety of the remotely-piloted aircraft and other airspace users", it says. "Temporary danger areas will be activated by NOTAM with potentially less than 24 hours' notice," the CAA says. "Each danger area will be managed by an air traffic control unit." During flight testing, the SkyGuardian has demonstrated its ability to remain airborne for more than 48h. "The civilian aircraft, which is certificated and registered through the US Federal Aviation Administration, has been issued permission to operate within UK airspace," the CAA says. RAF operations with at least 20 Protector RG1s are due to commence during the 2020s, with the type – to be certificated for use in non-segregated airspace – to replace the service's current armed Reapers. https://www.flightglobal.com/news/articles/unmanned-skyguardian-to-cross-atlantic-for-riat-debu-449768/

  New Tool Developed to Improve Pilot Visibility

  8/14/2020 By Connie Lee Special Operations Command and the Army are adopting new technology to improve visibility during flight operations in degraded conditions. Sierra Nevada Corp. was selected for the third phase of the degraded visual environment pilotage system competition following a 2015 airborne test. The company's most recent contract modification includes full-rate production, according to a company news release. Paul Bontrager, Sierra Nevada's vice president for government relations, said the system will help pilots operate in areas with limited visibility such as fog and dust. “We've always had a hard time flying in snow and flying in dirt,” he said. “In Army aviation we've been waiting for this technology to mature, and it has.” To enable pilots to maintain their situational awareness, the product has multiple features such as cameras and radars, he said. The system also has light detection and ranging. By combining sensors, a pilot is able to see a more accurate picture of the surrounding environment. Additionally, there are different versions of the system with varying amounts of sensors, he noted. Sierra Nevada can take data from multiple sensors and fuse the imagery onto a screen, he said. “A camera can do so much,” he said. “But then a lidar can actually paint the landing area and give a lot of detail about the surface.” The military has often had to fly in challenging operating environments, he noted. In the Middle East, pilots would often experience “brown out,” which occurs when visibility is impacted by dust and sand which has resulted in crashes, he said. “When we got embroiled in the wars in Iraq and Afghanistan, it was a significant thing,” he said. “We actually had more losses in the more recent years when it wasn't direct combat operations. We have more losses annually due to flying into planet Earth unintentionally than we do from enemy fire.” The degraded visual environment pilotage system is likely to be used in Army Chinooks and Black Hawks, and any aircraft with lifting capacity, he noted. “These are aircraft that have to land and take-off ... in all environments,” he said. “This is where it's most likely to be used initially ... and hopefully all aircraft will be outfitted with this technology eventually.” https://www.nationaldefensemagazine.org/articles/2020/8/14/new-tool-developed-to-improve-pilot-visibility
