The plane was flying from New York's John F. Kennedy International Airport to Paris when it exploded near Long Island, killing all 230 people aboard. Terrorism was initially suspected, and a number of witnesses on shore came forward with accounts of seeing a flare, rocket or "streak of light" headed toward the plane before the explosion. After a four-year investigation, however, the NTSB determined that a fuel tank explosion - sparked by a short circuit in the wiring - caused the crash. The safety board found that witnesses were vague or imprecise in their recollections. The FBI also conducted an investigation, and it did not find evidence of a crime. In June 2013, a group called TWA Project 800 filed a petition asking the NTSB to reopen the case. The group claimed that "a detonation or high velocity explosion" was the cause, according to the NTSB. The NTSB said the group did not show that the agency's original conclusion of a fuel tank explosion was incorrect, so the petition was denied. http://www.usatoday.com/story/travel/news/2014/07/02/ntsa-twa-flight-800-inquiry/12111297/ Back to Top FAA: We're working to reduce accidents By: Peggy Gilligan The Federal Aviation Administration and the entire general aviation community have been working together for years to reduce fatal accidents in small aircraft by using data to determine the leading cause of accidents. Those efforts have focused most recently on stalls and other loss-of-control incidents, because they account for 40% of small aircraft accidents. Aircraft design contributes significantly to general aviation operations safety, but pilot awareness and decision-making will always play a key role in aviation safety, no matter how many safety features the FAA requires on an airplane. An accident finding of pilot error does not suggest that the pilot's decision-making was the only factor in an accident. But the pilot's reaction to problems that develop in flight - including maintenance issues, running out of fuel, weather and other factors - frequently makes the difference between a safe landing and a different outcome. The FAA recently made it easier and more cost-effective for pilots to install safety technology that helps them prevent losing control of the plane in flight. The aviation community also is working on improved pilot training and education to help pilots respond to the many scenarios they may face while flying. Accident data do not point to aircraft design or defective parts as a major cause of small aircraft accidents. However, the FAA has made many important safety improvements in aircraft design and standards over the years - including improvements to aircraft that were designed many years ago. The FAA mandates continual, immediate safety improvements over an aircraft's entire lifetime through Airworthiness Directives, if it determines an aircraft part, component or system is unsafe. As USA TODAY notes, the FAA also has addressed design safety issues if any develop once an aircraft is in service. The FAA currently is working on updated certification standards for small aircraft that will streamline the process to introduce new and innovative safety technology on future and existing small airplanes. Congress and industry support the effort to implement those rules as quickly as possible. Peggy Gilligan is the Federal Aviation Administration's associate administrator for aviation safety. http://www.usatoday.com/story/opinion/2014/07/02/faa-general-aviation-safety-editorials- debates/12117931/ Back to Top American Airlines flight to D/FW diverted for unruly passenger American Airlines Flight 362 from San Diego to D/FW International Airport was diverted to Phoenix Wednesday afternoon for unspecified security reasons. DALLAS -- American Airlines Flight 362 from San Diego to D/FW International Airport was diverted to Phoenix Wednesday afternoon due to an unruly passenger. American Airlines spokesman Matt Miller said the passenger was escorted off the plane in Phoenix and is now in police custody. Flight 362 now has a 5 p.m. departure time from Phoenix to Dallas. http://www.wfaa.com/news/local/American-Airlines-flight-from-San-Diego-to-DFW-diverted- 265606621.html Back to Top 4 airlines refuse to lease aircraft to PIA A source says the foreign airlines expressed their inability to lease the aircraft citing security issues. -File photo LAHORE: Four foreign airlines have refused to give aircraft to the Pakistan International Airlines (PIA) on 'wet lease' because of security reasons. The airlines of Eastern Europe and Central Asia had shown interest in providing four aircraft to the PIA when it floated a tender in early June. But after the attack on Karachi airport and firing at a PIA plane in Peshawar, they have withdrawn the offer. Under the wet lease agreement, an airline provides aircraft, pilots and cabin crew and maintenance and insurance, while under the dry lease the airline provides only aircraft. A source in the PIA told Dawn that the foreign airlines had offered to provide 180-seater A320 and 737 aircraft to PIA, but now they expressed their inability to do so citing security issues. He said the national flag-carrier was also facing problems in acquiring planes on dry lease. "PIA is facing the brunt of terror attacks on two airports and it seems that more difficult time is ahead. The government will have to extend its full support to PIA to deal with the situation," a senior PIA official said. PIA's spokesperson Mashhood Tajwar admitted that PIA was facing problems in acquiring planes on wet lease following the attack on a flight in Peshawar. "We are negotiating with some foreign airlines and are optimistic of acquiring aircraft on wet lease," he said, adding that PIA would get two planes on dry lease by September which would help stabilise its operation. "We are in the process of floating a tender for acquiring 10 planes on dry lease this week," he said. Four foreign airlines suspended their flights to and from Peshawar and one to and from Karachi after the attacks. Also see: PM expresses resolve to make PIA world's leading airline PIA's flight operation was hampered a month ago after the return of four aircraft it had acquired on wet lease in December last year from Turkish and Czech Republic airlines. After the expiry of the lease agreement with these airlines, PIA has reduced the number of its foreign and domestic flights to 26. With total 25 planes in its fleet, PIA has reduced seven flights on Dubai route, one each on Manchester, Barcelona, New Delhi, Kuala Lumpur, Dhaka, Abu-Dhabi and Kuwait and remaining on domestic routes. http://www.dawn.com/news/1116709/4-airlines-refuse-to-lease-aircraft-to-pia Back to Top FAA lab using virtual reality to improve aviation safety EGG HARBOR TOWNSHIP - Kenneth Allendoerfer donned a silly looking skullcap that had a bunch of electrodes and wires sticking out of it. While the cap might appear funny, the information collected from its sensors actually is part of some serious research involving one of the nation's most stressful jobs - air traffic controller. Allendoerfer and other researchers work in a Federal Aviation Administration laboratory that uses virtual reality to solve conflicts between humans and machines. Testing in the virtual world helps avoid many of the mistakes that accompany more traditional ways of designing and building new systems. In aviation, a mistake could come at a huge cost. "We model fresh ideas in a virtual reality. We do it before any significant money is spent," said Dennis Jefferson, a computer scientist who oversees the lab. The entire complex is called the Research Development and Human Factors Laboratory. It is located at the FAA's William J. Hughes Technical Center 10 miles west of Atlantic City. Step inside and you'll find a world of synthetic humans, 3-D imagery, simulated air traffic control towers, electrode-laden caps and other high-tech wizardry designed to make the nation's commercial aviation industry safer and more efficient. "We want to make sure the humans fit in with the technology," Allendoerfer, the manager of the FAA's human factors branch, said of the overall purpose of the lab. Virtual reality has become an important tool in the design, visualization and evaluation of complex aviation systems. Researchers stressed that airports, air traffic controllers, airlines and the flying public all have benefited from the lab, built in 1992 at a cost of $4 million. Greater demands are expected to be placed on aviation in coming years as the national airspace system becomes more complex. One of the lab's key research projects involves the so-called NextGen air traffic control system - the transition from the old, radar-based network to one that uses satellites to guide planes with more precision. Digital communication will be a key piece of NextGen. It will reduce the need for time-consuming radio transmissions between air traffic controllers and flight crews. Ben Willems, an FAA engineering research psychologist, believes that digital messages will eliminate some of the mistakes between controllers and flight crews during radio communications. "There are many places in that process when the human can make mistakes," he said of radio transmissions. Controllers would be able to concentrate on more of the "hard stuff" of their jobs - such as rerouting planes - if they are freed from some of the burdens of radio communications, Willems said. According to some predictions, controllers may have to handle three times as much airline traffic in the future as they do now. Willems explained that the lab exposes controllers to a much higher workload in a simulated environment to see how they cope. "We literally put them through the wringer," Willems said. The skullcap modeled by Allendoerfer, for instance, measures the electrical activity in the brain while controllers sit at simulated workstations, pretending to do their jobs. The lab also has devices to monitor a controller's heart rate and the amount of oxygen in the brain to determine the amount of stress they are under. In most workplace surveys, air traffic controller ranks as one of the nation's most stressful jobs. Peter Dumont, president of the Air Traffic Control Association, said the FAA's virtual reality lab has proved to be an immense help to controllers. The lab's testing "puts the human in the loop" from the very beginning in the quest to develop new technology, he noted. "Instead of trial and error in the field, they are developing it in the simulated environment," Dumont said. New workstations and other technology that could radically change the way controllers do their jobs are being developed at the lab. The virtual environment includes computer people that mimic real humans. These "synthetic humans" help to refine equipment and facilities before they are placed in the field. "It's easy to put something in a virtual environment before we put it into actual construction," Jefferson said. Design flaws can be eliminated during the computer simulations. The synthetic humans, nicknamed "Jack," are equipped with high-tech gadgets to make sure workstations, consoles, desks, chairs and other furniture will fit properly for real people. For instance, Jack can use a "dynamic finger ruler," a laser light that extends from his finger to measure the distance of an object he is reaching for. One of the most extraordinary parts of the lab is a room that features a virtual mock-up of airport air traffic control towers. One simulation replicates the panoramic views of the Boston skyline that controllers would have from the tower at Logan International Airport. Boston landmarks, such as Fenway Park and Hancock Place, are mixed with virtual images of planes taking off and landing at Logan's runways. A series of computer screens stretch across the wall to create airport simulations that look like a gigantic video game. Researchers can simulate emergencies and other scenarios to watch how air traffic controllers will respond. "From a safety point of view, you're unlikely to make mistakes," Allendoerfer said of the advantages of testing in the virtual world. Mistakes made by air traffic controllers in the real world could be catastrophic. Every day they are on duty, they can have thousands of lives in their hands. Dumont, of the Air Traffic Control Association, said the FAA lab is crucial for studying factors that affect controllers, including their workload and how they interact with technology. "It certainly is a job that carries a lot of responsibility and takes a lot of training. It is certainly considered a stressful job," he said. http://www.pressofatlanticcity.com/communities/eht/faa-lab-using-virtual-reality-to-improve-aviation- safety/article_3e030a56-ef5c-11e3-a2a0-001a4bcf887a.html Back to Top Safety fears over proposal to centralise air traffic control hubs in Melbourne, Brisbane (Australia) Pilots and air traffic controllers fear safety will be at risk if Airservices Australia pushes ahead with a proposal to merge some of its locations. The ABC has learned of plans to consider removing controllers monitoring airspace in Sydney, Adelaide, and Cairns, and hub them in Melbourne and Brisbane. Airservices Australia, which manages air traffic control in the country, is looking at consolidating some of its Terminal Control Units (TCUs). Once planes take off, they are monitored by TCUs while flying over busy metropolitan areas around 60 kilometres from the airport. Once they reach less congested airspace, they are then handed over to "en-route controllers", who are already based in Melbourne and Brisbane. Internal staff discussions obtained by the ABC reveal controllers are deeply concerned about the move. "The benefits of local knowledge, industry contact, career variety... cannot be underestimated," one controller wrote. "Disaster recovery and the other benefits of decentralisation are not to be scoffed at. "I think the idea of moving remote TCU's into major centres is flawed, and any 'paper' savings will be utterly negated by reduction of service provision, loss of employee satisfaction and reduced overall capability within the company," said another. Local knowledge important, say controllers One of the recurring themes among controllers is the importance of local knowledge - something former pilot Clark Gibbons knows all too well. Nearly 20 years ago he was flying a Cessna 210 near Canberra when its engine failed. He put his faith in air traffic controllers because he was surrounded by blinding cloud. He said he requested to land on Lake George, which he knew to be virtually empty. "They then gave us the [directions] - and when we have popped out of the cloud we've crashed into the side of a hill with no advice from them that we were not being put over Lake George," he said. "Ten seconds would have been the maximum amount of time... from seeing the trees, seeing the hill, having nowhere else to go but crash into the hill." Mr Gibbons and his other passengers suffered serious burns in the crash. The controller was based in Melbourne because Airservices Australia had consolidated the region's Terminal Control Unit. The Bureau of Air Safety Investigation (now Australian Transport Safety Bureau) found that the air traffic controller guiding the plane was not familiar with Canberra. "Although he received advice from another controller who was familiar with the Canberra area, the approach controller was not so familiar," the report said. "The limitations of the radar display, which depicted Lake George in general terms, prevented the controller from being certain of the aircraft's position with respect to terrain features." Airservices raised similar plans around a decade ago, but eventually rejected them because the business case was marginal. "It is appropriate that some of our ATC [Air Traffic Control] Operations groups remain decentralised especially when the financial case for centralisation is marginal and these moves result in dislocation for staff and their families," the 2006 letter to all staff from then-chief executive Greg Russell read. In a statement to the ABC, Airservices said no decision had been made, and the current suggestions were a review of all the available options. It said that centralising operations could improve career development and help remove duplicated infrastructure, equipment and maintenance. "Safety is Airservices' number one priority and a detailed safety analysis will be undertaken to consider any potential risks and effectively manage any future changes if they are actually made," it said. Labor's transport spokesman Anthony Albanese said he believed it was about "cost cutting". "We shouldn't be cutting costs when it comes to aviation safety," he said. The former transport minister's Western Sydney electorate is near Sydney's airport. "Common sense tells you that if you live and work at the actual airport, which is Australia's most significant airport - it's the most densely populated area in Australia - there's a reason why you want to have the air traffic control around that airport controlled from Sydney airport rather than from a remote location in Melbourne or Brisbane," he said. https://au.news.yahoo.com/a/24216010/safety-fears-over-proposal-to-centralise-air-traffic-control-hubs- in-melbourne-brisbane/ Back to Top Frontier Airlines plane hits jet bridge at Cleveland Hopkins Airport A Frontier Airlines plane hit a jet bridge at Cleveland Hopkins International Airport, officials say. (Lynn Ischay, Plain Dealer file photo) CLEVELAND, Ohio - Passengers had to exit the rear of a Frontier Airlines plane after it hit a jet bridge early Thursday morning at Cleveland Hopkins International Airport. There were no injuries but there was minor damage to the plane and damage to the jet bridge located on Concourse A, said Michele Dynia, a spokesperson for Hopkins. Few details were available early this morning. Dynia said it's unknown how many people were on the plane, an Airbus 319 which had arrived from Denver. The Airbus 319 has a capacity of 124 passengers. She also did not have information on exactly when the accident occurred, but said she was notified around 1:15 a.m. WKYC Channel 3 reports passengers sat on the plane for about an hour before they exited. Dynia said a walkway was brought to the plane and passengers exited from the back. http://www.cleveland.com/metro/index.ssf/2014/07/frontier_airlines_plane_hits_j.html Back to Top Airports Serving U.S. Tighten Checks on Stealth-Bomb Threat Airports including London Heathrow, Europe's busiest, stepped up security checks with unspecified measures in response to U.S. warnings amid concern that a new generation of bombs could evade existing scans. A number of overseas airports with direct flights to the U.S. have been asked to implement enhanced security checks in coming days, Homeland Security Secretary Jeh Johnson said in a statement last night. U.K. Deputy Prime Minister Nick Clegg said the threat could prove to be a long-term one. Scrutiny is being heightened as spiraling conflict in the Middle East prompts an increased flow of western jihadists. Newspapers including the London-based Times cited U.S. officials and security sources as saying the latest threat concerns an alliance of al-Qaeda-inspired terrorists in Syria and Yemen equipped with hard-to-detect "stealth" bombs. "We have taken the decision to step up some of our aviation security measures," the U.K. Department for Transport said in a statement today. "For obvious reasons we will not be commenting in detail on those changes." 'Substantial' Threat British Airways, the biggest carrier at London Heathrow (IAG) with about 1,000 weekly services to 24 U.S. destinations, said that while it's operating as normal the tighter checks mean travelers must arrive in good time for flights both at check-in booths and boarding gates. The airline works closely with airports and governments around to world on safety and security issues, it said in an e-mailed statement. Discount carrier Norwegian Air Shuttle AS (NAS), which started flying from London Gatwick airport to the U.S. this week, is aware of the security situation, Chief Executive Officer Bjoern Kjos said in an interview. The carrier commenced Gatwick-Los Angeles services yesterday and added New York flights today, with trips to Fort Lauderdale, Florida, following tomorrow. Passengers should not experience significant disruption from the extra checks, according to the DfT, which kept its assessment of the current threat level at "substantial." Steps could include measures aimed at finding non-metallic explosive devices able to evade detection by current equipment. Heathrow Airport Ltd. said it doesn't comment on security measures and that security levels are a matter for the DfT. Travelers will probably have to endure "another layer" of security for some time, Clegg said on London's LBC Radio, adding: "I don't think we should expect this to be a one off temporary thing." http://www.businessweek.com/news/2014-07-03/airports-serving-u-dot-s-dot-step-up-security-amid- stealth-bomb-concern Back to Top Back to Top Airbus: Pilots don't really need windows A flight deck with viewing screens could go at the base of the vertical tail, and possibly still have windows for seeing to the front and sides of the aircraft. Photo: Airbus/U.S. Patent And Trademark Office Future airliner flight decks may do away with windows and move out of the nose of the aircraft, according to Airbus. The European airplane maker filed a patent application Dec. 23, published June 26, for a flight deck that relies mostly or entirely on electronic viewscreens. The first advantage is aerodynamic, since flight deck windows require interrupting the ideal scalpel shape of the nose, Airbus wrote. Also, big windows and the reinforcement required for them add weight to the aircraft. Putting the flight deck at the front of the cabin takes valuable space away from the cabin, "thereby limiting the financial profits for the airline company exploiting the aircraft," Airbus wrote. Without the need for windows, the flight deck could move "to an unused zone of the aircraft, and in particular into a zone difficult to configure for receiving passengers or freight," Airbus wrote. One possibility is the base of the tail, where the flight deck could still have some windows. Another is in part of the cargo hold. Finally, relying more on viewscreens would improve pilots' perception and awareness, by giving a more complete view of what's going on outside the aircraft, according to Airbus. In addition to the viewscreens, Airbus envisions a system that could project holograms of objects such as storm clouds and ground obstacles, and chart a course around them. "The object of this preferred version is to immerse the pilot in a three-dimensional universe, at the center of the action," Airbus wrote. http://www.seattlepi.com/business/boeing/article/Airbus-Pilots-don-t-really-need-windows-5596374.php Back to Top Auburn University upgrades aviation program with focus on research and industry Kris Frost, right, a sophomore in professional flight management at Auburn University conducts a training flight over campus. A five-star linebacker, Frost says aviation was a big part of his decision to come to Auburn. (Auburn University) AUBURN, Alabama -- Just a year after Auburn University considered eliminating its professional flight program, university officials are moving to expand the school's aviation program. University official announced Tuesday plans to upgrade and expand its aviation program to focus on research and the support of the state's aerospace and aviation industries. At the heart of the expansion is the creation of a new aviation center to be located at the Auburn University Regional Airport. University officials predicted the center will strengthen academic and research programs as well as recruit industry to Alabama. "We're building a more robust, visionary aviation program that creates opportunities for students and fosters economic development in the state, said Bill Hutto, who will direct the new center. Hutto is also director of the airport and a member of the school's aviation faculty. The center will oversee Auburn's flight school. University officials said students will see more opportunities to follow industry trends, changes and priorities and interact with potential employers. The announcement comes after the Federal Aviation Administration announced a ruling in September that will allow graduates of Auburn's flight school to become commercial pilots with fewer flight hours than normal. It also comes after the Aviation Accreditation Board International reaffirmed the accreditation of Auburn's aviation program in March. http://www.al.com/news/birmingham/index.ssf/2014/07/auburn_university_upgrades_avi.html Back to Top THE ALPA 60TH AIR SAFETY FORUM A Celebration of Pilots Helping Get the Job Done Safely & Securely August 4-7, 2014 | Washington Hilton | Washington, DC SPONSORSHIP & EXHIBITING OPPORTUNITIES AVAILABLE Contact Tina Long at tina.long@alpa.org for more information or click here to download the sponsorship brochure.
