Pilots say it is critical to turn off devices
Smartphones on planes: Pilots say it is critical to turn off devicesThe regional airliner was climbing past 9,000 feet when its compasses went haywire, leading pilots several miles off course until a flight attendant persuaded a passenger in row 9 to switch off an Apple Inc. iPhone.
“The timing of the cellphone being turned off coincided with the moment where our heading problem was solved,” the unidentified co pilot told NASA’s Aviation Safety Reporting System about the 2011 incident. The plane landed safely. Senator Claire McCaskill to actor Alec Baldwin have bristled at w rolex watches for sale hat they say are excessive rules restricting use of tablets, smartphones, laptops and other devices during flights.
More than a decade of pilot reports and scientific studies tell a different story. Government and airline reporting systems have logged dozens of cases in which passenger electronics were suspected of interfering with navigation, radios and other aviation equipment.
The FAA in January appointed an advisory committee from the airline and technology industries to recommend whether or how to broaden electronics use in planes. The agency will consider the committee’s recommendations, which are expected in July, it said in a statement.
Laboratory tests have shown some devices broadcast radio waves powerful enough to interfere with airline equipment, according to NASA, aircraft manufacturer Boeing Co. Federal Aviation Administration its pilots and mechanics reported 27 suspected incidents of passenger electronics causing aircraft malfunctions from 2010 to 2012. Atlanta based Delta said it couldn’t verify there was interference in any of those cases.
The airline industry has been divided. Delta said in its filing that it welcomes more electronics use because that’s what its passengers wanted. United Continental Holdings Inc. said it preferred no changes because they’d be difficult for flight attendants to enforce. FAA last year to allow wider use of devices. Personal electronics don’t cause interference, CTIA said in a blog post last year.
Passengers’ use of technology and wireless services “is growing by leaps and bounds” and should be expanded as long as it is safe, the Consumer Electronics rolex watches for sale Association, an Arlington, Virginia based trade group, said in its filing to the FAA last year.
Federal Communications Commission Chairman Julius Genachowski agreed in a Dec. 6 letter to the FAA.
Broader use of on board electronics would help providers of approved aircraft Wi Fi services by letting passengers use them longer. Gogo Inc., based in Itasca, Illinois, says it has 82% of that market in North America, and Qualcomm Inc. on May 9 won permission from the FCC to proceed with a planned air to ground broadband service for Wi Fi equipped planes.
The FAA prohibits use of electronics while a plane is below 10,000 feet, with the exception of portable recording devices, hearing aids, heart pacemakers and electric shavers.
Once a flight gets above that altitude, devices can be used in “airplane mode,” which blocks their ability to broadcast radio signals, according to the FAA. There’s an exception for devices that aircraft manufacturers or an airline demonstrates are safe, such as laptops that connect to approved Wi Fi networks. aviation system transitions to satellite based navigation, according to the FAA. In order to improve efficiency, planes will fly closer together using GPS technology.
Following techniques suggested by RTCA Inc., a Washington based non profit that advises the FAA on technology, airlines rolex watches for sale have been able to install Wi Fi networks allowing passengers to browse the Web in flight.
Four in 10 airline passengers surveyed in December by groups including the CEA said they want to be able to use electronic devices in all phases of flight. Thirty percent of passengers in that same study said they’d accidentally left on a device during a flight.
McCaskill, a Missouri Democrat, has called for lifting restrictions on non phone devices such as the Kindle if passengers keep them in airplane mode, Drew Pusateri, her spokesman, said in an interview.
There has never been an incident of a plane having problems because of someone having a device on in the cabin
The existing rules are “ridiculous,” she said in an interview.
“I was aware from the research that’s been done that there has never been an incident of a plane having problems because of someone having a device on in the cabin,” she said.
The dangers from radio waves interfering with electronic equipment has been known for decades. A fire aboard the aircraft carrier USS Forrestal in 1967 killed 134 people, when a rocket on a fighter jet accidentally fired after a radar beam triggered an electronic malfunction, according to a 1995 NASA review. commercial aircraft began in 1966 after research found some portable radios interfered with navigation equipment, according to the FAA’s request last year for comments on whether it should change existing rules.
In one 2004 test, a now discontinued Samsung Electronics Co. wireless phone model’s signal was powerful enough to blot out global positioning satellites, according to NASA. The device, which met all government standards, was tested because a corporate flight department had discovered the phone rendered a plane’s three GPS receivers useless, NASA’s researchers reported.
While incidents haven’t led to any commercial accidents and and are difficult to recreate afterward, they continue to pile up. A log kept by the Montreal based International Air Transport Association airline trade group recorded 75 cases of suspected interference from 2003 to 2009, Perry Flint, a spokesman for the group, said in an interview.
Peter Bernard Ladkin, a professor of computer networks at the University of Bielefeld in Germany, compiled similar accounts from pilots in Europe, he rolex watches for sale said in an interview.
“These are serious, conscientious pilots,” Ladkin said. “They know what they’re doing. They don’t subscribe to theories about ghosts or something.”
Damaged devices have transmitted on frequencies they weren’t designed for, according to David Carson, an associate technical fellow at Boeing who has participated in industry evaluations of electronics.
