Kännykkä lentokoneessa

Käydäänpäs ekana Googlessa ja joku uutislinkki sieltä, vuosi 2011. Riski on mahdollinen. Miksi ottaa se? Satojen henki vaarassa siksi että pitäisi kännykän päällä.

"But a confidential industry study obtained by ABC News indicates there really could be serious safety issues related to cellphones and other PEDs."

"The type of personal device most often suspected in the incidents were cell phones, linked to four out of ten."

"In other events described in the report, a clock spun backwards and a GPS in cabin read incorrectly while two laptops were being used nearby. During another flight, the altitude control readings changed rapidly until a crew member asked passengers to turn off their electronic devices. The readings returned to normal. "

Boeingin Carson: "Asked if a cellphone's signal could really be that powerful, Carson said, "It is when it goes in the right place at the right time.""

"To prove his point, Carson took ABC News inside Boeing's electronic test chamber in Seattle, where engineers demonstrated the hidden signals from several electronic devices that were well over what Boeing considers the acceptable limit for aircraft equipment. A Blackberry and an iPhone were both over the limit, but the worst offender was an iPad. There are still doubters, including ABC News's own aviation expert, John Nance."

"But Boeing engineers told us that signals from PEDs could disrupt the navigation and communication frequencies on older planes, which are not as well shielded as the newer models. And anything that distracts the pilots in the cockpit is considered a true threat to safety."
