Boeing says the iPad is the worst offender for signals that could cause interference with aircraft equipment, according to ABCNews. Blackberrys and iPhones are also said to be well over the accepted limit.
A recent report by The International Air Transport Association (IATA) looked at 75 incidents of "electronic interference" in flight system that pilots and crew believed to be caused by portable electronic devices.
Twenty-six of the incidents in the report affected the flight controls, including the autopilot, autothrust and landing gear. Seventeen affected navigation systems, while 15 affected communication systems. Thirteen of the incidents produced electronic warnings, including "engine indications." The type of personal device most often suspected in the incidents were cell phones, linked to four out of ten.
Dave Carson of Boeing says that personal electronic devices radiate signals that can disrupt highly sensitive electronic sensors hidden in the plane's passenger area. ABC's own aviation expert John Nance disagrees with the findings.
"There is a lot of anecdotal evidence out there, but it's not evidence at all," said Nance, a former Air Force and commercial pilot. "It's pilots, like myself, who thought they saw something but they couldn't pin it to anything in particular. And those stories are not rampant enough, considering 32,000 flights a day over the U.S., to be convincing. If an airplane is properly hardened, in terms of the sheathing of the electronics, there's no way interference can occur."
One would think that if the Federal Aviation Administration approved the iPad as an alternative to paper charts, it would be safe for airplane use.
The prohibited use of cell phones on airlines is not a FAA/Airline restriction, it's actually a FCC law. As cell phones that continuesly "search" for a signal, tend to tie up multiple cell towers. Since it would both be uneconomical and extremely time consuming to test each and every electronic device against every possible electronic system of an aircraft, it's quicker/cheaper to just have everyone turn thier personal equipment off until passing 10,000 ft.
Once they bring the iPad into the cockpit wouldn't they then turn on Airplane mode on the device anyways, thus turning off any possible radio interference? You'd think airplane mode would be required to be on when they are going to fly.
I guess the mythbusters will have to test this again and this time with an ipad.... but same result... you can not bring down a plane with a phone or any other personal device that is not made to crash a plane.... but if the pilot has the ipad that could be trouble
Nance made the definitive point. Whenever there is electrical/electronic interference, the fault almost always rests with the device being interfered with. The proximate cause is a lack of adequate shielding.
