Is electronic device harmful to the flight landing? @ 這是一個快樂學習用心生活的小天地

omkevin 說︰

I was asked by an American Airlines flight attendant to turn off my digital camera on the approach to LaGuardia. She said, "That's an electronic device, I have to ask you to turn it off."
I have never been able to find anything definitive on whether digital cameras can interference with flight systems. What have the members of this group read or heard about it?
Thanks,
Kevin

The Mythbusters (a show on the Discovery channel, if you aren't familiar with it) tested the "myth" of whether cell phones could actually interfere with the avionics of a modern aircraft. They determined that there really seemed to be no discernible effect at all, but still agreed that if there was any chance of interference, no matter how remote, the airlines are right to ban cell phone usage just to be on the safe side. But that's cell phones--I've got to think the electromagnetic interference generated by most other devices (cameras, cd/dvd players, etc.) is minuscule in comparison. So to me, banning *all* portable electronics does seem silly. But again, given the modern notion of combining electronic devices, I guess it's just easier for the airlines to say "no electronic devices" than to pick and choose, you know?

Yes, I've thought the same thing -- that the airlines and flight attendants often operate on the principle of "all electronic devices." It would be interesting and useful to have a study made, in which something specific was said about cameras. I can find studies on the net about EMI (electromagnetic interference), but the ones I've found so far do not even mention cameras.

One common-sense point: probably a lot of people forget or do not turn their phones off on every single flight out there. Probably 95% of passengers on a given flight have a cell phone in their pocket. I have yet to hear of a plane crashing or experiencing difficulty due to phones interfering with avionics. If phones (and other devices including cameras) were really dangerous, they would and should take them away from you at security like they do other dangerous things.
My guess: the airlines are worrying about the minute, distant and mainly theoretical possibility of interference.

Totally. If personal electronic devices really posed a risk, do you think they'd leave it us to switch them off?
Furthermore, you never used to get told off for listening to mp3 players during take-off / landing. We'll be asked to not talk next, in case we put the pilot off.

Well, better safe than sorry. It's not exactly a hardship having to manage without a digital camera or mp3 player during take off or landing or a mobile phone for the duration of the flight, is it?!
The solution - use a film camera on-board instead.

Some airlines don't want cameras used onboard for legal reasons.
Photographic evidence of some kind of mishap or fault spotted within the aircraft for example, could be used against them.

There are two issues that you all are mashing together:
1. Is a digital camera an electronic device? The answer is yes, no doubt about it.
2. Does the use of electronic devices interfere with the plane's own electronics? I agree that this is debaeable but it doesn't matter, if they have rules about iPods and computers, cameras fall under the same rules.
The solution to this is to be a bit sneaky and don't advertise that you're using a camera as the flight attendants make their last walk through safety checks and try not to sit near the bulkhead where they sit and can see you.
I routinely take pictures on landing after they've walked by, here's one on approach to JFK.

I fly about ten business trips a year in the western US. I take a lot of pictures on take-off, landing, and throughout the flight. I don't attempt to be discrete, but I'm not overt, just shooting out the window. I have never been challenged by a flight attendant. I've never given it half a thought.

I did try to make more pictures after the attendants sat down. But it turns out that passengers can get involved, too.
A man was sitting two seats from me, next to my wife. We hadn't spoken on the flight except to say hello. He saw me snapping one more photo. Then he caught my attention and said, "Chief, have you heard of the show EMI? Do you know what EMI is? That's electromagnetic frequency. In the New York area there have been three plane crashes due to EMI. Now, she asked you to turn that off."
At that point I simply turned away from him and turned off the camera. There was nothing else to be done. What I was hearing from him did not make sense, but you're not going to start an argument about safety right on the plane, with other passengers and attendants listening. These are not the days to cause a scene on airplanes, and that is not my temperament anyway.
But I do think that what this gentleman had a problem with was my not heeding a person in authority. On the takeoff hours earlier, he had seen me take many photos and said nothing.
I do want to do what any pilot or attendant asks me to do onboard, but this is one request that has never made sense to me. No one has ever mentioned cameras on the intercom when listing prohibited devices; the inflight magazine does not mention them either.
I will never knowingly use a cell phone or laptop on approach or takeoff. All I have read and heard indicates that these devices, and some others, are genuinely potential risks. But a camera? That's what I'd like to get some specific information about.

ive only been told once not to take pictures on a flight, ive taken pictures on many others in plain view of flight attendants before...this flight attendant was a little difficult from the start though and it was an RJ so she was alone. i think most flight attendants are fine with cameras, but you may run into one every now and then that when they say electronic devices, they mean ALL devices.
