Is using electronics on planes dangerous?
Perhaps, but not quite in the way you thought:

And, of course, there was the whole contradiction between not allowing passengers to use iPads, but pilots were using it in place of printed manuals. Quote:

There have been numerous threads on this topic. Do a search.
Short answer is yes, they can be if the plane's electronics were not specifically designed to handle it (cable shielding, etc.) Ever put a blackberry next to a speaker phone and listen (radiated suspectiblity). Now imagine a pilot trying to listen to the tower doing critical final manuevering to landing during an IFR approach. If everyone put their ipad on airplane mode, they can use them today midflight. If they all have 3g ipads and have the 3g phone service on, that could be a problem. |

Well we know iPads are safe, because the pilots use them!

No, we don't. We don't know if they are modified or run in a certain mode and we don't know if they are used on all planes or just some.
For instance, I remove radios from laptops when used in certain areas. Under some circumstances, in some areas, we allow laptops with the radios switched off. We assume a lot but don't know much. |

When I was in the USAF back in the 80's, I worked on KC-10 avionics systems, which is just a military version of the commercial DC-10. When cell phones started becoming really popular we took one up in the cockpit and turned on all the navigation systems and had a phone conversation. Sure enough, quite a few of the gauges started acting strangely. Of course, we were in the cockpit so I don't know what kind of range there would be for such an affect, we did walk into the back and the strangeness stopped.

This subject has already been discussed to death. I very much doubt that anyone's got anything useful to add to it that hasn't already been said a thousand times before.

I know that this is blasphemy on mobilereads... but I fly with paper books just so that I don't have to go for huge periods where I can't read (on my kindle).

I'm not claiming that the dangers are real. Modern devices are very low power and very high frequency, so it should be possible to design instruments for aviation that filter that noise out. On the other hand, there are so many electronic devices out there that it is (as you suggested) impossible to test everything independently. |

They don't 'ban' them. They tell you to turn them off until the captain deems it safe, then they don't bother to check if you do or not.

The question you have to ask yourself is why? There are probably dozens of reasons why they are sticking to the older systems and a handful of reasons to modernize. It is a lot easier to build new infrastructure (e.g. in the 1950s when air transportation was expanding) than it is to replace operating infrastructure.

We just flew to Arizona from Michigan and back, and on both flights they were very clear that, until we hit 10,000 feet, no electronic devices could be used, not on airplane mode, not iPods to listen to, not nothing not nohow. they were quite clear and quite emphatic about it. These were older planes, though.

While I generally believe it is a bunch of hogwash, I nevertheless always comply with the instructions to turn every thing off. I will, however, turn on my Kindle as soon as possible.
