You don't have to be too worried about it, since the aircraft is able to cope with this. People are instructed to turn them off in order to avoid some disturbances and parasite noise in the communication between the pilot and the airport. As electronic devices using radio frequencies, they could also in theory cause some troubles to some aircraft equipment's ...

As a cabin crew member for long time, I can tell you that your responsibility ends by notifying a crew member, that's it. Let the crew members deal with it. This is true for all other violations, unless it's a life threatening situation that cannot wait, for example fire! Grab the extinguisher and fight the fire. But that's a whole different issue. ...

I am a software engineer and I also test the software on many different smartphones and tablets. I fly frequently within Europe, so my answer will be limited to this area. However, this is also from west to east and east to west, outside of the Schengen region! As a Dutch citizen, I rarely need a visa to travel, which makes this easy. I do carry a lot of ...

A few years ago I read a study about cell phone usage on U.S. domestic flights. Using RF locating equipment, they determined that the average U.S. flight has 2-3 cellphones left transmitting during the flight. Unconfirmed pilot anecdotes notwithstanding, if there were any significant risk of planes malfunctioning from cellphones, they would be falling out ...

Your personal safety is not affected by your fellow passenger using a cellphone. In the US, the FCC (not the FAA!) has limited use of cellphones on aircraft because of the potential effect on cell towers on the ground. From an empirical standpoint, if there was a significant risk, it would have been observed many times by now as people frequently leave ...

There are three concerns: 1) terrorism; 2) export/import limitations; and 3) the fire hazard from the lithium contained in the cell phone and laptop batteries. Terrorism: the difficulty of addressing terrorism is that the level of screening and scrutiny is often arbitrary depending on the current political climate and the capriciousness of the security ...

I didn't know until I started working in the field, but the most serious problem with leaving your cellphone on is the frequent failed attempts to connect to the many cell towers you are passing over at 500 mph. Not only does this tie up the towers' ability to connect with other people, it drains your handset battery faster.

My father's an airline pilot (United Airlines) and this is something that I've asked him about at length. The idea that any kind of signal from your cellphone can interfere with a plane's electronics is purely myth (Though one that the airlines are happy to allow to propagate). There're endless such signals in the air at all times anyways, and modern ...

Note that while EMI concerns are practically bogus considering modern airplanes and mobile phones, you are still required to turn off all electronics during takeoff and landing, for your own safety. In case your airplane has to make an RTO maneuver or catches fire, you won't see it coming if you're concentrated on your phone or laptop. You may get hurt ...

I am going to give you a different take on this question. It is in your question (customs) and seems to be overlooked in most answers. It is not really about planes, batteries, safety, or how big your bag is, it is mostly about the law of the departure and destination countries (not usually transit countries). Many countries prohibit what you can bring in ...

eBags provides a reasonably thorough chart of US domestic airlines and their carry-on size limits. Without knowing which airline you're using, there's no way to provide an absolute answer, but you can get a general feel this way. Also note that just because you're permitted a bag in your carry-on allowance does not alone guarantee that you'll be permitted ...

The consensus on the internet is mixed, with people who managed to carry their soldering iron in hand luggage without any problems, as well as others who had it confiscated and thrown away by TSA. However, the TSA prohibited items search engine does not provide any indication on the topic. The only US-related official source I could find is the Delta ...

Your Safety is Compromised if You’re an Intervener If you feel compelled to do something about someone 'breaking the rules' you may want to consider why it's so important for others to follow them. Primarily, if you find yourself wanting to intervene and play Sherriff you may find yourself in a compromising position if the person you are trying to ...

As pointed out in the answers given so far, a few mobile phones are not going to cause problems. We then have a few 100 milliwatt transmitting power on frequencies that are totally different from what the plane uses to communicate with ATC, and all equipment used by the plane are well shielded from EMF interference, so it looks like we can just allow ...

It would help to know which airline you will be taking as the allowed bag size is airline dependant. Anyway, I have found a page where you can spot the allowed bag size and weight for a lot of airline companies : http://wikitravel.org/en/Airline_baggage
