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 ...

In the US, as of 16 September, from the Federal Aviation Administration: Following a Consumer Product Safety Commission recall of the Samsung Galaxy Note 7, the FAA is issuing general guidance to airlines about the rules for carrying recalled or defective lithium devices on board aircraft as cargo or in carry-on luggage. And Samsung's recall of the ...

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 suspect you may be barking up the wrong tree here. In short, satellite Internet is likely vastly more expensive and limited than you expect, while regular old cellular networks are likely far more accessible that you'd expect in the developing world. This may change in a few years when high-speed satellite networks like Starlink start rolling out, but as ...

Do not worry, Wifi pass phrases for personal use should only be in printable ASCII characters, in other words English characters. They do not support Unicode or other codepages. For more details check the Wikipedia's Wi-Fi Protected Access page. Except if you are redirected to a webpage for authentication, that's a whole different story and Karlson's ...

This model is prone to spontaneous battery combustion, not desirable inflight. A specific example of this is shown here: Plane crew douse smoking Samsung phone

The FAA regulation has this to say: If requested by passengers, their photographic equipment and film packages shall be inspected without exposure to an X-ray system. I am unaware of any official TSA word on this but it'd be very hard to imagine them contradicting the FAA. Anything is a "photographic equipment" if you try hard enough. First ask ...

Those circled holes will be for various plug style's grounds, however -- That is not a standard socket. That is entirely an invention of the Chinese junk sellers. It has not been approved by any competent testing laboratory, and it definitely never will. This type of socket is simply trying to adapt too many kinds of plugs, at the expense of safety, and ...

A breaker tripping is a serious sign of trouble. Something shorted or started to draw excessive current. If not for the breaker, it would probably have caught fire. (Or the circuit was already overloaded - but since it happened in two different places, that seems unlikely.) So this is a safety hazard if not resolved. Since it doesn't happen normally, I ...

No. I have designed headphones for airplane use and there is no difference from designing connectivity for regular consumer electronics use. Physical connectors vary from airline to airline and from aircraft to aircraft and some will require an adapter, at least to get a full stereo experience. There is some "normal" mechanical risk: airplane seats ...

All the middle holes are there for accepting various types of ground (earth) pins. Specifically, the top two holes are there for British plugs (BS 546, BS 1363), while the bottom two are there for Brazilian, Danish and Swiss plugs. As always, Wikipedia has the gory details: https://en.wikipedia.org/wiki/AC_power_plugs_and_sockets

It's a port called an eXport. It was part of the Panasonic IFE system OK I think I found it! About 10 years ago Panasonic's IFE system (which appears to have been used on the B773ER and A333) contained a new port called eXport. It was a 9-pin mini-DIN port for iPods. You could purchase an adapter cable made by Griffin that was essentially an adapter ...

There are a variety of strategies you can use but they all involve a cost of time. I use different strategies in different places. First and foremost is what we calling "walking the campsite" (because it came from camping trips where leaving something behind could be catastrophic). You literally walk from room to room in the hotel (or wherever you are) ...

There's no mention of electronic boards etc in the TSA prohibited items list. So provided they aren't so heavy as to be a potential "blunt instrument" weapon, you should be ok. If they're in original packaging, that might help. Of course, they don't have to let any items through, restricted list or not. You may also wish to check the website of your airline,...

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 ...

Seems unlikely it's anything more than normal electrostatic discharge. The fact that it only affects you could be related to your clothes or shoes (especially if they are made of synthetic fibers). I also wonder whether the moving conveyor belt could be acting as a Van de Graff generator. Do you not get shocks like that under other circumstances? (I live ...

External drives (or internal ones - same drive, different case) will have zero problems with commercial air travel. X-rays don't affect them, and any in-flight vibrations capable of damaging a disk drive will also destroy the airplane. Now that's assuming it's turned off. Running drives don't like to be knocked around, but that applies on your desk too. As ...

For Android depending on the model of your phone you may have to add Russian Language to the available keyboards. I have Galaxy S5 and under Settings -> Languages and Input you should be able to do this from the Galaxy App Store. You should be able to do the same for the iPad just add a Russian Language, which will allow you to switch to it and make the ...

Am I correct that adapter mode would burn a US appliance, or am I wrong? Yes, you are correct. If used in "adapter" mode, the voltage is not adjusted or converted in any way, and in most cases a device expecting only 120V (USA/North America/etc.) will be damaged when plugged into the 240V source. But it's worse than that. Even when used in "converter" mode,...

Looks like a standard “kettle lead” or IEC 60320 C13/C14 lead to me, pretty easy to get anywhere there are computers - they usually breed in drawers or the back of cupboards when noone is looking. Should be able to get one at any computer parts store - just ask if you dont see them on display, as people so infrequently buy them on their own (because they ...

Unfortunately the removable prongs are specific to this adapter. They're not the same as the removable prongs on a different adapter. So good luck finding the right ones. Perhaps there were a bunch of different prongs in the box when you bought it, and you threw the other ones away. Perhaps they put the right one on at the factory. However, it is labeled 100-...

You're overlooking the fact that mobile telephony is a far more efficient way of connecting people in remote areas than is wiring up everyone's home. Governments and telecommunications companies, at least, have not overlooked this, so cellular connectivity is generally good in towns everywhere. You should certainly expect to find good cellular service and ...

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 ...

For hotel rooms there is an easy solution: It is called the "hotel safe". Earnestly, do not store important valuables in hotel rooms. Even cheap hotels have very likely a cupboard which is under constant supervision at least at daytime. If you have a rented apartment you have another situation. Burglars and thieves have the following mindset: Break in as ...

Technical Aspects The key part of the quote about pilots leaving the sat phone on the dash is the 'dash' part. The dash is under a glass surface, which is almost completely transparent to RF signals and has a nice, wide view of the sky, where the satellites are. This will not translate well to the cabin, where the fuselage is not made of glass and is ...

I frequently fly all over Europe with shoe-box PC's or various measuring devices in carry on luggage. The measuring equipment is very expensive: € 250.000 is pretty normal for a single device. You don't want to let it out of your sight or risk a baggage-handler to throw a suitcase around. And they don't like temperature fluctuations much (calibration issues)....

India has a 220/240V 50Hz electrical supply, while the United States delivers 110/120V 60Hz electricity. However, most electronic devices like laptops and tablets have dual-voltage power supplies, which accept both. You'll want to make sure this is true for the devices you're buying by checking the label to ensure it also accepts 240V 50Hz power. This will ...

Since most (all?) computer museums can qualify as retrocomputing museums, you might find this list of computer museums useful: https://en.wikipedia.org/wiki/List_of_computer_museums You could also look at science museums and see whether they have some computer section. E.g. the large Polytechnic Museum in Moscow, Russia has a nice computer section: The ...
