Since when can one use a mobile phone inside a plane?

Answer 1

It is not allowed on commercial carriers, I do not know the real reason.

I use mine frequently on board. I happen to fly a lot over north america on a Dassault Falcon 900 Jet, although there are some areas when signal is not available, most of the time it is, and it works great.

Answer 2

As far as I know, between the FCC and the FAA, you are not allowed to.

There have been companies that have been developing cell sites to work inside of planes. I believe there are working prototypes of these types of cells, but I am not sure if they are in use on passenger planes at all.

Cell phones on planes have been banned for two reasons. The first, is the fear of RF devices interfearing with equipment on the plane.

The second is the fear of overloading a cell system due to the near constant handoffs between cells. A cell site has a radius of about 3 miles in an urban environment, so about 6 miles across. The "circle" the site transmits in is divided into three rougly equal sections, alpha, beta, and gamma. Alpha, Beta, and Gamma sectors are treated as individual "cell sites" by the call processing equipment.

Assuming each cell sector covers roughly two miles...

A plane traveling at 500 MPH covers a mile in about 7 seconds. This suggests that the plane would move completely into and out of a cell sector in about 14 seconds. In a CDMA system (the most common in the US), a mobile phone attempts to talk to 3 cell sectors at any given time.

So the fact that a plane enters and leaves a cell sector in about 15 seconds and a phone is trying to talk to 3 sectors at a time, the phone is probably actually changing a sector roughly every 5 seconds.

One call by itself doing this wouldn't be a big deal. If many people do this, it definately might cause issues with call processing equipment.

Answer 3

Niether the FAA nor the FCC prohibit the use of cell phones on aircraft. It's left up to the individual aircraft operators to make that call.

Fact is, we use them on our corporate jets frequently -- the pilots could care less and swear that it has never affected navigation or safety.

That said, once you get above about 5,000 feet above ground level, the signal is lost. I've tested this many times and state this from personal experience.

Answer 4

Flight mode does propose that you'll shop your telephone switched on and in use on a plane, yet i do not imagine it truly is properly well worth the issue. I propose, you may want to get into various hassle if that's a strict airline, or you've it confiscated. basically change it off thoroughly and placed it on your bag, I propose, it truly is surely some hours, i'm particular you may stay with out it. you isn't in a position to textual content or call every person besides with it in flight mode.

Answer 5

It is forbidden by carriers operating in and out of the UK.

However, unlike the old analogue systems, it is rare to have a digital phone signal much above 1500 feet.

Answer 6

Here in Australia... qantas are going to have a trial period where people on the plane can use their mobile phones. They are going to monitor the plane in flight to see if there are any disruptions to the flight. (I for one am not going to be a volunteer for this trial run) Would you??

Answer 7

the announcement that all electronic devices must be turned off is BS. they do not effect the aircraft. this is made so that you pay attention to the in flight instruction and that y the cell phones do not work until you are about @ 1000 feet. they are above the towers in flight, in addition they do not effect the navigation of a flight.

Answer 8

Not sure when but you can use a cell while the plane is boarding, and you may use one after landing as it taxi's to the gate....

Answer 9

About 2 months ago they starting allowing it during the taxiing to the gate.

Answer 10

When you know your plane had been hijacked by some extremists and heading to crash into a building somewhere.
