MaxLV: After all they do contain a Lithium battery, and we all know how dangerous they are, dont we. (Just ask Boeing)

If you ship a lithium battery anywhere it requires special packaging, special delivery instructions, etc... and yet you can carry them on to an aircraft in a cell phone.

Safer in a pressurized cabin than in depressurized cargo, no?

If electronic consumer devices (not just cell phones) are risky on aircraft, why are you allowed to use those devices once you're in the air?

If RF interference could cause momentary failure of flight systems a failure during take off/landing would be a major problem. A failure in air not so much, there's already plenty of lift and plenty of space to manoeuvre/recover.

There is also the fact that during the safety briefing they want you to shut the eff up and pay attention, not be yacking on a cellphone or engrossed in candy crush

And just a side note: don't even think about importing these for your own use. You will get a mighty big fine, and hit with a big stick over the knuckles from PeterReader!

Cabin crew can see who is watching and who isn't, kick anyone not paying attention off the plane.

Why import when you can build one?

I usually travel with at least two or three mobile transmitting devices. The number of times I've accidentally left at least one of them on and transmitting....

Modern planes have pretty good shielding. Not just because cell phones came about because interference can come from a variety of places. Mythbusters did a show on it once, and the only way they could get any kind of interference to register was basically in a an cockpit they had built from old instruments, with no shielding etc.

The fact that airlines get upset when I want to read my kindle on landing really annoys me. I'm pretty sure that the purser dimming the cabin lights for landing is more likely to have an effect on the plane systems than my changing the page on my eReader.

I'm convinced devices to block cell phone signals are a myth - otherwise they would be used in all movie theatres!

What an interesting thread this turned into! If you want to have a laugh and also think about how nonsensical the whole thing is here are some memories of my time working on the other side at the airport

CheckIn
"good morning sir have you got any aerosol cans or anything of an inflammable nature in the bags " Pax (Passenger) "No"
Me oh good I trust this person to answer honestly!

"Excuse me sir what is in the box ?(you are checking in)" "Oh Fireworks" "oh a camping stove" "oh 10 cases of ammunition" These responses happened to me in some form about 20 times a year.

Pax "I just realised the bag i checked in 20mins ago had my phone in it and i left it on" Maybe once or twice a day

Spoiler alert for Flying in New Zealand

Baggage is not checked by x ray in regional airports or carry on luggage or persons checked as it is to expensive!

So i don't think we have to worry about the occasional phone left on!.

There is a good deal of irrational fear of cellphones - the UK hospital 'total ban' policy being a good example. Coincidentally, a lot of hospitals had very lucrative deals with external providers to provide bedside phones to patients - at huge cost to those who called them
Another good example is the policy of banning their use at petrol station forecourts. Do the maths - how many times in the last twenty years have cellphones been used next to petrol pumps? Probably millions, if not tens of millions. How many documented instances of fires being caused? None at all. So, what are the odds of a fire being triggered now?

Klipspringer: Cellphones left on while traveling on a plane probably cause more chaos on the mobile network than to the plane itself.
Imagine how many times a phone will be switching bases stations at low altitude and when travelling at speed. Who knows if they will actually work at 30 000feet? The signal from a base station can surely reach that height? Probably not? Maybe JohnR can comment?

Anyhow. I read somewhere that Air NZ pilots are now using ipads

Yes, cell phones (or at least cellular modems) do work at high altitude. A New Zealand product is the Flightcell DZM which uses cellular (and satellite) phone netwroks for tracking recreational and commercial planes.
Air New Zealand have at least trialled them (in conjunction with their iPads), and may now be using them regularly.
I'll find out if/when the DZM typically switches from preferred cellular to satellite on commercial flights in New Zealand. A light aircraft flight from Christchurch to Nelson had continuous cellular coverage the whole way.

Just the other day when filling up I noticed that cellphones needed to be switched off when putting in petrol.

This was at a Z station.

What REALLY annoys me on a plane is that the catchall ban on "or other electronic devices" has resulted in my being asked to switch off my camera when taking photos on several occasions, during descent.

My protestations that it has no transmitting function just falls on deaf ears and the one time I tried to be smart and ask the flight attendant when was the last time she heard of a camera being used to take over an aircraft, just resulted in much rolling of the eyes and and a "just switch it off please sir".

No Myth a Church was fined in New Zealand for turning one on every Sunday morning and taking out a local cell site even stopping 111 calls
