Well said IforB.

I always follow the safety rules .. mainly because they are there for a reason, after all, if a plane stops moving it becomes a large stone. it isnt as if you can just get off. !

I accept what you say, and also acknowledge the fact that you have servo assistance on hydraulic systems as well as sensors etc.

I was just winding up the not to joyful stewardess who sat and moaned for the duration of the flight, taking advantage of her "blondness" for want of a better word.

I do have a few questions though ... I wonder if anyone can answer them ?

Why can you not have a portable radio switched on as it is just a listening device and does not broardcast ? Same for a GPS reciever ?

Secondly, why do they always make you open the window shades during landing and take off ?

In case it all goes horribly wrong and you have to evacuate, it helps to see if there's any pesky fires in the way.

Ignore anyone who says they use the blind status to indicate whether the plane's been taken hostage hehe

I believe at night it's to adjust your eyes to the dark in case anything goes wrong

No, that's why they dim the cabin lights.

Well, no, not easily if the window blinds are down.

Lights dimmed

1. The lights are dimmed to improve the PAX night vision.
2. The lights are dimmed so you and the cabin crew can see out.
3. The lights are dimmed to reduce the demand on the generators and thus improve engine performance if a go around is needed.

Blinds open

1. To allow you and the cabin crew to see the lights outside
2. To allow th eCC to see any problems in the event of an evacuation.
3. To improve the chance of the tower/other aircraft seeing your a/c on the ground (300 lights are better than 3!)
4. To allow the emergency crews to see in before they start cutting your head open in the belief that no-one was leaning on the window.

Mobiles have no effect on the cockpits intruments as the cockpits are so heavily protected from interference anyway that the mobile signals just aren't strong enough. That's why they are allowed on Emirates airlines.

Read back a few pages. It's not that they propbably won't have any effect on the aeroplane, it's the LAW.

The day I turn to the "science" that Mythbusters produce, is the day I hand in my engineering degree and/or let kwikfit work on my car.

Anyone with the slightest knowledge of science and experimentation knows that their conclusions are often at best guess work and at worst total gubbins.

It is an entertainment program not a serious bit of scientific research. Especially the experiments where they cannot reproduce the effects. Just because they could do it, doesn't mean that it is proven one way or the other. That's why they use the "Plausible" ending so often. As they cannot come to any meaningful conclusions, certainly none that the scientific community would ever respect.

If phones affected planes, they'd be falling out of the sky by now.

There are two possible conclusions that can be drawn from this statement:

a) that you haven't even vaguely read, or taken on board, anything posted on this thread.

or...and I'm gradually leaning towards this one...

b) that the spread of bovine CJD through the general population is far more common than previously feared (or at least, admitted to) and that one increasingly pervasive symptom of this is seemingly random acts of utterly demented feckwittery appearing on public forums such as this one, this being a case in point. FFS.

You know, it's funny how, when someone else is enforcing the law, they feel free to disagree with it, but when THEY are, then "the law is the law", and you MUST comply or feel the full force of their wrath.

Nonetheless, this thread is getting nowhere fast. We've established that I must be a very naughty little boy for daring to ask a question of someone who is far too busy to actually deal with me, a paying customer, in an adult fashion. And that, if I continue to ask awkward questions, I will be punished.

We've also established that these devices are all allowed during the flight, just not during take-off or landing. But we knew that already, just not the reason.

And finally, we've established that TP&P is not the place to go for a serious discussion, as Le TVR aside (and a thank-you is due there, in case I forgot previously in the heat-of-argument), no-one has bothered to produce any meaningful information...

Apparantly they are developing some new fangled techhy thing to allow you to use the phone on a plane. Instead of the mast giving a signal out from the ground, there's a server type thing on the plane which all the phones can hook up to, then it works off a satellite.

See ya. One thing, since none of us have produced anything "meaningful" (apart from explaining the thought and rationale behind the rules......) how about you enlighten us with your data on the subject. Obviously you know all about the control systems and how they work and how each single piece of personal electronic equipment on sale today may affect them.

Teach us how we have got it so wrong, just so you can listen to music for 30 minutes............

Havoc,

If I whap out my todger, flash it at old ladies and get caught, I am resonsible for my actions. If I drive at 38mph through a 30mph area and run over a child, I am responsible for my actions.

If you don't want to listen to safety warnings and adhere to the law you might be putting my life at risk by dropping your MP3 player in the aisle. Why? The bit that connects the headphones to the player is made of wire and is long enough to cause a trip hazard and thus less people can get out of the plane.

Health and safety gone mad you say? Nope. Both flight and cabin crew are there to ensure that you get to your destination;
a) On time
b) In reasonable comfort
c) Alive

Just imagine for a second that everyone else on the plane thought the same as you and turned on laptops, nintendos, mp3 players. Now imagine the pilot announcing to people who aren't listening that the plane is about to drop into the Hudson River. Just how many do you think would get out alive?

I'm happy to shoulder responsibility for my actions. Are you happy to accept responsibility for the lives of your fellow passengers?

Thing is, I agree with you. And I hate being told what do do.

That said, it's been explained that

(a) this is a legally-based instruction, which the crew have to enforce
(b) phones really do interfere (a bit) with control systems

On that basis, and also because the only way I'll get to fly is if I submit to these rules, I'll just gently simmer down. I just wish that the CC were a bit more clued up and able to explain the situation better, but then that's like expecting a till assistant to explain Tesco's marketing strategy.

You didn't actually read a word I said, did you? I'm not a pilot, or crew, or anything but a fare-paying joe.

Actually :

You didn't read a word anyone said. There's been plenty of explanation, just you don't like the answers you've been given, so you've summarily dismissed them.
