So can someone explain to me why my ipod harms the takeoff of an airplane...i am not attempting to say that my ipod does NOT harm the take off, all i am saying is that if my ipod does, do i really wanta fly anymore???
This all stemed from a recent flight from RDU-STL via CLT...on the RDU-CLT i had my ipod in my hands and it was off...i did have my headphones on but it was off. in any case before take off they said to power down all devices.. as the FA walked through the cabin he said to me "sir thats supposed to be off, please trun off your ipod" i said "it is off" "he said can i see it" so i showed it to him and then closed my eyes for a quick nap...
why did he make such a big deal out of it anyway? i mean i did say it was off, why not trust me? and secondly what is the harm even if it was on?
thanks and sorry for the backlash i might get from asking such a simple quest.?

Quoting UAalltheway (Reply 1): According to FAA and airline policy/law it could interfere with you hearing crewmember instruction if an emergency should happen after take-off.
ahhh.. i get it, as if whatever might have caused the emergency landing might not be loud as he*l in and of its self... (joking)
j/k- i was just unsure if it caused some type of mechanical problem. thanx

I'm not much of a poster here on this board but I would like to chime in here: unfortunately some people ruin things for the rest of us and do not follow the rules. They'll say something is off yet it isn't. Hence asking you if they could see your iPod. That's the way things are in this society. Certain people act so irresponsibly that it ruins things for the public at large. I'm sure you had your iPod off but I'm sure that flight attendants have to check everything thoroughly. As far as how an iPod effects takeoff and landings, I'd like to find this out as well. My only theory is that some devices CAN cause interference with devices that the pilots need to fly the plane, so they don't take any chances and prohibit a wide range of devices.

yeah i understand and it was off...but i'll be damned if they didnt have us board 45min late and then we sat on the plane for ages before rolling back, all along i am thinking "i could have dame-it drove to charlotte by now"..adn more reason for me to listen to some tunes.. thanks for the thoughtful post all..

As mentioned before, there was no way the F/A could have known this. I have seen people lie about this all the time.
Quoting Aviation (Reply 5): Beacuse Airlines make money if you buy their headphones for their in flight "entertainment".
Huh? That isn't even relevant to this subject, especially since there was no IFE on this flight.

The lights actually depend on the airline. For instance, AA keeps the light on during take-off and landing. However, most airlines do not. Interestingly, if the airlines go against their specific policy, then they would be breaking the law.

Believe it or not, the magnetic fields generated by portable electronic devices can interfere with the avionics in airliners.
Don't get me wrong, you aren't going to cause the aircraft to instantly burst into flames by listening to Brittney Spears on your IPod, but you can interfere with VHF radio communication and navigation signals if you happen to be sitting in the right spot in the airplane. This effect is especially important under 10,000 ft, because below this altitude airliners may be utilizing VHF navigation signals. Above this altitude, FMS based navigation is employed (utilizing a GPS or inertial reference system).
I have personally witnessed the effects of cellphone signals on avionics. There is a very audible noise that transmits through the headsets in the cockpit when a telephone on board recieves a call in flight. Certain tests have shown that portable electronic devices can have a similiarly negative effect on the accuracy of VHF navigation signals.
Granted, aircraft manufactures should be imporving the avionics' resistance to this type of interference so hopefully someday soon it will be possible to use cellphones and other devices without potentially interfering with comm/nav signals.
Hope this helps to provide some justification for the rules.

On both Frontier and jetBlue, which I've flown and both which feature PTV's, the PTV's are left on following the safety demo and are on and useable during taxi and takeoff, as well as landing...to listen to them obviously involves using headsets, so Im not too sure if there's a specific reg banning the use of headphones during taxi/takeoff/landing

The regulations cover personal electronic devices. The PTVs are part of the aircraft and not personal electronic devices.

As pointed out, its a pure safety issue, and if you refused to comply with such a simple request not to listen to them for takeoff or landing, and had been personally asked after the PA, and you still listened to them, I would most probably get you met at the gate, possibly arrested, and banned from flying with the airline again.
Because the industry is so safe, passengers often think their little change will not effect the outcome in an emergency, or cause an emergency, I don’t know if it will either. However I am lot going to experiment during an emergency with my life, other passengers lives, and your life. I want everything going my way before an emergency presented.
I also get very annoyed at passengers who move their seat backs after takeoff while the seat belt sign is still on, or undo their seat belts and stand up as we are getting closer to the gate. Both can turn into emergency situations so quickly.
Quoting KAUSpilot (Reply 9): Believe it or not, the magnetic fields generated by portable electronic devices can interfere with the avionics in airliners.
The jury is still out on that, and a the extent of interference if any is common misconception amongst the public. I will use this misconception to my advantage at times when passengers fail to listen to simple PA or requests from cabin crew. Something like " Ladies and Gentleman we seem to be experiencing some interference to our navigation equipment which could effect the safety of out flight, if you have any electronic equipment on we ask that you immediately turn it off". You should see the speed at which passengers nearby tell them to turn it off thinking they will crash.

Obviously...that's not what I was talking about...the issue is the fact that the headphones required to properly use the PTV and the facecould be a safety issue during taxi/t.o./ and landing...

Oh there's no doubt that they can and do cause interference. However, you usually have to get the device very close to the avionics equipment itself before it is noticeable (i.e., in the cockpit). There are various antenna and wiring for avionics which pass through the cabin in close proximity to passengers.

Kind of like that Turkish? Captain that after the usual "remain seated until the aircraft has come.....and The Captain has turned off the fasten seatbelt sign" announcement that slammed on the brakes and said, "Glad you were buckled up"

AFAIK, NW's DC-9s don't have an INS, it's VOR navigation all the way, and I've been allowed to use my CD player and laptop while in cruise on them.

I'm not disagreeing with you but I have a funny story. There's a guy I know who's an A320 captain with UA based out of SFO. Earlier this year I was contracting at a place right under the approach path to the 28s near SFO and I told him I always wondered if he was flying one of those planes I'd see on approach every day. He told me, "Give me a call on my cell phone--if I'm flying over I'll answer it." A bunch of people were sitting around when he said that and we all laughed, however, he was serious. As far as he was concerned it wasn't a problem.
As for me, I'll listen to the flight attendant.

The idea is at above 10,000 ft, if they experience problems with navigation, they'd announce that all electronic devices must be shut off, and they'd be able to correct any problem caused by the navigation problems manually, and/or before impacting another aircraft/object.
Below 10,000 ft, they are landing, or getting ready to land. Interfearance during this time could be a bad thing. If you're on final and the glideslope indicator jumps around, and the plane is on autoland, it wouldn't be fun.

But does it matter that iPods don't transmit anything?
Also... I had heard the cellphone thing was caused by the old "analog" cellphones which occassionally could screw up a TV/Radio reception on land as well. Are the newer (since say 1999-2000-ish) cellphones that are digital causing the same effects?

I would agree, I would almost guarentee every flight I do at least one passenger and/or crew memeber will have left their phone on in the carry on luggage.
I have more problems with passengers boarding the aircraft still on the phone whilst we are refuelling, that is a bigger safety concern for me.
