Why exactly are you not allowed to use a notebook computer during take- off and landing? The radio power emitted by a notebook should be too weak to cause any problems to the plane electronics.

They don't want you distracted by your notebook/iPod/Nintendo DS/whatever if there's an emergency and you have to get out in a hurry. > Why exactly are you not allowed to use a notebook computer during take- > off and landing?

Baloney. This has been proven to be completely false again and again. More than likely, they are concerned someone would get injured if they suddenly had to stop and don't want to be liable. It has nothing to do with electronics. >>> Why exactly are you not allowed to use a notebook computer during take- >>> off and landing?

They, the people who really know, require that all electronic devices be powered down during the landing and take off phases of the flight. They don't want to take chances with passenger's electronics that may not be assembled and tested to FCC/FAA standards, including radiation hardness. >>>> Why exactly are you not allowed to use a notebook computer during take- >>>> off and landing?

Sure and cellphones do the same thing according to the same ones that believe this. Also, having been proven to be completely false. The reason, as everyone else knows, is to prevent liability for these things flying around the cabin in case of a sudden stop. >>>>> Why exactly are you not allowed to use a notebook computer during take- >>>>> off and landing?

For years the airlines have been telling people to keep their cellphones switched off at all times while on board the aircraft. Now that they've found a way to make extra money by allowing passengers to use their cellphones in flight, these things will suddenly be deemed quite safe to use.

I don't know, but cellphones had previous been disallowed at any time on aircraft on the basis that they were a risk to flight systems. The point is that now that the airlines have discovered they can make money from their use, they are apparently no longer considered a danger.

Are you saying that they are less dangerous when they are switched off? And exactly how dangerous is my Nanopod as a flying object?

The only "people who really know" are those who have carried out actual tests, and so far those tests have failed to show any adverse effects from using notebook computers. Those who make these rules are "people who don't really know", so they just err on the side of caution. Chris >>>>> Why exactly are you not allowed to use a notebook computer during take- >>>>> off and landing?

But not as far as keeping them from flying around the cabin. That's a valid issue. >Chris >> Why exactly are you not allowed to use a notebook computer during take- >> off and landing?

Not really. For example, think about the WN flight that overshot the runway at MDW. If 30 people had laptops out for use, they would have had 30 missiles streaking through the cabin. (Among other things.) never a problem with laptop or GPS in my plane and anything I bring on board, laptop, cell phone, gps, etc sits right in front of the avionics on any airliner, you are usually a minimum of 10-15 feet from the cockpit unless you are on a "puddle jumper" or Dash aircraft. can you walk and chew gum ?? Pilots do that all the time{ 1) talk to ATC 2) watch out for traffic 3) control the airplane 4) navigate >> Why exactly are you not allowed to use a notebook computer during take- >> off and landing?

Kulp was one of those infants who flew through the cabin on a sudden stop. Landed on his head. They had to remove his tongue, but the doctors replaced it with his sphincter.

During take offs and landings? Or just during flight? During take off and landings, they'll require you to stow everything. Most of the airlines are making a point to tell you that laptops in the seatback pouch is not allowed either. If you watch, you'll also see the FA's taking purses and other items from people in the bulkhead seats. They tell them the items have to be stowed for takeoff & landing, but they can remove them from storage during the flight. > On Nov 19, 1:54 pm, DevilsPGD <spam_narf_s...@crazyhat.net> wrote: >> In message <MPG.238dd7deb697be498b...@news.supernews.com> Alfred Molon [quoted text clipped - 19 lines] > for takeoff & landing, but they can remove them from storage during the > flight.

What kind or > airline do you fly with? Sorry, I've seen this happen with bulkhead (i.e., very front row) seats on _many_ occasions -- in fact, I'd say, near universally, whenever there is no seat and hence no "space under the seat" in front of you. The cabin crew will more or less universally require that computer bags, briefcases, backpacks, maybe even sizable purses, anything down by your feet, be stowed overhead during takeoff and during landing. If you happen to have a small laptop out in flight, and there's a sizable pocket for magazines on the wall in front of you, you may be able to get away with stowing the laptop in it, or hiding it beside you, down next to the arm rest -- or maybe even hold it on your lap -- and you may be able to get away with not stowing it; but if they see it (and they do look carefully), it'll have to go overhead. >>> If you watch, you'll also see the FA's taking purses and other items from >>> people in the bulkhead seats.

We have flown bulkhead seats many times, and on different airlines, and every time without exception the flight attendants have taken our bags and purses, and stowed them in the overhead bins during take off and landing, gets a bit paranoic for ladies to be separated from their handbags, but everybody is strapped in anyway. never had any problem. I will put the laptop on the floor or put in a bag and put behind my legs if I have to... On planes, I need to remember to kick out or disable my network card or as it will continiously try and find a network much like a cell phone will keep looking for a cellular tower >>>> If you watch, you'll also see the FA's taking purses and other items from >>>> people in the bulkhead seats.

I was once on a military flight where a high-ranking military officer insisted on standing during the take off and landing. No one was going to tell a "three star" to sit down but I think it would have been funny if the plane had blown a tire and thrown him through the window. When a plane is taking off or landing you are supposed to be strapped in with your tray table and seat back up and not messing with anything that could cause injury if "stuff" happened. It would be just my luck to be sitting in front of or behind Alfred when the plane took a bounce and have his laptop ricochet off the overhead and come down on top of me. Also, while a *properly functioning* laptop might not cause any problems with the plane's electronics, you should not attempt to assert that an improperly functioning one would never do so. During take-off and landing there is no time to look for and isolate the source of a problem. It's best to be safe. I'm just glad they let us use them at all. SignatureDonald R.

I'm just glad they let us use them at all. I don't think the plane's electronics is a problem, if anything it might be the RF noise interference making voice communication more difficult for the pilots. Aircraft radio still uses AM modulation. >>> Why exactly are you not allowed to use a notebook computer during take- >>> off and landing?
