Notebooks in flight

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.

One notebook maybe, but 50 to 100 could cause some beat frequency
problems with the avionics.

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.

Not asking about your state of mind here.
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.

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.

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.

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

Weak argument, put away your 10 ounce cell phone, but you can carry on
reading your 2 lb book.

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.

Not quite true Chris, just have a look at the NASA website
for information on how 'consumer electronics' have intefered
with avionics systems.
