'[EE]: existing airliners will be tested for rfi co'

Using cell phones:

<http://money.cnn.com/2004/12/09/technology/personaltech/cellphones_inflight/index.htm?cnn=yes>

Let's see, 150 of 300 passengers have their phones on, with about 0.6W
each (is this correct ? - assume the cell repeater is not ok and power
feedback fails) in the body of the plane which reflects and conducts this
rfi towards/through/into aircraft systems some of which are 30 years old.

   A fiery death in a crash caused by all that RFI would likely be
   a welcome relief for the passengers who would otherwise be forced
   to listen to 150 idiots yelling into their cellphones for 3000
   miles.

   Stupid people who think lifting the cellphone ban is a good idea
   should be in favor of lifting the in-flight smoking ban, too.

I agree wholeheartedly. A mistuned cellphone caused by a weak battery,
maybe?
I am uncomfortable when anybody uses a cellphone on a plane, even when
it is still
at the terminal.

The problem is that nobody really needs to talk. If the cell relay in
the plane goes crazy or loses power at a critical moment it can cause
all the phones to send channel seek handshake packets at essentially the
same time, repeatedly.

Indeed!  Not to mention the cacophany of ringtones...

Let's hope the FAA decide that it's too dangerous (and
that the CAA ignore this whole thing and leave things as
they are!).
