New Study, Cell Phones cause problems in cockpit.

The IEEE article is available on-line at

http://www.spectrum.ieee.org/mar06/3069

It says they searched the ASRS database and found some interesing entries.
One in particular:

"In one telling incident, a flight crew stated that a 30-degree navigation
error was immediately corrected after a passenger turned off a DVD player
and that the error reoccurred when the curious crew asked the passenger to
switch the player on again. Game electronics and laptops were the culprits
in other reports in which the crew verified in the same way that a
particular PED caused erratic navigation indications."



(PED = portable electronic device)

Even better is the GA contribution to the cause: (from the same atricle)

"In March 2004, acting on a number of reports from general aviation pilots
that Samsung SPH-N300 cellphones had caused their GPS receivers to lose
satellite lock..."

During that period, the researchers monitored radio emissions from cell
phones and other electronic devices on commercial flights throughout the
Northeast. The equipment used to take the measurements, including a laptop
computer, had been modified for safe in-flight use and fit in a nondescript
carry-on bag.

They did not say (at least in the newspaper article) that they studied
the =effect= of those emissions on cockpit instrumentation... just that
the emissions existed. One may infer from the paper's conclusion that
it was studied, but that would be an inference by the reader. The
conclusion may in fact be unjustified.
