Cell phones do not disrupt navigation systems
Tests by Airbus and American Airlines /Qualcomm indicate that, contrary to popular lore, cellular signals do not disrupt airplanes' navigational systems. The two results were similar for both the CDMA and GSM cellular technologies, but the Federal Aviation Administration and the Federal Communications Commission say the tests can't officially be considered in their review of the rules because they were conducted without government oversight. The agencies say they are moving ahead with their own tests (Wall Street Journal 23 Sep 2004)
