    Using a cell phone on a plane interferes with the navigation and communications systems of the aircraft

    "I've never experienced a navigational problem that could be traced to a cell phone," says one veteran pilot who didn't want his identity revealed. "From everything I've read, cell phones and most avionics shouldn't conflict."

    So why do flight attendants make you put away your gear before takeoffs and landings? "That's more for making sure [we] have people's attention and for [individual] safety," he says. "If I have to hit the brakes and abort a takeoff, I don't want a laptop flying across the cabin."

    The Federal Aviation Administration, which regulates cell phone use in a plane, has a different view: "The concern is that cell phones would conflict with onboard avionics," says Paul Takemoto, the FAA's electronics guru.

    Is there scientific proof that cell phones can make planes go haywire? Some. In 2003 the Civil Aviation Authority--the FAA of the United Kingdom--ran tests using simulated cell phone signals in a chamber (not in an actual aircraft) and found problems. In some cases, the compass froze, some instruments displayed errors, and audio communications were difficult to hear due to interference.

    Until additional tests prove otherwise, Takemoto says, the FAA prefers to err on the side of caution.
