This is NOT UA specific, but is brought up so often on this forum (the only 1 I read) so I will post here, and if the Mods move it to OMNI or wherever, so be it.

Seems Carnegie Mellon did a study and cell phones DO disrupt navigation equipment...


From USA Today..

"Granger Morgan, head of Carnegie Mellon's Department of Engineering and Public Policy Department, said the activity recorded shows that the use of electronic devices should be limited on airplanes.

Morgan said the disruptions are enough to impact a plane's navigation or other systems."
