As of 2012, most airlines do not allow the use of mobile phones on aircraft. Those that do often ban the use of mobile phones during take-off and landing.
In the United States, the use of mobile phones and similar devices on airborne aircraft has been banned by the Federal Communications Commission.
Reports exist which assert correlations between the use of mobile phones (and other passenger electronic devices) in flight and various problems with avionics. One study concluded that mobile phones used in the cabin could exceed the aircraft manufacturer's rated allowable emission levels for some avionics. On the other hand, causal relationships between device use and these failures have not been established statistically. All reported incidents to date have been difficult to reproduce in tests.
In the time since the regulations were originally imposed by various international agencies, equipment such as pico-cells has been developed with the intent of allowing safe in-flight use of mobile phones. Some airline companies have now added such equipment to their aircraft. More are expected to do so in the coming years.
Famous quotes containing the word mobile:
“From three to six months, most babies have settled down enough to be fun but aren’t mobile enough to be getting into trouble. This is the time to pay some attention to your relationship again. Otherwise, you may spend the entire postpartum year thinking you married the wrong person and overlooking the obvious—that parenthood can create rough spots even in the smoothest marriage.”
—Anne Cassidy (20th century)
