Restrictions on the use of electronic devices including mobile phones in aircraft has been a scourge. But research shows that a ban on a controversial thing.

The study found that passenger planes secretly using a cell phone, play games or listen to an MP3 player during takeoff or landing may not be causing the crash. But maybe they'll just get a rebuke from the stewardess.

Federal agencies and U.S. airlines so passengers do not like such behavior, although researchers and aircraft manufacturers have expressed virtually no direct evidence from mobile phones or other electronic devices interfere with aircraft systems.

Federal Aviation Administration (FAA) requested RTCA, an organization of independent industry standards, to study the problem of electronic devices on airplanes in 1992.

The results found no interference RTCA and recommended the use of laptops, gaming devices and music players. However, the agency recommends preventive measures that prohibit the use of the device during takeoff and landing, which is a critical phase.

Boeing also investigated several cases in the 1990s in which the flight crew reported that a laptop computer or gaming device causes the automatic pilot is not working, aircraft control himself or roll equipment malfunctioning screen.



However, the aircraft manufacturers were never able to repeat their anomalies were reported in laboratory tests.

Mobile and wireless devices like laptops representing different concerns. Device that emits an active transmission of the electromagnetic spectrum, which is used by devices that include telephone, radio and Wi-Fi networks.

But the U.S. Agency Communications Commission spectrum divided into pieces of different for different uses, so that cell phones will not conflict with specific bands for communications or GPS navigation system aircraft.

Prohibition more wireless devices carried out regarding the possibility of interference with the network on land, rather than the dangers associated with aircraft systems.

The FCC prohibits using most mobile phones and wireless devices in flight in 1991, with the reason the network disturbances on the ground. FAA's decision to run the FCC rules.

But some airlines allow passengers to use the phone in airplane mode.

FCC rules ban running, but in 2007 said there was not enough evidence to indicate whether the flight, wireless devices cause interference with ground networks.

All the rules in the world still do not prevent passengers from custom calling from mobile phones. About one in four mobile phones to call in every commercial flight, according to a study in 2006 by Carnegie Mellon University in Pittsburgh.

Funny thing is, even the FAA should advise the aircraft crew to turn off their phones during takeoff and landing, after the incident in early 2009
