Why Can't You Use Your Cell Phone on an Airplane?

In 1991, the Federal Communications Commission (FCC) banned passengers from using their cell phones while on board an airplane that is in flight. The ban was instituted because the FCC suspected that the radio frequency emitted by cell phones could malfunction an airplane's equipment systems. In complying with this rule, different airlines have instituted different policies about when phones can be turned on and off. In 2005, the FCC announced that it might consider lifting the ban on the use of cell phones on airplanes, with certain restrictions.

The FCC regulates the use of all electronic devices, including cell phones, on airplanes under the assumption that they may affect the communication systems on board. The Federal Aviation Administration (FAA) agrees with the FCC that cell phones may cause substantial interference with aircraft systems and supports the ban for all commercially operated airplanes. The use of cell phones on private or charter planes is not regulated, however, and many private flights permit passengers to use cell phones while in flight.

Lots of debate has surrounded the use of cell phones on airplanes. The primary concern is that cell phones may interfere with the navigation and communication systems of the plane, potentially resulting in devastating failure. Numerous airlines have reported disruptions in cabin pressure, compass function, and wireless navigation systems associated with the use of cell phones on board. The FCC, it seems, erred on the side of caution when it enforced an outright ban on the use of radio frequency emitting devices which could potentially cause an aircraft to crash.

There have also been some reports that the use of cell phones on planes may cause disruptions in ground communications because of interference. Others claim that the airlines and the FCC would simply prefer that consumers use the telecommunications systems mounted on most seat backs in commercial airplanes, because these phones are said to be highly profitable. Newer cell phones are capable of operating on very low power settings, which may not interfere with the aircraft as much. The FCC is attempting to establish an acceptable threshold of radio frequency emissions, so that cell phones could be used on airplanes without any fear of the navigation system failing or service on the ground being disrupted.

Let us have a look at what has happened in India at Mangalore a few days back.

This is what Thomas Dominic has found out and written in Khaleej Times on May 26 about why the accident ever happened at all and I would like to thank him for this.

It’s easy to blame the captain of the ill-fated Air India Express for the tragic accident that occurred in Mangalore, since he is not there to defend his case. Also, one can blame the airline management for not maintaining the aircrafts.

However, I would request all the airline passengers to do an introspection of their role on board, and the readers to consider the following facts before handing over the death penalty. The state-of-the-art plane (B-737-800) was inducted on January 15, 2008. Hence, one cannot say that its conditions were so bad.

Every day, 32 domestic and international flights operate from Mangalore airport. Hence, one cannot caregorically say that the airport or its runway were not safe for landing.

Fifty three-year-old Captain Zlatko Glusica who died in the crash had 10,200 hours of flying experience and his licence had been endorsed by the Directorate of General of Civil Aviation, India. The commander had flown in and out of Mangalore airport at least 19 times, while the co-pilot had operated 66 times from the same airport.

So the pilot and co-pilot were fully familiar with landing at Mangalore Airport, and therefore it’s not right to put the blame on the pilots. Further, the commander did not report any malfunction before landing, to the Air Traffic Control (ATC).

Visibility at the airport on the day of the accident was six km, ‘which is more than that required’, when the ill-fated plane landed in Mangalore.

So then, what could be the reason for this air crash? Possible malfunctioning of the navigational system during the landing process caused by a cell-phone switched on by an ignorant passenger? I have noticed that many passengers switch on their mobile phones while landing as if they are in a race to inform their arrival. It is also possible that someone did not switch off the mobile phone while taking off from Dubai, despite being warned by the cabin crew, and it started searching for signals as the flight descended at Mangalore airport, which could have interfered with the functions of the landing system?

It should be noted that all three recent air crashes — the first one at Russia killing the Polish Prime Minister and his team, the second one at Libya last month and now Air India Express at Mangalore — all occurred while trying to land, thereby strengthening my suspicion about the possible interference in the navigational system by cell phone signals. Any takers?

Do you agree with what Thomas has said or do you think there is more to it than meets the eye?
