Find out the real reason to use Airplane mode on your phone

Most of us are familiar with the routines related to air travel and the rules of passenger planes such as that the window blinds must be raised so that we can tell if there is an emergency, the seats must be placed upright and the tables closed in front of us, so that we can exit the row quickly, and mobile phones must be set to Flight mode so you don’t cause an emergency to the plane, right?

According to RT, air navigation and communications rely on radio services, and they have been coordinated to reduce interference between them since the 1920s, and the digital technology currently in use is more advanced than some of the older analog technologies we used even 60 years ago.

Research has shown that personal electronic devices can transmit a signal within the same frequency range within communications and air navigation systems, creating what is known as electromagnetic interference.

But in 1992, the US Federal Aviation Administration and Boeing, in an independent study, investigated the use of electronic devices and interference with aircraft flight systems and found no problems with computers or other personal electronic devices during non-critical phases of flight (takeoffs and landings are considered are the critical stages).

The US Federal Communications Commission has also begun creating frequency bands reserved for different uses – such as cell phones, aircraft navigation and communications – so that they do not interfere with each other.

Governments around the world have put in place the same strategies and policies to prevent interference with aviation. In the European Union, electronic devices have been allowed to remain on while in flight since 2014.

Why then, with such global standards in place, has the airline industry continued to ban the use of cell phones? One problem with something you might not expect is ground interference.

Wireless networks are connected by a series of towers; Networks can become overburdened if passengers flying through these ground networks all use their phones.

And the number of passengers who traveled in 2021 was more than 2.2 billion, which is half what it was in 2019. Wireless companies may have a special view here.

And of course, when it comes to mobile networks, the biggest change in recent years is the move to a new standard. Existing 5G wireless networks, which are desirable for faster data transmission, have worried many in the aviation industry.

The RF bandwidth is limited, however we are still trying to add more new devices to it. The aviation industry reports that the spectrum of 5G wireless network bandwidth is remarkably close to that of the reserved aviation bandwidth, which can cause interference with navigation systems near airports that assist aircraft landing.

Airport operators in Australia and the United States have expressed aviation safety concerns associated with the launch of the 5G network, however it appears that it has been raised in isolation from such problems in the European Union. Either way, it is wise to limit mobile phone use on aircraft while issues with the 5G network are resolved.

Most airlines now provide customers with either paid or free Wi-Fi services. With new Wi-Fi technologies, passengers can theoretically use their mobile phones to make video calls with friends or customers while on the plane.

On a recent flight, Doug Drury, Professor/Head of Aviation at CQUniversity Australia, spoke with a flight attendant and asked her what she thinks about phone use during flights.

She said it would be annoying for the cabin crew to wait for passengers to finish their call to ask if they would like any drinks or anything to eat. On a plane with more than 200 passengers, the service would take longer to complete if everyone was making phone calls.

For the researcher, the problem of using phones on the plane has more to do with the social experience of having more than 200 people on board, all talking together at once.

As disruptive passenger behavior, including “air rage”, increases, the use of a phone during a flight may be another motivator that changes the entire flight experience.

Disruptive behavior takes various forms, from non-compliance with safety requirements such as not wearing seat belts and verbal altercations with other passengers and cabin crew, to physical altercations – commonly known as “air rage”.

In conclusion – the use of phones on board does not currently impair the ability of the aircraft to operate. Cabin crews, however, may prefer not to be delayed due to this use in providing the onboard service to all passengers.

However, 5G technology is encroaching on the radio frequency domain of air navigation systems; We will need more research to answer the 5G question regarding interference with aircraft navigation during landing.
