We all know the routine at the heart: “Please make sure that your seats are in honest position, tray tables are, window shades up, laptops are stored in overhead compartment and electronic devices are set on flight mode.”

Now, the first four are appropriate, right? Window shades need to be up to see if we can see if there is an emergency, such as fire. The tray table needs to straighten stoves and seats so that we can get out of the row quickly. Laptops can become a projectile in an emergency, as seat back pockets are not strong enough to contain them.

And the mobile phone needs to be set in flight mode so that they do not cause emergency for airplanes, right? Well, it depends on whom you ask.

Aviation depends on navigation and communication radio services, which is coordinated to reduce intervention From the 1920s,

The currently used digital technology is much more advanced than some old analog techniques we used by 60 years ago. Research has shown that individual electronic equipment can emit a signal within the same frequency bands as the aircraft communication and navigation systems, known as electromagnetic intervention.

But in 1992, US federal aviation authority And in boing, Independent studyChecked the use of electronic devices on the aircraft intervention and found no problem with computer or other individual electronic devices during the non-mating stages of the flight. (Techoff and landing are considered an important phase.)

The US Federal Communications Commission also began creating reserved frequency bandwidths for various uses – such as mobile phones and aircraft navigation and communication – so they do not interfere with each other. Governments around the world developed similar strategies and policies to prevent problems of interference with aviation. In the European Union, there are electronic equipment Allowed to stay on Since 2014.

Then, with these global standards, has the aviation industry continue to ban the use of mobile phones? One of the problems lies with something you cannot expect – Field Interference.

Wireless networks are connected by a series of towers; If the passengers flying on these ground networks are using their phones, the network may be overloaded. Number of passengers flying in 2021 It was more than 2.2 billion, and half of the 2019 passenger numbers. Wireless companies may have a point here.

Of course, when it comes to a mobile network, the biggest change in recent years is a step for a new standard. Current 5G wireless network – desirable for their high speed data transfer – has created concern for many within the aviation industry.

Radio frequencies bandwidth is limited, yet we are still trying to add more new devices to it. Aviation industry states that 5G wireless network bandwidth spectrum Noticely reserved aviation bandwidth is close to spectrum, which may be the reason Interference with navigation system near airports It helps in landing the aircraft.

Airline officials worry about your 5G network of your cellphone. Why is here (2021)

Airport operator in Australia And America Aviation safety concerns related to 5G rollouts have voiced, although it seems to roll without such problems In the European UnionEither way, it is prudent to limit the use of mobile phones on aircraft, while issues around 5G are resolved.

Most airlines now provide Wi-Fi services to customers which are either Pay-A-U-Go or Free. With new Wi-Fi technologies, passengers can theoretically use their mobile phone so that video calls with friends or customers.

Recently on a flight, I spoke with a cabin attendant and asked his opinion on the use of the phone during flights. He said that it would be an inconvenience to wait for the passengers for the cabin crew to ask them if they would like to eat any drinks or anything. On an airliner with 200+ passengers, the in-flight service will take longer to complete if everyone was making a phone call.

For me, the problem with the in-flight use of the phone is more about the social experience of having 200+ people on an aircraft, and all are speaking at once. At a time when disruptive passenger behavior, including “air raj”, is becoming increasingly frequent, the use of the phone in the flight may be another trigger that changes the entire flight experience.

Disruptive behavior takes at various forms, from non -non -aviation to security requirements such as not wearing seat belts, oral changes with fellow passengers and cabin crew, for physical changes with passengers and cabin crew – are usually identified as air rases.

Fone’s in-flight uses in conclusions do not inhibit the aircraft’s ability to operate. But the cabin crew cannot delay all passengers providing in-flight service-this is to serve many people.

However, 5G technology is encroaching on the radio bandwidth of the aircraft navigation system; We will need more research to answer 5G question Regarding intervention with aircraft navigation during landing. Remember that when we are discussing two most important stages of flight, takeoff is optional – but landing is mandatory.
