In fact, the air navigation and communication system was a system designed in the 1920s to prevent interference (beeping in communication channels) during flight. It worked through the radio channel..

In other words, we can say that they tried to cut the interference through this network. Today, however, the technology If you’re wondering why we still have to put the phone in airplane mode on an airplane since it’s much more advanced, here’s why. Senior Aeronautical Engineer Listen to Meriç Kahvecioglu.

In fact, electronic devices can radiate energy at the same frequency as aircraft communication and navigation systems. However, a study conducted in 1992 found that using these devices in flight did not cause any problems for the aircraft (except for landing and take-off).

Employees of the communication committee in America, cell phones and airplane navigation started producing frequency settings specifically reserved for the purpose of this is to prevent the frequencies of both from mixing together. Then other governments around the world are adopting this logic and working on this issue. Interestingly enough, the US has even been known to leave electronic devices fully open during flight for the first time in 2014.

By the way, not putting the phone in airplane mode during flights has not caused a plane crash so far.

This situation cannot cause the aircraft to crash in the future. But in the cockpit, HF or VHF Communication with base stations at high frequencies using antennas can cause radio interruptions or strange noises to pilots (receiver interference). As a result, it is concluded that communication with the tower may not be sound. With the resulting misunderstandings, it is possible to experience situations during the flight that can cause panic. In addition, it can affect the compass indicators, although this is unlikely. Since these compasses are mainly used during landing and take-off, the actions to be taken during landing and take-off become more important.

This is the main reason why electronic devices are still banned on the plane: Parasites

Let’s take a look at the number of passengers that travel more than 2.2 billion around the world. If you ask where this rate comes from, we can say that the total number of passengers traveling by plane in 2021 was around this one. Since wireless networks are also affected by each other’s signals, other cables related to ground flying equipment can become congested when all flying passengers are using their phones. Example 5G wireless network While it is normally preferred for fast data transfer and smooth internet usage, the airline industry does not like its use. Normally, the capacity of radio frequency in aviation communication systems is quite limited.

In other words, you might think it’s incapable of canceling the frequency of everyone’s phone. That is why the range of 5G wireless network bandwidth is quite close to the range intended for the width of the airline network; interferes with navigation systems near the airport and aids in the landing of aircraft. interference The so-called problem is the radio rustle during communication. Takeoff and landing are the most important phases of flight as these are the parts where compasses are most commonly used. Therefore, parasites can occur.

In fact, there was no interference problem before because 3G and 4.5G had no band network close to the airline network. After 5G, the situation has changed for the reasons mentioned above. As a solution to this, it was said that the latest base stations should not be installed near the airport. However, this situation has not yet been resolved.

“What does passenger misconduct have to do with airplane mode?” Don’t say because it is there.

Some airlines offer their customers Wi-Fi service that they can pay as they use or use for free. This allows people to use their mobile phone during the flight. However, the fact that everyone can benefit from this service at the same time is an obstacle to a healthy flight. For example, there are 200 people on an airplane at the same time and everyone is sitting at the same time. to Wi-Fi connects and calls. Imagine that in such a situation, if the cabin crew waited for all 200 passengers to turn off their phones to serve food and drinks, they would have to get up later than the flight time.

Flight attendants say they encountered aggressive behavior from passengers when they told people to turn off their phones during takeoff. Some passengers may also have a fear of flying or a fear of flying. For this reason, they may naturally engage in unpleasant behavior such as not wearing a seat belt, arguing with other passengers, and failing to follow security measures. In other words, the use of electronic devices is not subject to certain rules, and this type of passenger is more likely to be on the plane. Danger can lead to.

But now that the plane has taken off use the phone It is known to have caused no damage to the aircraft. However It is essential to put your phones in airplane mode during takeoff and landing.
