When we’re about to catch a flight, we usually repeat the usual routine: people queuing to show board, ID and boarding pass, reminded of what can’t be found on the plane, queue to board the plane, find our seat, leave the bag in the upstairs compartment and sit down And put on your seat belt.
then they start Aircraft Customs, We know them by heart. Windows with blinds, tray closed… and one of the most famous, if not most, reminders to turn off mobile devices or leave them in airplane mode.
In fact, smartphones need to be set to Airplane Mode so they can’t cause emergencies on the plane, right? Well, technology has come a long way, especially in recent decades. So, it depends who you ask.
Aviation communications depend on radio services, which have been coordinated since the 1920s to reduce interference. The digital technology used today is much more advanced Compared to some of the older analog technology we used 60 years ago.
Research has shown that personal electronic equipment can emit a signal within the same frequency band as aircraft navigation and communication systems, a phenomenon known as electromagnetic interference.
but in 1992An independent study by the US Federal Aviation Authority and Boeing examined the use of electronic devices to jam aircraft and No problems with computers or other personal electronic devices were found in flightTakeoff and landing do not count.
Therefore, from the United States they were created to reserve frequency bandwidth for various uses such as mobile phones and navigation and aircraft communications, so that they would not interfere with each other. A strategy that was followed all over the world. In the European Union, electronic devices have been allowed to remain operational since 2014.
So why, even with these, the aviation industry continues to ban the use of mobile phones? One of the problems is something you might not expect: Interference field.
are connected by a series of wireless networks Torres, And if passengers flying on these terrestrial networks use their phones, the networks can become overloaded.
Of course, when it comes to mobile networks, the biggest change in recent years is the rise of wireless networks. 5G, desirable for their high speed data transfer. But they have caused concern among many within the aviation industry.
From the aviation industry, he points out that the bandwidth spectrum of 5G wireless networks is remarkably close to bandwidth spectrum Reserve aviation, which can interfere with the navigation systems near airports that assist with aircraft landing.
This is why most airlines now offer customers Wi-Fi services that are pay-per-use or free. with new technologies Wi-FiPassengers can theoretically use their mobile phones to make video calls with friends or customers during the flight.
Other problems that usually happen to us during a flight
Air travel has increased significantly this year, as has Question in minutes or a few hours we manage to move place Relatively Distant To travel by car.
However, while traveling long Duration one in planewe will see that we swell las feet, It is caused by sitting your feet on the ground for a long time, the blood accumulates in our legs and the pressure increases, causing swelling in the feet and legs. This can sometimes happen while inactive during flight, because it is put back on when we resume our activities such as walking. Spreading Our sangrewithout causing major problems.
In the case of being a person who often makes long trips, camper class syndrome may develop, which includes developing a thrombosis venous Deep, This is due to the increase in the size of the blood clot after sitting for hours.
