The potential for interference from a mobile phone does not only exist when it is in use, but also when it is idle, which is why cabin crew ask passengers to use airplane mode.
Smith estimated that despite the clear request at the start of each flight, “at least half of all phones, whether inadvertently or through laziness, are left on during the flight”. But he added that if motives were such a big concern, the policy would be enforced more actively.
Cell phone use was only mentioned as a possible factor following a major air accident: a Crossair crash in Switzerland in 2000. electromagnetic interference (EMI)” from cell phones.
Even though mobile use is not safety critical, it may still inconvenience your pilot. And when the cockpit should ideally be a place of calm and serenity, it’s not ideal. Addressing the issue, The Points Guy quotes a private pilot, Nikita Schmidt:
“Your phone is probably going to annoy a few pilots and air traffic controllers. But, most likely, not enough for them to take action against you, if that’s what you want to know.
“You may have heard that unpleasant noise from an audio system that sometimes occurs when a cell phone is nearby. The radio emissions from a phone can be very loud, up to 8W; they cause this noise due to spurious demodulation. In fact, I heard such a noise on the radio during the flight. It’s not safety critical, but it’s annoying for sure.
“Of course, there is a lot of attenuation between the phones in the cabin and the pilots’ radio. However, if for example 50 people on board are inconsiderate enough not to bother turning off their cell radios, There will be 50 phones constantly searching for cell towers at maximum power.That’s a lot of radio pollution.
“When in-flight cell service is provided, there is a cell station right next to these phones. They communicate at very low power without causing disturbances. The Wi-Fi signal is much weaker (100mW) than GSM at its peak, and I’ve never heard of it causing any issues.
So in the current system, phones have the potential to interfere with the flight crew, but only to a small, albeit annoying, degree. And when airlines offer 5G in-flight, that shouldn’t be a problem.
Nevertheless, as Smith points out, there will be social implications.
“As soon as it can be proven beyond a reasonable doubt that the phones are safe, a percentage of flyers will demand the right to use them, pitting one group of angry travelers against another, with carriers stuck in the middle” , did he declare.
“The airplane cabin is a last refuge of relative silence. Let’s keep it that way. We are inclined to agree.
