![]() The wireless companies might have a point here. The number of passengers that flew in 2021 was over 2.2 billion, and that’s half of what the 2019 passenger numbers were. Wireless networks are connected by a series of towers the networks could become overloaded if passengers flying over these ground networks are all using their phones. (Takeoffs and landings are considered the critical phases.) ![]() Research has shown personal electronic devices can emit a signal within the same frequency band as the aircraft’s communications and navigation systems, creating what is known as electromagnetic interference.īut in 1992, the US Federal Aviation Authority and Boeing, in an independent study, investigated the use of electronic devices on aircraft interference and found no issues with computers or other personal electronic devices during non-critical phases of flight. The digital technology currently in use is much more advanced than some of the older analog technologies we used even 60 years ago. Technology has advanced a great dealĪviation navigation and communication relies on radio services, which has been coordinated to minimize interference since the 1920s. Laptops can become projectiles in an emergency, as the seat back pockets are not strong enough to contain them.Īnd mobile phones need to be set to flight mode so they can’t cause an emergency for the airplane, right? Well, it depends whom you ask. Tray tables need to be stowed and seats upright so we can get out of the row quickly. Now, the first four are reasonable, right? Window shades need to be up so we can see if there’s an emergency, such as fire. Battery life saved this way may vary by phone, but using Airplane Mode on a plane may last a bit longer after landing.We all know the routine by heart: “Please ensure your seats are in the upright position, tray tables stowed, window shades are up, laptops are stored in the overhead bins and electronic devices are set to flight mode.” In case you didn’t know, wireless signals drain a phone’s battery faster, so airplane mode helps extend battery life. He said that if the radio altimeter’s functions are affected, that is, it cannot tell precisely how far the aircraft is from the runway, the results can be disastrous. But unfortunately, it can be dangerous if something goes wrong, so avoid doing it.Īccording to pilots, radio altimeters are used to determine the correct altitude of an aircraft during flight, especially in areas where visibility is reduced due to fog, snow, or bad weather. If you forget to switch your phone to airplane mode during a flight or do it on purpose, the chances of major damage are negligible.

That is why pilots tell people to switch to airplane mode, especially before the plane takes off and lands, so there are no problems. These signals can affect aircraft transmissions, especially if there is an emergency where the pilot needs a simple line of communication to communicate with air traffic control, but telephone signals can affect that communication. And as mentioned above, mobile phones and tablets use similar signals. Aircraft communication and navigation systems use radio frequencies emitted from the surface and are more likely to interfere with radio signals. ![]() The reason for this is not simple but simply put, airplane mode does not allow any potential interference with sensitive aircraft systems.

So what is the purpose of this directive, and why are airlines doing it? What is airplane mode?Īirplane or flight mode temporarily suspends smartphone signals and Wi-Fi signals, but other functions continue to work. If you’re traveling by plane, you’ll often hear flight attendants tell you to switch your phone to airplane mode. But what is its purpose, and if we do not use this mode on aircraft, can there be any significant damage? What can happen if we do not use airplane mode while traveling on a plane? Do you know its purpose? Many people use smartphones now and have seen airplane or flight mode.
