Airplane mode is something you may have spotted in the control center of your phone, But what exactly is Airplane mode? And when should it be used?
Well, airplane mode addresses a problem caused by the growing popularity of modern electronics. This feature is not limited to Smartphones only. It is also found on computers, tablets, iPhones, Smartwatches, Readers, and even notebooks.
It all started in the 90s when mobile phones became popular. Airline pilots began to hear clicking noises in their headsets. They discovered that the sound was caused by transmission signals from passengers’ cell phones as more people brought phones onto flights, the more interference pilots heard. In response, Airlines began banning the use of cellphones on planes. Forcing passengers to turn their phones off completely, or leave them at home.
But as phones became smarter, manufacturers were able to create modems that turned off transmission signals. Allowing phones to be used on flights without a cellular connection. This new capability was called Airplane Mode. And it remains an important feature of modern devices. Since Smartphones like an iPhone and Androids don’t have to be turned off during a flight, and can even be used with WIFI turned on. Since it uses satellite signals instead of radio signals. Giving passengers access to texting, phone calls, and even video streaming while flying. This would have been unimaginable in the 90s. But despite airplane mode being a federal requirement in US domestic flights, 29% of passengers admitted that they had forgotten to enable the feature at least once while flying in 2021.
And while there hasn’t been a recorded plane crash caused by interference from transmission signals, they do pose a serious risk. Planes have radio altimeters that measure their height from ground data from this sensor is used by pilots during landing to ensure a safe touchdown.
Especially when visibility is low due to fog, snow, or other bad weather. So while maybe inconvenient, Airplane Mode is an essential feature. Allowing passengers to continue using their phones on a plane, while also ensuring the safest flight possible.
