Why do you need to turn on airplane mode when flying?

It’s common knowledge at this point to put your phone or tablet on airplane mode before takeoff. But have you ever wondered why flight attendants insist you switch your phone to airplane mode before takeoff?

Believe it or not, it's not just a pesky rule to interrupt your scrolling; there is a reason why regulations still require all passengers to use airplane mode while in the air. Whether you're a frequent flyer or an occasional traveler, understanding the importance of airplane mode can make your journey safer and smoother. It can also help your phone. Here are some of the whys and science behind airplane mode.

Understanding airplane mode

To understand why we’re asked to comply with federal regulations regarding airplane mode, here is a rundown of what it is and why it’s important.

What is airplane mode and what does it do?

Airplane mode is a setting on your mobile devices that disables all wireless

communication features. When airplane mode is on, your device stops sending or receiving radio and cell signals, effectively cutting off cellular data, Wi-Fi, Bluetooth, and Global Positioning System (GPS) connections.

Devices affected by airplane mode

Airplane mode affects various electronic devices:

• Smartphones
• Tablets
• Laptops
• E-readers
• Smartwatches
• Portable gaming devices

The real reason to use airplane mode while flying

It’s a safety thing. Cell phones, laptops, handheld gaming systems, e-readers, and other devices emit radio waves that can affect navigation and radar equipment and interfere with pilots’ headsets. According to Federal Aviation Administration regulations, all passengers are required to use airplane mode while in the air to prevent interference. Plus, it's common courtesy to your fellow passengers.

What happens if you don't turn it on?

When smartphones and devices were first introduced, it was found that cell phones that aren't in flight mode can overload the networks on the ground, especially during takeoff and landing, as phones try to connect to multiple towers at once.

How much phones affect aviation technology hasn’t been studied in-depth, but pilots say they can hear background noise and interference from phones while flying, especially when they’re landing, and mobile phones begin to make contact with towers again. So, while your phone may work at times during flight, do you really want to distract your pilot while they’re speaking with air traffic control to execute a safe landing?

If you don't activate airplane mode during a flight, your device will continue to search for cellular signals, potentially interfering with the aircraft's communication systems. This can lead to:

• Disruption of aircraft navigation systems
• Interference with pilot-to-ground communication
• Possible safety risks for the flight
• Your device’s battery will drain faster

How to activate airplane mode

Turning on airplane mode is easy. Here’s how:

1. On most smartphones, swipe down from the top of the screen to access quick settings.
2. Look for the airplane icon and tap it to turn on airplane mode.
3. For other devices, check the settings menu for the airplane mode option.
4. Some devices have a physical switch to activate airplane mode.

What your device can do while in airplane mode

Don’t let airplane mode hinder you from using your phone. There are many functions it can perform, especially if connected to Wi-Fi. Many airlines provide onboard internet access, and passengers can use their personal devices to access it, even while in airplane mode. Once in airplane mode, you can safely use any feature on your phone that doesn’t involve cell service.

Features you can use while in airplane mode:

What can’t your device do in airplane mode?

While airplane mode offers several benefits during flights, it also imposes limitations on your device's functionality as all cellular data is off.

Here's what your device can't do when in airplane mode:

• Make or receive calls (unless connected to Wi-Fi)
• Send or receive text messages (unless connected to Wi-Fi)
• Access mobile data
• Browse the internet (unless connected to Wi-Fi)
• Use location services
• Receive real-time alerts (unless connected to Wi-Fi)

Benefits of using airplane mode

Activating airplane mode on your device offers several advantages beyond just complying with aviation regulations. Remember, while airplane mode restricts some of your device's communication features, it also helps conserve battery life. You can even use airplane mode when on land to help conserve your battery when running low.

Here are a few key benefits you can enjoy when you switch to this handy feature:

• Decrease distractions during flight for you and fellow passengers
• Reduce data roaming charges (a lifesaver when traveling internationally)
• Faster device charging
• Extend battery life

How to prepare your devices for flight mode:

You can still enjoy many offline features and pre-downloaded content during your flight, including music, movies, shows, audiobooks, and more. Before your flight, while you have a strong internet connection, take a few minutes to download some content directly to your phone.

• Download entertainment: before your flight, download movies, music, or e-books for offline use.
• Charge your device: ensure your battery is fully charged, as you might not have access to power.
• Pack a portable charger: bring a power bank for extended battery life during long flights.
• Disconnect: turn on your out-of-office auto-reply.

FAQs

Can you listen to music in airplane mode?

Yes, you can listen to music that is locally stored and downloaded on your phone while it is in airplane mode. If you are connected to the plane’s Wi-Fi network, you can stream music. Airplane mode doesn't affect your ability to enjoy your favorite tunes during a flight; just download ahead of time and be prepared.

Can you receive texts in airplane mode?

You can only receive texts in airplane mode if your device is connected to the plane’s Wi-Fi network. Otherwise, airplane mode turns off all cellular connectivity. But don’t worry, you won’t miss a text; they will pop up as soon as you turn your phone or device off airplane mode.

Will I get charged if my phone is not in airplane mode?

No, there is no real way for flight attendants to know who has their phones in or off airplane mode. It is by the honor system, and it is for everyone’s safety. You may get charged roaming fees if flying internationally.

Does airplane mode help conserve phone battery?

Yes, airplane mode significantly helps conserve the phone’s battery and offers faster charging capabilities. Airplane mode turns off power-hungry radios and prevents constant searching for signals at high altitudes. It also reduces battery drain from apps requiring internet connectivity.

So, the next time you fly, turn your devices on airplane mode. Airplane mode isn't just a regulatory requirement; it's a simple way to contribute to a safer flying experience for everyone on board. Embrace airplane mode as an opportunity to disconnect from the digital world and escape. Whether you choose to relax, read a book, or watch a movie, you'll be doing so while prioritizing safety in the skies.
