(CNN) — “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.” We know the drill. But how much of it is indeed truly necessary?
Most of those rules make perfect sense. Upright seats and stowed tray tables ensure fast exits in emergencies. laptops, if not secured, could become dangerous projectiles. But what about airplane mode? Is it a relic of the past, or is there a real risk to using your phone on a plane?
The History of Flight Mode
aviation relies on radio communication, a system carefully coordinated as the 1920s to minimize interference. Modern digital technology is far more advanced than the analog systems of the past.However, research has indicated that personal electronic devices can emit signals within the same frequency bands as an aircraft’s communication and navigation systems, potentially causing electromagnetic interference.
Though, back in 1992, The US Federal Aviation Authority and Boeing conducted an independent study and found no issues with computers or other personal electronic devices during non-critical phases of flight. (Takeoffs and landings are considered critical phases.)
The US Federal Communications Commission also created reserved frequency bandwidths for different uses – such as mobile phones and aircraft navigation and communications – so they do not interfere with one another. In the EU, electronic devices have been allowed to stay on since 2014.
The real Reason for Airplane Mode: Ground Interference
So, if international standards are in place, why the continued ban on mobile phone use? The answer lies, surprisingly, on the ground.
Wireless networks are supported by a network of towers, which could become overloaded if all passengers flying over these networks used their phones at once.The number of passengers who flew in 2021 was over 2.2 billion, and that’s half of what the 2019 passenger numbers were.
The 5G Factor
The emergence of 5G networks has added another layer of complexity.These networks, while offering faster data speeds, operate on bandwidth spectrums remarkably close to those used by aviation. This proximity raises concerns about potential interference with navigation systems, especially during landings near airports.

The Verdict
while the risk of your phone directly interfering with a plane’s navigation system may be low, the primary concern revolves around potential ground network overload and, more recently, 5G interference with sensitive landing equipment. So, while the rules might feel outdated, they are still in place.
Why is enabling airplane mode on a flight critically important, even with in-flight Wi-Fi?
Airplane Mode on Flights: Why It Matters & How to Use It
The Importance of Airplane Mode: Safety and Regulations
When you board a commercial flight, the flight attendants will almost always announce the importance of putting your electronic devices into airplane mode or turning them off entirely. But why this seemingly simple request? The reason boils down to flight safety and preventing potential interference with essential aircraft systems. Specifically, the focus is on the potential for radio frequency interference (RFI) from cellular devices, which must not disrupt the very sophisticated and sensitive equipment designed to ensure passenger safety.
Understanding Radio Frequency Interference (RFI)
Your smartphone, tablet, and other electronic devices emit radio waves to communicate with cell towers.These same frequencies are very close to those used to communicate with air traffic control, navigate the aircraft, and manage other important functions. The primary concern is that these signals could interfere with the aircraft’s electronics.
- Navigation Systems: Interference could disrupt signals from the satellite navigation system, leading to inaccurate position reporting and possibly affecting the aircraft’s ability to stay on course.
- Dialog Systems: Interference might interrupt communications between the pilots and air traffic control, posing a significant risk during critical phases of flight (takeoff, landing, and emergencies).
- Electronic Displays: Glitchy screens and other distortions could lead to misinterpreted details.
While there are no confirmed cases of an incident directly caused by passenger devices impacting the aircraft’s controls [citation needed], the potential for safety issues is real. Modern aircraft are built with shielding to minimize these risks, but the regulations are in place as a preventative measure.
How Airplane Mode Works: Disconnecting and Connecting
Airplane mode disables your device’s ability to transmit and receive radio signals. In practical terms, it turns off:
- Cellular data and voice calls.
- Wi-Fi.
- Bluetooth.
- GPS.
By disabling these features, you minimize the risk of your device interfering with the plane’s systems.
What you Can Do on Airplane Mode: entertainment and productivity
Even with limitations, airplane mode allows for plenty of functionalities. You can still use your device for entertainment and productivity.
- Listen to downloaded music and podcasts.
- Watch downloaded movies or TV shows.
- Play downloaded games.
- Use pre-downloaded maps.
- Read eBooks.
- Work on documents or emails offline (for later sync if Wi-Fi becomes available)
Using Airplane Mode Effectively: Tips for a Smooth Flight
To fully embrace airplane mode while understanding device restrictions on flights, follow these practical tips:
- Enable Airplane Mode: Immediately upon boarding or as per flight attendant instructions. The setting is usually accessible through the quick settings panel on your smartphone or tablet.
- Wi-Fi and bluetooth Toggle: Most airlines allow you to enable Wi-Fi (if available) and/or Bluetooth after putting your device in airplane mode. Just be sure to turn these off again during takeoff and landing, or when specifically prompted.
- Charge Your Devices: Airplane mode conserves battery.Ensure your devices are fully charged before your flight to maximize thier usage.
- Download Content: before your flight, download movies, shows, podcasts, music, ebooks, and other content to enjoy offline.
- Consider a Power Bank: Especially for long flights, bring a portable charger to keep your devices powered up.
Airplane Mode vs. Turning Off: Understanding the Difference
While some flight attendants may still suggest turning your device off entirely, airplane mode is generally accepted as safe and compliant with flight regulations as it automatically shuts down all transmitting functions. Turning the device off will always accomplish the same result as airplane mode.
The Future of Connectivity on Flights
the prevalence of in-flight Wi-Fi is changing the way we think about airplane mode. Many airlines now offer Wi-Fi, often for a fee. With these services,passengers can connect to the internet and stay connected during their flights. although Wi-fi is becoming common, airplane mode must still be observed when not using it.
| Functionality and Airplane Mode | Status |
|---|---|
| Cellular data and voice calls | disabled |
| Wi-Fi | Can be enabled (if airline provides service) |
| Bluetooth | can be enabled |
| GPS | Disabled |
The goal is always to create a safe and enjoyable travel experience for everyone. Your compliance ensures that and that the aircraft operations run smoothly.
