Safety Behind Flight Mode

Flight safety is behind the flight mode rule. While today's networks may not pose a huge risk, even a small signal is crucial during takeoff and landing. After enabling airplane mode, only Bluetooth and Wi-Fi work; the mobile network is blocked.

What's the problem with flight mode?

Aviation experts say one phone with its signal on won't cause much harm. But if everyone's phone is connected, it can affect the aircraft's communication system, causing issues during takeoff and landing.

Network Connection

If flight mode isn't on, your phone will search for networks, relying on ground towers. If all phones do this, it can impact the aircraft's connection, potentially affecting its navigation and control systems.
