>>211684340Airplane mode is required during flights primarily to prevent potential interference with an aircraftโs communication and navigation systems, which rely on sensitive radio signals. Although the risk is low with modern aircraft, aviation authorities enforce this precaution as part of international safety regulations. Mobile devices, especially when not in airplane mode, emit radio frequencies through cellular, Wi-Fi, and Bluetooth connections, which could disrupt cockpit instruments or air traffic communication. Additionally, at high altitudes and speeds, phones struggle to maintain stable connections by rapidly switching between cell towers, which can disrupt ground networks and drain device batteries. Enabling airplane mode ensures both onboard safety and network stability, while still allowing for controlled use of Wi-Fi or Bluetooth when permitted during the flight.
