When you board a plane, you are reminded to put your seat in an upright position, stow your tray table, raise your window shade, and switch your electronic devices to flight mode.
The reasons behind the first four instructions are clear: window shades allow for visibility in case of emergencies, tray tables and seats need to be stowed for quick evacuation, and laptops can pose a risk during emergencies.
But what about putting your mobile phone on flight mode? The answer is not as straightforward.
Airplane navigation and communication rely on radio services, which have been carefully coordinated to minimize interference since the 1920s.
The digital technology used in personal electronic devices emits signals within the same frequency band as the aircraft’s communication and navigation systems, which can cause electromagnetic interference.
However, a study conducted by the US Federal Aviation Authority and Boeing in 1992 found no issues with electronic devices during non-critical flight phases. Subsequently, reserved frequency bandwidths were created to prevent interference between mobile phones and aviation systems.
While airport operators in Australia and the US have raised concerns about 5G interference, the technology has been allowed on planes in the European Union since 2014. However, it is still advisable to limit mobile phone use during flights until these concerns are resolved.
Many airlines now offer Wi-Fi services on board, which allows passengers to use their phones for communication. However, excessive phone use during flights may disrupt cabin crew services and create social disturbances among passengers.
It is important to consider the overall passenger experience while discussing the use of phones in flight. Disruptive behaviors, such as noncompliance with safety requirements and altercations, have become increasingly common. Therefore, allowing phone use in-flight may contribute to a more disruptive environment.
In conclusion, using mobile phones in flight does not currently pose a risk to aircraft operation. However, considering the preferences of cabin crew and the potential for interference with aircraft navigation, it is still advisable to exercise caution and limit phone use during critical flight phases.
The use of phones during flights is a complex issue that requires further research and consideration. While it may be tempting to use phones for in-flight communication, it is important to prioritize safety and the overall well-being of passengers and crew.
