Airplane Mode is a common feature found in almost all smartphones today. It is commonly used to quickly stop cellular and social media notifications to promote focus on other tasks. Despite being similar to the ‘Do Not Disturb’ mode present in smartphones, Airplane Mode serves a specific purpose related to air travel. But why is it essential? Can a smartphone really disrupt an entire aircraft if Airplane Mode is not activated?
To answer these questions, we need to delve into the past when the US Federal Communication Commission (FCC) prohibited phone calls on planes in 1991, a regulation that was later adopted globally. This ban was put in place as radio waves emitted from phones could potentially interfere with critical aircraft transmissions, such as communication between air traffic control and pilots. This was crucial to ensure safe navigation and communication, especially during tasks like avoiding storms or mountainous terrains.
The concern regarding interference also extended to audio and video players being considered a risk to aircraft avionics. However, with advancements in avionics technology, planes are now equipped to resist such interference from phones. Consequently, the restrictions on smartphone use during flights were eased in 2013, allowing passengers to use their devices without causing disruptions.
While traditional devices like iPads can be used to watch locally-stored content during flights, streaming movies or playing online games on a plane is considered risky. Hence, the introduction of Airplane Mode, which blocks all radio transmissions from a phone while still enabling safe device use during air travel.
One limitation of Airplane Mode is the inability to access social media via cellular networks during flights. However, many airlines offer in-flight WiFi services for passengers to stay connected. It’s important to note that voice calls are still restricted during flights and only permitted in exceptional circumstances.
In conclusion, activating Airplane Mode before air travel is essential to prevent potential transmission issues and ensure a seamless flight experience.
