HOW DOES AN AEROPLANE GET ITS SIGNALS?:
Usually signals are sent to the aeroplane in the form of radio waves from the air traffic control stations in the ground, to navigate the aeroplane where it is present in the sky. To avoid air crashes and false landing crashes.
AEROPLANE MODE:
Our electronic devices like mobile phones, tabs, laptops uses radio waves to call or to convey a message to someone. While we are travelling in flight we are supposed to turn on flight mode or Aeroplane mode which usually stops all the radio waves emitted by the devices to avoid interaction with radio waves sent by the ground stations. When we switch ON aeroplane mode we can't call or even text to someone either through messenger or other message conveying apps like WhatsApp, etc. But we can use Wi-Fi to browse something. The aeroplane mode was first introduced by Qualcomm in the year 2000. Which allow us to use mobile phones in the aeroplane without actually switching it off.
