Airplane mode can be an attribute of mobile computers and devices which shuts all of the radio chips that might hinder an airplane's communication and navigation systems. After Airplane mode is turned on, Windows 10 simplifies the wi-fi system card, Bluetooth, and any mobile data connection (3G/4G/5G) that you might have. If your Windows 10 laptop or tablet has wireless projection capabilities, through technologies such as Miracast, they are also disabled by Airplane mode. You should turn on Airplane mode once you board planes. After take-off, then you are able to separately enable the the Bluetooth, in the event that you need to utilize them while on the plane. After Airplane mode is still active, Windows 10 displays an airplane icon like the one below, in the system tray.
