In a plane.?

Question

smoking is not allowed because it can cause a fire..

by why are cellphones and laptops also not allowed? whats wrong with them what can they cause?

Answer 1

they can be used once you are underway

Answer 2

Laptops are allowed to be used. I use it all the time to do work, that is why many airlines offer power ports for you to plug in your laptop so that it has power. Cellphones on the other hand are not allowed because when they are turn on, they can interfere with the navigation system.

Answer 3

As I know cell phones emit strong radio signals that could cause false readouts on an airplane's navigational equipment, in addition to this Laptops and mobile phones give off electromagnetic radiation which can cause electrical currents to flow in the aircraft systems circuitry to bad effect, this is why airlines tell people to switch these things off during the flight.

Answer 4

when you're taking off and landing, their signals can interfere with the pilot's radios, causing him to lose contact with the air traffic controller. this can be extremely dangerous
