Why is it not allowed to talk on the phone on a plane?

Question

On every flight they tell you to turn off your cell phone. Why?

Answer 1

When a plane is taking of, flying, or landing they can't see everything - most of what they're doing is actually from someone behind a desk telling them where to go. (this is why they have those 'goofy' looking headphones) And when you receive or send a textt, voice mail, and/or a call it causes an interruption. If it's only one or two phones they can handle the interruption, but if there are too many interruptions it can cause an accident.

Answer 2

They also tell you in their information kit why cellphones(and other electronic equipment) must be turned off at time of take-off and landing, and other times during the flight.

The reason is that radio waves from these gadgets can interfere with the radio system of the airplane.

Answer 3

Because it interferes with the navigation and communication systems.

Answer 4

The signal from your cell will interfere with electronics and navigation devices.  For example, a cell phone can dis-engage the auto pilot on the MD-80.

Answer 5

It disturbs the planes electrical stuff.
