Some passengers won’t turn off their mobile phones or iPads during takeoff or landing. It happens on almost every          now. It’s time to turn off personal electronic devices when the plane’s door         . However, there’s always at least one person who keeps talking, texting, playing, watching or emailing — and          strict orders to power down during flights.
“People have become so          to those devices, and a lot of people          whether they really need to turn them off,” says an airhostess from Southwest Airlines.
Is turning off the devices really          in the first place? Lots of passengers have doubted about the          of leaving devices on. They think one cell or message or game isn’t going to          down the plane.
Indeed, there’s no          scientific evidence that having devices powered on during takeoff and landing would cause a         , only that there is the potential of a problem.
In the US, pilots are allowed to use certain electronic devices during takeoff and landing, but if passengers’        devices are tested at the same time, it may lead to wrong warnings and          readings on the aircraft instruments. In some studies researchers found mobile phones could          global-positioning satellite systems or other aircraft systems. Though the effects are          slight, they could result in disaster.
If even the          possibility of disaster exists, it’s better to turn them off during takeoff and landing.
