How can an electronic device which does not transmit a signal interfere with the operation of the airliner? Obviously pacemakers, hearing aids, and wristwatches aren’t turned off.
Electronic devices interfere with the signals being received by the airplane while its flying. So, batteries are also not allowed in any airlines because they interfere with the radio signals being received by the crew in the cockpit of the airplane. So, its always advisable to turn them off before flying. But, you can use a laptop or an IPOD after a certain time interval on the airplane. But, listen carefully to all the announcements being made by the airhostesses on electronic gadgets and if you feel, you can ask them the same question for the perfect answer if you’re not satisfied with my answer. Goodluck!
