Electronic equipment with an aerial must be turned off from the moment you board the plane and during the flight. Electronic equipment without an aerial, such as CD/DVD/MP3 players, laptops or electronic games can be used during the flight and when the aircraft is on the ground. As soon as the ‘fasten your seatbelt’ sign comes on (during take-off and landing and sometimes during the flight), all your electronic equipment must be turned off and put away.
