Travellers on Qantas and Virgin will be able to keep their electronic devices powered on during all phases of flight from Tuesday.

The Civil Aviation Safety Authority on Monday approved applications from both airlines that will allow passengers to keep their phones, tablets and e-readers on even during take-off or landing.

The devices will need to remain in "flight mode" throughout the flight.

Devices weighing more than 1 kilogram, such as laptops, will still need to be stored for take off and landing. Smaller devices will need to be held by a passenger or secured in the pocket of a garment or the magazine pocket on the back of the seat.
