What's the difference between "below 10,000 ft" and "during actual take-off and landing roll?" which per the text is the new rule?
Also, it says "put away books and magazines," does that mean print ones as well? And the graphic says "put away heavy devices" but the text doesn't mention this. How much does a heavy device weigh?
This is all so vague, it's worse than the old rules.
The reason for devices being stowed during take-off and landing roll is not because of their electronic danger but because they can become a physical danger in the cabin and become airborne and possibly injure someone. Printed material would be included in this.
