I do think so. I mean it's not necessary to. It's pretty unusual.
during takeoff and landing
The flaps help to increase lift, which is essential to the landing and takeoff phase[s].
The flaps, when extended, basically make the wing bigger which generates more lift. during takeoff, it helps to have as much lift as possible to aid the aircraft in it's ascent into the air. during taxiing, there is no real benefit to having the flaps out. the reason the flaps are extended during taxiing is to save time. if the flaps are extended while the plane is taxiing, it doesent have to do it later before it takes off.
Safety belts during takeoff and landing and while en route; shoulder harnesses during takeoff and landing.
Yes, as long it is not on during takeoff.
Yes, they will just ask you to turn them off during takeoff and landing
Yes, with ear buds. You cannot play it during takeoff or landing, but in flight is OK.
Only during landing and takeoff. Cell phones interfere with their radio communication. The phones are really the problems but don't use any technology on landing or takeoff because the flight attendants will give you a dirty look and ask you to turn it off
You might get receive an order to "Hold short of runway" before takeoff, but not during takeoff. That just means that the tower wants you to remain on the taxiway because another aircraft is taking off or landing and hasn't yet cleared the runway. Once you're "cleared for takeoff" you can taxi onto the runway and takeoff
So that the reclined seat back will not interfere with the evacuation of the aircraft in the event it becomes necessary
Yes,you can but sometimes they wont allow it but most of the time they do warning:you cannot play during takeoff or landing and do not have any internet swithes on
yeah there are lot of procedures, checklists and other stuff that the pilot or te copilot make while the pilot or the copilot flies the plane during the landing or during takeoff
