This depends on the type of aeroplane. In the case of a VTOL jet the speed is actually zero.
Yes, passengers are typically required to keep the airplane window shades open during takeoff and landing for safety reasons.
Airplane windows need to be open during takeoff and landing to allow passengers to see outside and help maintain orientation in case of an emergency evacuation.
The Vr (rotation for takeoff) speed of a Cessna 172 is around 55 kts. The final approach speed is around 60 kts. When landing pilots strive to stall the airplane at the same time that the wheels touch the ground this happens at around 50 kts.
The aeroplane takeoff is controlled by the engine speed and the elevators.
137knots as an average
They are useful for takeoff to get lift and at landing for slowing down the plane.
Airplane window shades have to be up during takeoff and landing for safety reasons. This allows passengers and crew to see outside in case of an emergency, such as a fire or evacuation. It also helps the crew assess the situation outside the aircraft.
Flaps and stats increase lift for takeoff and slow you down, for landing.
Yes, Flaps are both used to create lift (on takeoff) and to slow the aircraft (on Landing)
"V1" is the speed at which the flight crew must either continue with the takeoff or abort the takeoff. It is the last point at which aborting is an option.
Yes, electronics are permitted to be used on aircraft after reaching 10,000 feet after takeoff and before landing.
Yes, with ear buds. You cannot play it during takeoff or landing, but in flight is OK.
