• Why shutter window lift during takeoff and landing
From the point of view of passenger request to lift the window curtain at takeoff is absurd: how it will help the plane fly? However, the rules have their own, quite earthly justification.
The crew wants you to raise the curtain not only during takeoff, but landing. Here, some believe that this is done to ensure that passengers can enjoy the view from the window. Not even close: raise the shutter need in case of an emergency.
It is estimated that during emergencies in flight attendants is about 90 seconds to lift people out of the plane. Open blinds allow people from the special services of emergency in time to see what is happening and to help.
In addition, open the shutter will make it possible to navigate in space and by passengers. Light quenched too, not just this: it is done to your eyes become accustomed to the dim lighting - in the crash you hardly someone to light a lamp.
