imagine what would have happened if your stow tray table is down, and the plane does a emergency stop? your momentum will bring you forward, and *ouch*...worse still, if there's a cup of hot coffee on the table.
seat upright: same reason, but to protect the person behind you?
open windows: to enable visibility of the plane at night? since it's a standard procedure, so air stewards follow it even in daytime?
disclaimer: i'm not from the airline industry, just giving my 2¢
If anything were to happen, you tink still have time to look thru the window?
maybe everything will be everywhere already.... if u still dunno where to evac then I think you must be dead already.:dunno:
The reasoning is that you need to be able to rapidly and clearly assess the conditions outside during an evacuation.
The reasons the window shades must be up during take off and landing is so that in event of engine fire or smoke then passengers can alert the FAs who will in turn alert the pilots. As pilots cant see everything during the take off and sometimes nothing is indicated in the cockpit. Also, if part of the flaps tear or any other peculiar thing that may happen then passengers are the eyes. In the event of an evacuation having the window shades up also allow passengers to see the outside conditions and adjust accordingly, for eg. if there's a fire on that end then don't run to that exit but another.
true to our creed indeed :bsmilie:
gotta ask my pilot friends why the requirement, i've always found it irritating esp when you're the one next to the window and the sun's in your face.
all the speculation aside, its a human thing, same as why we have windows in MRT trains even though the NE line is all underground. ppl need to see what's going on, its a psychological thing. fights claustraphobia i guess...
