Must've often boarded the plane, right?
But surely most people do not know the reason why take off time is the same landing, stewardess always ask for tegakin chair back, tray table it must be closed, window cover must be opened, keep sitting in row door should be free from all bag etc?
So, the reason is because 90% of plane crashes occur during take off and landing.
Plane Take Off and Landing
90% plane crash occurred in 8 minutes after take-off and 3 minutes before landing.
So called "Critical Eleven"
And when that happens, passengers only have time * 90 seconds * make out of the plane.
If you do not get out, passengers can die because of various things, from smoke inhalation or oxygen deficiency, or incase of ditching (water landing) sinking planes.
One emergency exit in cabin, designed to evacuate about 65 people within 1.5 minutes. Tegakin backrest especially when panicked, can discharged time 10 seconds, and while evacuation 1 second was already a problem of life and death.
Get used to reprimand if passengers in front of us do not hold the back of his chair, because when there is an emergency landing, which will be affected is the person sitting behind him.
Karna will trapped (trapped) and ga can get out of the chair .... while the passenger in front of it would run out as fast as possible in order to survive.
Not only that, in the evening flight, cabin lights also must be dimmed? The reason is the same, because within 90 seconds all passengers must be out then there is no time to waste.
When the eyes accustomed to see the light and the lights off, it would take some time for the eyes to adapt to the dark lighting ... then from that light deliberately dimmed so that the eyes do not need adaptation again when there is an emergency landing.
If the cabin window cover must be opened that why?
In training pilots and flight attendants there is a class who called "CRMC", so the class about communication.
Because 70% more aircraft accidents occur because of lack of communication between everyone, ie between flight attendants, pilots and passengers.
In flight we have to use all existing info, including dr passenger.
Glass is opened so that passengers can clay outside.
For example there is a fire on the wing, captain ga can be tough, stewardess ga gaat. maybe even the passenger who clay and can love info so that can be as soon as possible evacuation
Or if in European countries, sometimes the wings of frozen planes because of ice, passengers can see and love info so the captain knows and we can make repairs before flying.
The following Safety Equipment Inside the Aircraft
Seatbelt
Life jacket
Oxygen mask
Emergency door
Streetlight in the cabin
So in conclusion, listen to mbak pramugarinya .. because if there is accident, who will get the consequence is the passenger itself.
So do not play with safety
