Have you ever noticed tiny holes in the airplane window? Or why are we asked to close the window blinds while we are up in the air? Why do we open the window shades during takeoff and landing? I know all these questions made you perplexed, but why didn't you give a thought to them earlier?
We never bother as to why these rules have been imposed but, believe me, the answers to them are too significant and scientific. This post is to answer you, as to why the airline seats have to be in an upright position during takeoff?
Have a read to the interesting intelligence behind it.
This is the way a plane takes off, when all the seats become still in the upright position.
Takeoff and landing are two potential times when the plane may face technical problems. Thus, to keep the injuries to a minimum extent (if any) the seats have to be in an upright position.
'When the seat is up, it is locked. When the seat is back, it is not locked. In case of emergency, an unlocked seat has more force during impact and thrusting forward of that seat can cause passenger an injury', as told by Brian Manning; a flight attendant for Mesa Airlines.
In case of an emergency, the upright position clears the maximum amount of space for room to exit so that there is no mess created and the passengers exit safely.
All the seats are tested for very specific set of conditions including seat up and also the seat in the upright position. The seats pass or fail on the basis of how much bodily damage they do. If they are not in the desired upright position, the probability of surviving a crash situation becomes less, automatically.
The science is perfectly explained in this picture. When the plane is in an upright position, the weight of the body goes into the lower back as shown on the left-hand side of the image. This is important for the people suffering from sciatic pain and back injuries. Their backs have the best recline when the seat is in the upright position.
..takeoff and landing account for being the 'prime-times' of seeing accidents, the seats have to be in upright position because people sitting behind a seat that is unlocked or reclined will not be able to 'brace' properly. And bracing is necessary. Thus, there is no assurance of safety when the seat is in some other position, it is best to follow these rules and have a happy and safe journey.
