What is the point of putting life jackets on planes,surely a parachute would be more useful?
Answers:
In a controlled "ditching over water" where you might be able to use a chute if you had enough altitude. you can also survive the trip to the water staying in the plane. Then the obstacle is staying afloat since the plane will soon disappear. Most people know how to use a life jacket. Not many know how to skydive. and even parachuting, you would still be out of luck once you reached the water if you didn't have a life jacket. And there is the issue of having people scattered over miles of ocean.
In an out-of-control "crash" a chute or a life-jacket would be useless since you can't jump out of an unstable speeding plane.
The manufacturers of Cirrus aircraft have added parachutes to the airplane. ;-)
Aloha
Not if you crash into the sea!
Ref: Other comments about crashing into the sea,
It is entirely possible - this guy managed it ok! ;o)
(actually, you're quite right - I would imagine landing on the sea and remaining in one piece would be highly unlikely. actually. about as unlikely as crashing an aeroplane at all.. but just in case. I'd rather have a life jacket all the same!!)
so.. in conclusion, it's clearly a bit of a placebo. !
I've always wondered that too. If you crash into the ocean a life jacket is not going to help what's left of you.
Even if...and that's a big if..you do survive a water crash do they really think you're going to put a life-jacket on before you try to find your way out of a sinking plane?
Ridiculous!
I suppose it's some sort of regulation that the airline industry wants. Makes them feel better, but doesn't do a damn thing for passengers.
if you ditch in the sea then you would need a life jacket.
The life jackets are for crash landings in the sea, if you crash land anywhere else you may as well kiss yourself goodbye, by the time a whole flight put on parachutes the plane would have blown up 4 times.
not if you crash into the sea
If you jumped out of a commercial plane wearing a parachute.wouldn't the engines suck you in when you jumped?
You have a better chance of landing in water and using a life
jacket to float then trying to get a bunch of people to jump out
of a plane. Imagine trying to get 200 people, including old ladies
and children and overweight ones to jump out of a jet traveling
at 500 miles per hour...
What would you do with a parachute in the sea. Besides If a plane is going down by opening the emergency doors so you could jump would depressurise NOT a good Idea.
it takes alot of training to use a parchute correctly. if u crashed on the water a liftyjacket would do a lot of more good then a parachure
pilots will try their best to land in a safe spot.. however.. in an emergency situation, where no land is safe to land, water is the best resort.. and when you land in the sea/lake/river etc. u do need a life jacket to prevent you from drowning and the light on the life jacket will make you visible to rescue teams..
It's a federal regulation to have them. Also as others have stated a parachute jump is not as simple as it looks. The altitude must not be too low to open or too high without oxygen breathe. The speed must be slow. The aircraft has to be depressurized. You have to clear the plane without a wing or engine hitting you. Then there the weight & bulk of parachutes and the lack of training on falling.
WAY too expensive! Also, there's the situation where it might not open, there's a lawsuit. Also, there could be a wack-a-doo on the plane that decides to take all the chutes for himself or steal them off another person. PLus, chutes are expensive on the market. They could easily be stolen and ther's lots of money loss for the airlines.
Lets be honest.
If you are in a plane & it crashes you are quite surely scr*w*d. The airline give you a lifejacket to put on to give you something to take your mind off the fact that you are going to die. And besides, a parachute each would take up too much room.
There are some good answers on this question, however one of the mainreasons is that if a plane crashes at sea there are very few things that will float on a plane after the first hour. apart from LIFEJACKETS !! They are bright Yellow so they can be seen by search and rescue.
Grab a parachute by all means but if you bail out over the ocean, good luck getting the chute off once you hit the water !
i think that if your in aeroplane crash then it is highly unlikely that you would survive but life jackets are brightly coloured so it would help you be seen, also parachutes are bulky and you need training to use them (tricky in a plane that's about to crash?)
