Obviously people wouldn't be jumping out at max height. The plane is falling... therefore you're likely to be several thousand feet lower by the time you even know to get out.


Easy there Charlie's Angels. I think you've watched too many actions movies and smoked too many bowls.

Is this a serious thread? Are you serious?

The lowest bidder...

Makes the aeroplane
Supplies the fuel
Parachutes weigh a lot
Use more fuel

At some point, someone in the industry figured that at the rate aeroplanes don't fall out of the sky, that they can save millions of dollars every year in profits by not caring if you and a few hundred people ditch into the dirt without a parachute.

Your airfares are cheap for a reason

but that "tiny" chance isn't big enough to justify all the modifications it would take to make planes jumpable, and even then its probably even smaller than "tiny".

for instance, where is my parachute located?

leg room > parachute.



Not to mention the horrible technical challenges, lets see...

How many parachutes are actually functioning and stay functional flight after flight.

How do you design a one size fits all harness that can fit an infant to a full size adult, not only a full size but overweight individuals.

Make a reliable altimeter system to deploy the chutes and also make sure the chutes can deploy at lower altitudes.

As you can see by this graph from http://www.planecrashinfo.com/cause.htm most accidents and fatalities occur in either the beginning or ending phases of a flight when altitude is actually quite a bit lower than cruising altitude.



Most actually occur either on take off or just after or right before landing or as the plane has landed. Parachutes would be useless in these situations unless every airline seat was a zero-zero ejection seat capable of safely lifting the passanger up and away from the aircraft using small rockets (these are the same type of ejection seats in fighter aircraft).

Why? Because I don't know whether planes depressurize during a crash? *confused*

LOL! Yes Bas, I was serious.

When people are thinking about things, it's sometimes hard to think of all the ways your idea is stupid and wouldn't work. I come to TA to have people help me out

I know they love to do it... and I am a people pleaser, so here I am!

G Force

Basically, most people wouldn't be able to walk in a falling airplane. There's also the fact that the fall itself would knock you unconscious so it's not like people are screaming and flailing their hands to the very end.

How many G's would you get when jumping out of a plane going that fast?

Humans can sustain upwards of 9 G's for brief periods of time. If you deployed a parachute, you wouldn't have as many G's as you initially did when jumping out.

With that being said, if you were to stay in the plane and go down with it, would you likely be passed out long before you even hit the ground?

Anyway, I get that it's a dumb idea, just discussing now.

What is wrong with you? What kind of asinine questions is "why don't people have parachutes when they fly". Jesus.

This thread gives me a headache.

Most all of your assumptions are wrong, and every one of your wild hypotheticals is a...wild...hypothetical.

Uh... Technically in free fall you have 0 gravities I think...

Also, read my posts I already said you'd pass out, thats why they have the masks.

LOL you're ridiclous. It's not that asinine, nor is it that obvious to people when they don't know the logistics of parachuting or plane crashes for that matter.

Get over yourself and go find your boyfriend or something

P.S. infinity HiGH you edited your post after I made mine... damnit!

Have you ever been on a roller coaster? Imagine how hard it would be to get up and walk around on a roller coaster. That's close to what a plane crash is like. Once the plane is falling you're fucked. You don't just get up with your parachute and hop on over to the exit. Combine that with 100+ other people who would be attempting this same feat and you have no survivors either way. But you blew a shitload of cash on parachutes, lol.

edit: you need to watch Discovery during the day. They have this one show that talks about plane crashes and what went wrong, bla bla bla. Not once did this idea cross my mind while watching. Too much chaos for something like this to even be suggested.

Mine?

I asked a question. I claimed ignorance and made no assumptions. Just wanted to have a discussion.

Good lord you people are touchy. Just have an interesting conversation and stop flipping out about shit. Take some midol!

Correct me if I am wrong, but aren't the emergency exit doors behind the engines? Therefore pushing you away and not sucking you in?

Infinity, there have been crashes where the pilot knew there was a problem before the plane lost control.

Yes, odds are very low that you would survive or that conditions would work for it... but it seems like you would have at least a teeny tiny percentage more of a chance of survival than just sitting there waiting to crash.

EDIT: The emergency exit doors in the middle of the plane is what I am referencing, not the ones in the front.

Yeah, those doors are designed to be used after an emergency landing. Or did you think the automatically inflating slide is just a fun way to launch yourself off the plane with the parachute?

Its not that you claimed ignorance, its that you are actually ignorant of it in the first place. You obviously did not make any sort of rational personal thought of the question before you made this thread.

Its just electrons and some magnetic bits on a hard drive some place but this could probably be construed as an actual waste of matter. You know the stuff that theoretically is never lost, just transmuted and shifted around... Yea you actually broke the laws of physics and the universe by making this thread.

It really was that stupid.

I don't have TV... but I might youtube it if it's on there.

So more on the idea of a parachute on the entire plane. Wouldn't the parachute have to be monstrously large? AKA VERY heavy?

Krypton if you were being serious, how would you suspect that would work?


Posted by Clovis on Jul-14-2009 06:55:

Suffice to say, if this was a good idea, it would already have been done for years. It is not a viable, logical idea for a number of reasons, most of which have been pointed out and most of which are quite ridiculously obvious if you just think about it for more than 10 seconds.

Flying is the safest form of mass transport of all time anyway and the net gain in survivability of crashes from having parachutes on all aircraft if it were even feasible in the first place would be an incredibly small fraction.

Not to mention that most crashes happen at altitude where fucking parachutes would be worthless, except in the hands of expert skydivers, as in less than 5000 feet.

Or, I was reading an article about a plane crashing and I thought "hmmm, why couldn't they have parachutes?" and thought maybe it would spark a somewhat intelligent conversation on TA. I should have suspected that I would get flamed for it, but ah wells.

Maybe I should just start posting about my boyfriend and how I like to masturbate so I can win the affections of all of you back?

They already have parachutes for certain light aircraft which have proved to be of little use in practice.

The logistics and variables involved in trying to make them work for large passenger planes are so huge that any possible gain is not worth it, thus why this has never been done and likely never will.

At least that would be less angering and I would be able to ignore it more easily.

Or you could post something intelligent?


Posted by Clovis on Jul-14-2009 06:59:

If we really wanted to prevent more plane crashes we would train and pay pilots better because that is the biggest culprit as far as aviation safety goes in my opinion.

Airplanes are safer than ever yet they are still crashing at the hands of complete idiots flying them or over stressed, over worked, and under paid professionals.

Why bother? It either gets ignored or a bunch of people who love to hate me jump all over it and find any minute detail to bitch/complain/insult/criticize about.

Let the hate train continue on...

((((((((((((HUGS)))))))))))))



*shoves you off the train*
