Passengers on airliners do not have parachutes...why?

a reply to: stumason

Those are called taxis not planes, because they'd never get airborne.

a reply to: Catacomb

Seriously, you're asking why the airlines don't provide parachutes for the passengers?

Uh, that would inspire real confidence of safety - NOT! The airlines would all be bankrupt.

Just wow.

Hmmm
ok jump out of a plane at 500 MPH and expect to live..
Oh and at 35000 feet... NO OXYGEN

People that drive cars are not by law required to wear 'crash helmets'; why?

Do airbags and safety measures taken for your car scare you? I think not... Do stairs with rails cause you to quiver with concern when you ascend, or descend? I think not...you get the picture.

Does the fact that 2 BILLION passengers flew on just 15 airlines (there are several hundred airlines around the world), and fewer than 300 died mean that we need to retrofit all aircraft to make them out or black box material? Or give passengers parachutes? I'm sorry, but 29 flight related accidents is nothing. There are more than 265 people killed in car crashes around the world in a day.

I'm basing this on absolutely nothing, but I would imagine most fatal airplane crashes happen pretty suddenly. If a pilot has time to bring an aircraft to a lower altitude and throttle back to a slower speed and wait until everyone has jumped he would probably have enough time to safely land the airplane somewhere instead.

During a decompression, you don't die or go unconscious instantly, but the more you move around the faster you lose consciousness. By the time you struggle into a parachute, especially if you aren't familiar with how to put it on, struggle to a door, and get ready to jump, you're going to be on the very edge of consciousness, if not out cold already. Most people aren't going to last longer than three or four minutes max. Even with specialized training the average person isn't going to last longer than 5-7 minutes before going out.

With all the panic that would be on the plane, most people wouldn't get out, or even get close to getting out. And that's if you were flying straight and level, and not diving down towards the ground, or losing control of the aircraft.

yes, it takes minutes to get out when the dam plane is on the ground!

imagine a panic at 30,000 ft!

hell, i'm not a big guy but even i have trouble moving around the plane with my back pack.

where the hell are people gonna put them on?

maybe make everyone wear one of them flying/gliding suits?

still need a chute, tho.

The panic is reduced to nearly nothing in the case of what one poster already said: an entire integrated emergency procedure that jettisons the top of the plane, and then ejects all passengers. No one has to panic, as the system detects catastrophic failures. Hell, all you would even need would be a triple fail-safe sensor for cabin pressure on each seat.

on paper it sounds great.

i'm guess that most of the time, the aircraft isn't polite in warning it will be fragmenting.
i go stir crazy after 1 movie.

will the bathrooms be ejected also? cockpit? galley?

maybe in spaceships where weight is not a problem, that would be a plausible idea.

a reply to: buddah6

don't forget that wind chill and air temp.

on the last flight i was on, the air temp at altitude was -59F.

people would be corpscicles when they hit the ground.

a reply to: Kr0nZ

You're exactly right. United 585, and USAir 427 both were on final approach, when they suddenly rolled over and dove into the ground. USAir 427 recorded three thumps on the CVR at 7:02:57. At 7:03:25 it slammed into the ground 80 degrees nose low, in a 60 degree bank, and over 300 mph. Even if there was an ejection system it wouldn't have saved anyone.

2 words!

FORCE FIELDS!

or a few of these;

the obvious answer to this is to throw the list of : air disaters at " parachute advocates

and ask the simple question - how many of thpse would have saved passanger lives with parachutes ?

Would major airlines allow one to board (say an extra extravagance beyond just the overhead baggage) wearing a parachute, or helmet? Would this frighten passengers? Even if blown out of sky or say a problem, you made your way after decompression to an exit door and made it. My thoughts about 911, and those folks that worked on the top floors of the World Trade Center was this: why didn't they have a reasonable escape plan. At that altitude I would have learned how to paraglide, and had a means to get though those windows with at least a parachute. As far as cars go, its your own choice (safely first to wear a helmet or not). Its up to you to design your own fate. If I was working on the floor of a building that was 82 stories in the air, I would have done some sky diving and had a parachute under my desk.

And I understand cabin pressure could be an issue, but couldn't a pilot drop the plane to a lower height and slower speed to make it possible?

In the case of MH-17 the plane disintegrated at altitude, parachutes would have made no difference.

Then engineer a solution instead of using 100 year old technology that states, "oopsie, in the case of depressurization, you are all dead."

How about every seat acts as an ejection seat, in the case of a catastrophic failure of the plane? Oh wait...I forgot...that would cost money to R&D, and implement.

Plus the weight of the seat would make the aircraft so heavy it would not get of the ground, the seat would have to be strong enough to punch its way through the overhead lockers, the skin of the aircraft, wiring, etc?

I have been wondering why passenger jets have not been fitted with any kind of cameras?
A camera pointing from each direction of the plane, camera pointing back onto the pilots etc.

Since 9/11 we have cameras everywhere.

Anyone?

How many car crashes are there compared to airline crashes?


Have you ever parachuted out of a plane?

And the next logical step is to ask; how do you get people to safely parachute out of a commercial aircraft?

Ejector seats of coarse that can put how many g forces on the human on ejecting?

Zaphod?

I think you mentioned in another thread that it could be up to 20-30 g's for a split second?

Yeah the fit might survive, how healthy and fit is your average person today?

My opinion is not very and whats suggested by OP would kill more than it would save in case of an emergency.

They could just equip the plane with these. Larger aircraft get more of course.
