Why there is no protective equipment to survive people on board during flight crash?

Question

Is it not possible to provide/wear parachute to each passengers on board which can activate either with high noise level or sudden change of atmospheric pressure?

Answer 1

Because a plane breaks up in flight every 100,000,000 flights, and a crash occurs about ever 3,000,000 flights, so it would cost over a billion and a half dollars ($100 parachute times 300 seats times 50,000 planes) to do that, and it would save about 1000 people every 60 years. And it would add considerable weight, which would increase fuel consumption, and cost a bundle over the long term.

Answer 2

Ive completed an army parachute course and witnessed first hand how many injuries can occur (ie brocken legs) after intentional parachute decents especially at night.

It is true that at cruising altitude of most modern airliners (36,000 feet) the temp is -56 degrees celcius.

Also alot of flights also travel over water.

So after considering the above i think id rather take my chances staying with the aircraft where atleast there are escape slides which convert into rafts if you happen to come down over water with an EPIRB and enough supplies to keep you alive for several days where resurers know exactly where you are to come and pick up the pieces. Instead of jumping out of (door #5) the rear door of a 747 with your parachute with another 400 passengers where if you survive the jump into -56 degree temperatures you still have to contend with landing possibly into trees or the ocean at night by youself with nothing but the cloths you boarded the plane with and with the aircraft comming down possibly hundreads of kms from your location and rescuers not knowing where the hell to start their search.

One last thing aswell im sure that it would be possible for an airline to start providing parachutes onboard but i tell you what it would be a safe bet i wouldnt be flying with them.

1. At altitude, you'd freeze to death instantly upon exiting the aircraft. The temp is typically -40F to -70F. At normal cruise of 500 - 650 MPH, every bone in your body would be shattered when you hit the slipstream; most people's arms and legs would be ripped off by flailing injuries. Think of all of the crushed and frozen arms, legs, and bodies with unopened parachutes attached hitting the ground at terminal velocity -- about 125 MPH.

2. Most accidents happen during the transition period of takeoff and landing. You're too close to the ground for parachutes to be effective and there isn't enough time to get everyone out anyway.

3. There are no doors on an airliner that can be opened in flight, so there is no way to get out anyway.

4. Parachutes need to be donned before getting on the airplane. You'd need to show up 5 hours before departure to get everyone suited up. Connections would be 5 - 7 hours.

5. The bulk of the parachutes would require the airlines to remove half of the seats to make room. Add the cost of parachute riggers and staff to help passengers put them on, and airfares would quadruple at least.

6. The typical airline passenger isn't trained in the use of a parachute; it would be akin to handing a 5-year-old a loaded AK-47.

Answer 4

It is not practicable to supply passengers with parachutes because:
1. to bail out at altitude you would have to decompress the aircraft and most passengers would be unconscious in seconds.
2. If you jettisoned a door after decompressing the cabin, you would not physically have the strength to combat the airflow and bail out.
3. If you managed to clear the door, you would hit the aircraft structure, or be sucked into the engines and be killed.
4. If you missed the aircraft, the airstream would tear off all your clothes and probably much of your skin at minus 50 degrees.
5. If an emergency of such a magnitude decreed that you needed to exit the plane at such an altitude, then probably the aircraft has suffered a structural failure and you would be pinned by the resulting G forces.

The environment at such altitudes is unbelievably harsh, despite what it looks like through the window, you would not want to go out there.

Answer 5

Airplanes are actually built to withstand a lot of damage and protect the passengers. The interiors of the planes are fire blocked and I believe they are developing air bags which fit inside the seatbelts which will help during a crash and whole airplane parachutes which would deploy in an emergency.

Answer 6

Too costly, takes up too much space and weight, and will need to be checked a lot, in case people tamper with them... To use parachutes, you need to be trained. The exterior paint on a 767 takes up about 300 pounds...

Well.... the 1 big parachute thing....
It would slow the aircraft down!

Answer 7

u cant crash on purpose unless u're a hijacker. and it's too expensive to get soo many parachutes. do u know the story about Titanic? i guess u'll end up in a situation like that if the plane DOES crash. anyway i don't think anyone except the pilot and co deserves a parachute

Answer 8

The best "equipment" is sitting up front. The highly trained pilots
are your best bet in the event of a emergancy.

Answer 9

Why not just one big parachute for the plane?

Answer 10

It would cost too much, take up too much space, add too much weight, and not do much good anyway.

Not to mention all the man-hours that would be wasted making sure they are all in working order every couple of months.
