Question

why don't the design of the airplane include seats with automatic parachutes ? also design a roof could be open, so that in the event of emergency, the pilot / captain could press a button to open the roof of the plane and shoot 300 people out from the plane with the right height it may work with those parachutes tied with the seat. At lease 50% may be saved ? better then all die...

Answer 1

Why do they allow this c**p?

Answer 2

money

Answer 3

Because the parachutes are underneath the seats anyway

Answer 4

Why don't dweebs like you do a search before asking this same bloody question every day?

drwer:  It was Aloha Airlines, and ONE person, Flight Attendant CB Lansing was blown out of the aircraft.  She was the only fatality.  I was once a railroad engineer, and I would rather fly.  I KNOW how dangerous rail travel can be.

Answer 5

A very good question.

Really, you should have patented the idea, and try to sell it to a large aircraft manufacturer, make millions of pounds, and let them work out the problems with it.

But, by asking us, you get answers from all sorts of riff-raff.

Ok, here is my answer:

1)The seats would be heavier

2) It would cost a lot to make

3) The parachutes would probably get tangled, and you'd have a 300-person dead weight dropping from the sky.

4) There is no oxygen in the air above 10'000 feet, so you would have to install portable oxygen mask as well, or else everyone would suffocate.

5) Most crashes result in hitting the ground hard and fast, in which case a parachute would be useless.

Answer 6

do you know that the ejection seats make some 35gs during the launch? it is a moment yet even the trained and able bodied pilots may suffer from compressive wounds of the spine.

plus the seat would weight approx 50-80 pounds

plus the hull is not possible to create open and pressure tight at the same time

plus the seats would need more space

plus some people simply would not fit the seats

plus the children would need special seats

plus the launch sequence with .5 second separation still would need 150 seconds which is 2.5 minutes to eject one by one. you cannot fire more than one at a time to make separation between the seats

Answer 7

Very few commercial airline disasters happen at altitude. Most happen at or soon after takeoff and landing -- no time for parachutes. In case of problems, it's actually  safer to stay with the plane.

Answer 8

An untrained person would be far better off riding the aircraft to the ground rather than the certain injury resulting from the force of the ejection seat.  It takes a high degree of training to be able to safely eject from an aircraft, and even then it is not always the best result.

Answer 9

Yes, I think the FAA and passengers would be interested in a design that "shoots 300 people out of the plane" .  Yep, we could sell that for sure.

Yes, ladies and gentlemen,  for your added safety, there is an explosive device attached tothe bottom of each seat, which in the event of a very likely failure of our aging aircraft, will blow a hole in the roof and shoot you out like a roman candle.  Then, using a parachute packed during construction of the plane, and never tested since, will deploy.  immediatly reducing your airpseed from 500 mph to less than 30 mph in say 5 seconds....the pliant seatcusions absorbing the resultant 100+ g forces be for touching down god now where.

Its fairly impractical, expensive, and uneeded since the risk of dieing in a plane accident is exceedingly small even compared to other forms of travel.

Only Dan Rather could convince people that air travel was inherently dangerous when he said of the Hawaiian Airlines accident...." We can only imagine the horror as these people were SUCKED OUT THE GAPING HOLE'".  

If you dont like to fly....take a train....Amtrak....now thats safe.
