Why dont they provide Parachutes on passenger airplanes like Boieng 747 ???

Question

Y don they give each passenger a parachute in an airplane ?

Answer 1

It is hard enough to get out of an airliner on the ground when the plane is standing still at the gate now imagine 300 panicked idiots that did not listen to the flight attendant's briefing trying to figure out how to use a parachute for the first time then imagine that the airplane is moving around tossing you up and down and back and front now we come to the fact that in a pressurized aircraft you can not open the doors until it is depressurized oh yeah and you are flying at 400 MPH hope you don't hit the tail or get sucked into an engine on your way out. More people would die attempting to exit the aircraft than if they rode it in during an emergency landing!!!!

Answer 3

Because, apart from rare occurence of trouble in midair, like the fire on board SwissAir 111, most accident occur on takeoff or on landing, i.e. at altitudes that are way too low of a parachute to even deploy completely.

How about other circumstances, like SwissAir 111? In that case, the airplane was above the ocean, at night. Not an ideal time and place to go skydiving.

Jumping off a plane flying at high speed requires an ejection seat, and if the plane is high, oxygen supply and insulated clothes. Jumping from a side door of an airliner is almost guaranteed to have the jumper hit the airframe at some place.

Basically, someone trying to jump has less chance to survive than someone staying on board the aircraft.

Have you ever jumped with a parachute? The first couple of jumps, the parachute opening is automatic, but you have a handle that you must pull to prove you did not panic and demonstrate that you CAN deploy the parachute. It is only after you've done in a couple of times (that is pulling the mock handle) that a person is allowed to deploy the parachute themselves. Now imagine 200 people trying to jump at the same time, pushing and shoving through the aisles, with some &^%# insisting on bringing their luggage with them, and trying to do a parachute unit, knowing fully well that they did not pay any attention to the security speach given by the crew in the first place... And then, how to you handle the massively overweight passengers who can be on board, and the toddlers?

Oh, and by the way, do you know how much a parachute costs? About $1000.

Answer 4

Good question. Because parachuting requires training. The altitude and speed would make un-survivable. It would be impossible to in an orgainized manner to get everyone out the doors. And usually the emergencies happen too fast (flight 800). But how about this? Segment the aircraft into 6 sections with a parachute for each section. Then the plane could break apart and each section of 50 people would be "parachuted" to safety. They have "plane chutes" for small planes. Why not the big ones?

Answer 5

So what good is parachuting without proper training beforehand? Also, how long does it take to exit the plane? Do you think everyone's going to have enough time to jump out of the plane? It's just not feasible. Also, if you're over the ocean, where do you propose landing? You now have jumped out of a plane without a life preserver... Do you plan on treading water for hours or days until someone finds you? You could be MILES from where your plane was last detected on radar. There are plenty of plane crash survivors. It happens. But, if you slam into the side of a mountain (as the Russian flight did), you're not going to survive. And no one knows if the pilot detected any trouble. People at the control tower only knew that it disappeared on the radar. The pilot likely didn't see anything when they slammed into the mountain. How would parachutes have helped? There's a risk of taking any kind of travel. Air Travel is still one of the safest possible forms of travel.

Answer 6

Let me ask you...how often do you fly? I do quite frequently...floatation devices are always available to all passengers in case of a water landing...and more times than not, passengers are reading, talking and frankly, annoyed every-time a flight attendance runs over the instructions for their use. Now, you want to add a parachute...and to be deployed in flight? And to do what? I am afraid that in the latest a/c accidents, neither a floatation device nor a parachute would had made a difference.

So, the short answer is, there is no safety requirement for a parachute in a plane for anyone (unless you are in a military mission and your job is to jump out of a perfectly operating plane).

Answer 7

Been thinking the same thing few years back. Cos maybe they dont have a large exit door for jumping out. Then once ppl panicked, they wld be all out of their seat belts putting on the chutes, and this could cause major chaos of the plane were to experience a dive. And landing in the middle of the ocean wouldnt do u much gd either. But these are just my personal theoris that i speculated after reading ur Q.

Oh yah and skydivers need experiences and a licence or smth. So with such a small exit, and little experience, they wld jam the exit door. Not eveyone is brave enough to jump out of a plane.

Answer 8

The simple answer is that parachutes in the hands of people without any training is more dangerous than riding an injured airplane into the ground. In the latter situation, there is a chance of survivability especially seeing as the pilots of commercial airliners are so heavily trained in emergency situations.

Answer 9

Are all of you who ask this question insane?

Planes fly in excess of 30,000'. The temperature at this altitude is around -40 deg. Farenheit. The only breathable air is 4-5 miles below you. First you would pass out from lack of oxygen, then it would be a race between death from lack of oxygen and death from hypothermia. Either way you're dead long before you hit the ground.

You are a million more times likely to get in a car crash on the way to/from the airport than being in a plane crash. Why don't you worry about that instead.

And PLEASE DO NOT ask why they don't make the airplane out of the same materials as the black boxes.

Answer 10

Hello,

jet aircrafts travel at such high speeds, that climbing or jumping out whitout a rigid protection causes the subject serious or fatal injuries. At e.g. 600 km/h, when you put your head out, you experinece a force of approx 40-45 kg's of wheight, which brakes your neck for sure. Jet pilots are ejecting strapped into their seats for similar reason (1. protect the pilot from heat, debris, collision with the aircraft. 2. maintain safe body position and protect limbs, head and the body). Another factor is, that at such altitudes, temperature, pressure, and oxigen concetration levels are very low. Civil passengers with regular clothing are simply unable to survive the cold. The lack of oxigen kills anyone sooner than you reach the altitude of sufficient oxigen levels. From aircrafts travelling above approx 15,000 metres you have no chance to survive without pressurized suit (the effect is similar to the 'bends' (decompression sickness) known among scuba divers, but in reverse, e.g. blood starts to boil at approx 20,000 metres !!!)

Thus, giving the passengers parachutes solves only the problem of body identification (with no missing limbs or heads).
