Although advances in technology have made flights safer, we remain frightened by turbulence. You can only tighten your seat belt, grab the armrests and try to remember everything the stewardess said.
Then you will find out - the airline gave you a life jacket, but not a parachute!
Military aircraft and fighter jets always have parachutes on board, but commercial airlines do not have military jets, such as fighters, have several parachutes that passengers can use during emergencies.
In such situations, jumping from an airplane may be the only escape option.
On the other hand, a commercial aircraft such as the Boeing 737 can carry up to 200 people. Thousands of people around the world use these airliners every day to move from point A to point B.
So why don't airlines provide parachutes on board these aircraft for passenger safety? In fact, there are several good reasons for this. Let's get to know them.
Hollywood made us believe that jumping from an airplane does not require anything but bravado. In reality, parachuting is extremely complex, and requires many hours of training.
Even the most basic form of skydiving, known as tandem skydiving, requires at least an hour of training. Accelerated free fall is the most risky form of skydiving, it starts at an altitude of 3,000 to 4,000 meters above the ground. To do this, you will need even more specialized training and a lot of practice.
Moreover, jumping from an airplane in an emergency and skydiving for fun are not the same thing. The first is a matter of life and death, and the other, albeit a risky, but adventurous sport.
In addition, skydiving is carefully planned. Skydivers know in advance where they will jump, what they should do and when. Even a slight change in weather conditions can lead to cancellation of jumps.
On the other hand, while traveling by plane, ordinary passengers are not going to jump, and they don’t even know how or when to jump in the event of an emergency. Imagine the fear and chaos on board. Even such a basic thing, how to properly put on a parachute, may seem like a monumental task.
Airplanes that are used for skydiving are much smaller than commercial airliners. On the other hand, military aircraft are large and have a ramp at the rear. Skydivers use this ramp to jump safely while avoiding the fuselage.
Commercial aircraft have a different design. Jumping from such an aircraft is extremely risky, as it is easy to crash into the fuselage, especially into the wings and tail.
As mentioned above, skydiving is carefully planned and the height of the jump is one of the most important details. The highest point from which the paratrooper jumps is 4,500-5,000 meters.
Commercial aircraft fly at an average altitude of 11,000 meters above the ground. At this altitude, temperature drops and air becomes scarce.
Even if passengers can safely jump out of the plane, they need to have an oxygen cylinder, regulator, mask, altimeter, ballistic helmet and flight suit. Without them, they can lose consciousness due to a lack of oxygen.
The speed of commercial aircraft is another aspect that makes parachuting virtually impossible. During a flight at high altitude, a Boeing 737 can reach speeds of up to 1,000 km / h. Jumping from this height and at such a speed can be fatal!
Even one parachute is too bulky to fit under an ordinary economy class seat, and quite heavy. If you have ever flown, you know how strict they are with regard to the weight of your baggage, especially hand luggage. Now, imagine adding one parachute per passenger.
This will increase the total weight by 2.5 to 3 tons. Add the jumping equipment we mentioned above.
Parachutes and mechanisms themselves are quite expensive, and they need a lot of money. Of course, the airline will not pay for it out of pocket. They will include expenses in the price of air tickets.
Finally, most accidents occur during take-off and landing.
According to statistics, most air crashes occur during take-off and landing. Parachutes are useless when taking off and landing.
In general, having parachutes aboard commercial flights might seem like a good idea at first glance. However, if you think about it, this does not seem to be a practical or even viable proposal.
