Secrets of airliners

Aviation is the most modern and fastest among all modes of transport. In the sky are constantly thousands of aircraft that can deliver people to virtually anywhere in the world. Airliners are a genius creature of mankind, in this machine all the most advanced technologies are collected. Sometimes it even seems surprising and strange that this is all available to almost anyone.

Aircraft fly millions of people, without even thinking, what a number of ingenious inventions and secrets they surround on board. And this invention to a great extent brings together and unites. True, our knowledge of airliners is often based on some general information. But these giant planes have many interesting secrets.

Secrets of airliners

There are explosive charges inside the engine.

It turns out that inside the engines of such aircraft are pyro-cartridges. And their function is to prevent fires in engines. Aircraft usually have two such charges. The second one is duplicating. If the first charge fails, then its replacement will still allow the aircraft to win several necessary minutes until a landing site is found.

The aircraft may have hidden serious damage.

We look at the handsome liner and we do not suspect that it can have very serious breakdowns. Companies benefit from having their aircraft fly as often as possible at full load. Quality repairs are not carried out in a few hours, it stretches for whole days. The document MMEL (Master Minimum Equipment List) records all the faults detected on the liner. If passengers had the opportunity to get acquainted with such a list, few people wanted to travel by this plane. For example, the system allows takeoff of the liner even with half of the potentially working systems. But the final decision on the possibility of departure takes only the captain. But no one prevents the owner from finding a pliable employee.

The air in the interior comes from the engine.

In the cabin of the air the air is not at all what is outside. The fact is that at high altitude the air is discharged and is unsuitable for breathing. People need to be constantly conscious. For this, air and air are supplied to the cabin and cabin, which passes through the engines and is compressed after this.

Emergency decompression is a very dangerous phenomenon.

It is no coincidence that pilots are advised to put a mask on their faces before they help others. And this is an extremely important piece of advice. At altitude, there is such a rarefied air that in the case of emergency decompression in the mind it will be possible to remain only 30-45 seconds. And at an altitude so cold that the air temperature can reach 60 degrees below zero Celsius.

Oxygen masks – help on time.

The masks themselves are such that they can work no more than 12 minutes after they are unpacked. During this time, pilots need to drop to the altitude, where you can already breathe normally. Yes, and the mask does not protect against gases or smoke.

Life rafts.

The operating principle of liferafts seems so simple that few people study the safety instructions while on board the aircraft. The figure can be depicted people who are holding the raft with one hand. They swim nearby, and do not sit on top of the rescue equipment. This is important to note, because the raft will overturn if someone tries to climb on it.

Security certificate and bribery on tests.

When airlines conducted tests with training evacuations of passengers, a dead end unexpectedly appeared. Participants in simulated critical events behaved very calmly and even politely with each other. But this was not at all like a real situation. Researchers thought about how to cause people a real sense of desperation. It was found that it is enough to promise a reward of $ 30 to each participant for getting out first from the salon.As a result, a plausible situation was created, people behaved like average passengers in a pushed and panicking crowd, striving to get out.

Prohibition of the use of portable electronics.

In recent years, airlines have increasingly canceled the ban on the use of portable electronics by passengers during the flight. Just officials finally listened to common sense. Gadgets in no way affect the technique of the liner during long flights. Evidence that mobile devices somehow affect the electronics of the aircraft, it was not found. The probability that such a danger really exists is minimal.

Mobile devices of pilots.

Mobile devices do not really carry the flight, but in the case of pilots’ gadgets, the situation is quite different. A call to the pilot’s phone at the time of landing in the form of a sound signal or even vibration distracts from an important maneuver. Once a pilot in this situation even forgot to release the chassis, endangering the lives of dozens of people.

Secrets of airliners

The minimum fuel.

This term usually refers to the volume of fuel that is enough to fly accurately between two desired points. But international law says that the liner should have enough fuel for the actual flight, and also some additional volume for unforeseen circumstances. This is 3-5% of the bulk of the fuel. “Alternative fuel” – the volume provided for a leak. And even in addition to these additions, there is still fuel, which is enough for half an hour flight. So the pilots’ time always has options for changing the landing site in an emergency.
