What is a black clip on an airplane? What is an airplane black box

The so-called "black box" is a flight recorder installed on an airplane. In a plane crash, the aviation department always has to do everything possible to find the "black box" so that the cause of the air crash can be analyzed according to the data recorded by the "black box" and the audio recording in flight, so as to achieve the purpose of "making up for the dead", prevent the recurrence of similar accidents, and clarify responsibilities and do a good job in dealing with the aftermath. Satisfied.

The "black box" is one of the electronic recording devices dedicated to aircraft, and its real name is Aviation Flight Recorder. It is equipped with flight data recorders and cabin sound recorders, and all mechanical parts and electronic instruments of the aircraft are connected to them by sensors, just like the nerves in various parts of the human body communicate with the brain. It can record the relevant technical parameters and the sound in the cockpit half an hour before the plane stops working or crashes, and re-releases the recorded parameters when necessary for flight experiments and accident analysis.

The black box has strong resistance to fire, pressure, shock and vibration, seawater (or kerosene) immersion, magnetic interference, etc., even if the aircraft has been completely damaged, the recorded data in the black box can be preserved intact. All the causes of air crashes in the world are found through the black box, so it has become a witness to the accident and a "lesson from the past" to avoid the same accident and take better safety measures.

An orange-red box records the call records on board the plane and the flight parameters of the plane half an hour before the aircraft is false.

An instrument that records the voice of the aircraft, including the crew and passengers, and the various parameters of the aircraft.

The "black box" (English: black box) is one of the electronic recording equipment dedicated to aircraft.

There are two black boxes, the cockpit voice recorder and the flight data recorder. All mechanical parts and electronic instruments of the aircraft are equipped with sensors to connect to it.

It can record the voice dialogue of half an hour before the aircraft stops working or crashes and the flight altitude, speed, course, climb rate, descent rate, acceleration, fuel consumption, landing gear release, Greenwich Mean Time, as well as the working conditions of the aircraft system and the working parameters of the engine.

The shell of the black box has a thick steel plate and many layers of thermal and anti-impact and compression protection materials, and is usually installed in the safest part of the tail of the aircraft.

The recording medium has also been improved from a tape-based static storage recorder that can withstand greater impacts, similar to the memory chips in computers, to prevent the black box from being damaged in an air crash.

The black box is not only used in the aviation field, but also begins to be used in high-speed trains, which can record a number of real-time data information during the operation of high-speed trains, which is helpful for the investigation and analysis of accident causes.

The black box on the plane is orange. The scientific name of the "black box" is the flight recorder, and the reason why it is called "black box" is because all the electronic instruments in the aircraft at that time were placed in a black square box of uniform size and shape. However, black objects are not easy to find after a plane crash, and in 1962 the Civil Aviation Administration decided to paint the black boxes orange so that the striking "black boxes" would be easier to find.

Therefore, the "black box bright friend digging" we see now is not black but orange.

The "black box" is usually divided into two types, one is the flight data recorder. It can record the flight data of the aircraft, such as high register, speed, course, climb rate, descent rate, etc.; The other is the cockpit voice recorder, which can record all kinds of calls on the plane.

Generally speaking, these two recorders are installed in the tail of the aircraft, which is relatively easy to save in an air crash, and with the development of technology, both are equipped with underwater signal markers, which will automatically turn on after falling into the ocean at a certain depth, and emit a specific frequency of audio signals for seekers to determine their position using special receivers.

As an objective, true and comprehensive recorder of aircraft data, the black box is the most reliable, scientific and effective means to find out the cause of the accident after the plane crash. With the development of the aviation industry, the black box also plays an increasingly important role in the daily safety maintenance of aircraft, the monitoring of the status of the flight and the detection of accidents, and the location of faults, and can even be said to play an indispensable role in the flight process.

The black box is usually installed in the tail of the aircraft. Since the tail is usually the last part of the aircraft to be hit during a crash, the possibility of equipment survival is maximized. After finding the black box, the relevant data in the memory, the various factors are combined for systematic analysis, which can reproduce the cause of the accident to the greatest extent, and the eye-catching orange color makes it easier to locate after the accident.

Although the flight recorder is called a "black box", its actual color is orange-red to make it stand out and make it easy to find. The name of the black box can be traced back to 1954, when the idea of installing a sound recorder in the cockpit was first proposed, when all the electronic instruments in the aircraft were placed in a black square box of uniform size and shape. And the sound recorder is placed in the strongest black square box.

In 1957, the U.S. Civil Aviation Administration (later renamed the Federal Aviation Administration) mandated that all aircraft weighing more than a metric ton must be fitted with these enhanced flight recorders. Eight years later, the Aviation Authority decided to paint the "black box" bright red or orange so that the striking "black box" would be easier to find in the event of a plane crash.

By 1965, almost every airline in the world had switched to orange flight recorders, but the name "black box" was still used. In addition to being painted orange, some black boxes have reflective strips on their casings to make them easier to find, and say "Flight recorder, do not open".
