The flight recorders – devices which are intended to preserve the characteristics of the flight and talks in the cockpit. The device is an electronic unit that produces a recording on digital media. The system is protected in a sealed housing made of metal. The flight data recorders able to stay sufficient time in the most adverse conditions.

History

The First logger created in France. In 1939 Useno F. and Beaudoin has developed the oscilloscope, which recorded each deviation of a parameter of flight by rays of light. 14 years later the Australian science D. Warren, participating in the investigation of the crash of a passenger plane, came to the conclusion about the necessity record of negotiations of pilots.

flight recorders

The Idea came to a real invention after 3 years, in 1956. the flight data recorder was protected with asbestos and steel case. In 1960, Australia has put the requirement that the installation of the recorder in the planes was binding. Other countries followed the example of the Green continent.

Common myths

The media broadcast about each crash of the aircraft in all available details. Perhaps, everyone has heard about the black box. The flight data recorder actually works is not quite as accustomed to imagine the average person. Main created myths about the black box:

  1. The logger is not actually black, but orange. The color is chosen based on ease of detection of the recorder under the conditions of the crash.
  2. The drawer is not a drawer: the Registrar is a ball or a cylinder. The spherical shape allows to withstand the maximum allowable load.
  3. Usually to obtain the recorded information is not required interpreter. Data is actually not encrypted. Listen to them is able to absolutely anyone. However, only the expert can analyze the obtained information.

Now, readers should have the correct view of how to look at the flight data recorders in fact.

black box flight recorder

Modern ships provided by two on-Board recorders: the voice and parametric. Use advanced operational set of registrars.

Purpose

The flight recorders intended for the collection and storage of the navigation parameters, information about the ongoing actions of the crew and the material condition of the aircraft. Modern recorders can capture the following settings:

  • Pressure of the liquid fuel feeding to the engine;
  • The pressure in each of hydraulic systems;
  • Engine speed;
  • The temperature space of the turbine of the aircraft;
  • The use of military buttons;
  • Deviation of the control devices and its degree;
  • Using the landing mechanisms;
  • Speed, altitude, flight path;
  • The passage of beacons.

Record flight parameters and cockpit simplifies the investigation of the causes of the crash. It not only allows you to understand the flaws of the design, but also to develop a plan of action in emergency situations, to analyze the incident, the crash from every possible angle.

Device flight recorder

The logger depends on the destination and method of recording information. Distinguish optical, magnetic, mechanical, and electronic storage devices. Mechanical and optical recording methods are obsolete, currently they are not used even on older models of aircraft.

where are the flight recorders

Electronic recording systems represent an accumulation of memory chips and a controller that is very similar to the SSD in a typical notebook. Recorders with the device of the electronic type are installed on all modern aircraft and constitute a large part of all of the registrars. The older models still applied method for magnetic recording using tape or wire. The latter is the more reliable option.

the flight data recorders of the fallen planes

Externally, the flight data recorder protected by a metal shell made of alloys of titanium or alloyed iron. Service and test recorders are used without additional coatings. Appearance will depend on which types are the flight data recorders. Photo allow to study in detail each type separately.

The Safety of registrars due to the fact, where are the flight recorders. According to statistics, less accidents in the airspace suffers from the tail of the aircraft. It is this reason due to the location of flight recorders in aircraft at the tail of the fuselage.

Start up

Access maintenance recorders are available only to employees who are not interested in the distortion data. Crew members may not be able to turn on or off the record. In order to run automatically creates a relationship between the operation of the recorder and the actions of the aircraft. There are several types of activation registrars:

  • When you start the aircraft engine;
  • Under the action of the limit switch;
  • With the help of speed sensors.

Write data forthe flight data recorders depends on the method of recording information. Typically 30-120 minutes at a certain point of the flight.

Types of recorders depending on the purpose of the application

Operational flight recorder used during regular scheduled flights to obtain objective information about the state operated aircraft, and for independent evaluation of the work of the crew. A recorder of this type is not protected against environmental influences in the crash.

how to look like the flight data recorders

The Emergency flight recorder - the mechanism, which all repeat in a plane crash. Before operation carry out the test, showing how the device is resistant to the critical conditions. The flight data recorders of the fallen aircraft must be capable of:

  • To be in aviation fuel 24 hours;
  • 60 minutes to burn in the fire (1100 °C);
  • Be at the bottom of the ocean (6000 m) within one month;
  • Withstand statistical overload on each axis in the 2168 kg.

After conducting a thorough inspection of the flight data recorder allowed for installation in the aircraft.

Test data logger are used to assess the performance of the aircraft. Used when conducting the test flights with the aim to identify possible design flaws. During passenger flights does not apply.

The flight recorders

Modern aircraft are equipped with two types of recorders: the voice and parametric. Often design involves the combination of different types of information in a single flight recorder. Both speech and parametric device has a clear relationship with time.

Parametric recorders able to record over 2000 data, but is used of which only about 500. Limiting the number of logged parameters is because they are not applicable to the investigation of catastrophes. Recorders of this type are some of the main signs of failure of aircraft and the objective evidence of the causes of the accident.

Voice recorders record the conversation between the crew in a certain period of time. Used to identify and eliminate the human factor in aircraft accidents, and to improve and evaluate professional skills.

Search recorders after the crash of an airliner

Loggers are equipped with a special beacon based on ultrasonic waves that aktiviziruyutsya in case of danger (e.g., in contact with water). The signal's frequency is 37.5 kHz. If the crash happened away from the water, find the recorder is not difficult.

device flight recorder

The Bright color is well visible on the background of the wreckage. High wear resistance allows not only to detect the ball or the cylinder of the Registrar in relative safety, but also to decrypt the data.

Possible recovery of Registrar in case of breakage?

About a third of all accidents lead to the violation of the integrity of the housing the flight recorder, which entails a loss of information. In some cases, laboratories are held a long and serious work on the restoration of damaged parts of the recording devices.

location of flight recorders in aircraft,

Methods based on sealing or application of adhesive. Sometimes the renovation help and information possible to restore.

Improved technology

The Invention originated over 50 years ago. To see if during this time the analogues that can replace the flight data recorders? No, by far the most reliable and informative method to record the necessary characteristics of the aircraft. Developed separate mechanisms of registrars, but the General principle remains the same.

Device memory improving, developing electronic media. The planned creation of videos separate compartments, allowing you to more closely monitor the situation and evaluate the results.

Scientists consider options for the establishment of shoot and floating recorders. It is necessary to provide the device with the sensors that will be able to fix the collision of the aircraft with an obstacle. Received the distress signals will start the mechanism of catapultati of dangerous places.

Interesting idea broadcast recordings online on a remote server. This will reduce the time of decoding, allow faster response to emergency events and have full access to information in real time.

The flight recorders – one of the most important inventions of the post-war technology. The data obtained from registrars of the destroyed planes help to study the main mechanisms of accidents and to minimize the percent of incidents. In the cases of the attack on the airliner flight data recorder can confirm guesses forensics about the attack or combat operations in the airspace.
