He is the only and just witness after God Almighty on the crash of the plane and the reasons behind the plane crash. He does not accept fraud and deception unless it stands behind human hands that change the course of facts, as is the case in the crash of the Egyptian plane and the Gulf Air plane in Bahrain. The real reason behind the crash of the two planes is not known. to today
Black Box Specifications
It consists of two recorders, one theoretical and the other digital, and they are similar in outward appearance and differ in composition from the inside
The dimensions of the two boxes are 20 inches long, 5 inches wide and 7 inches high, and are in the plane's tail to increase protection for them
reason of calling
It was called the black box due to its association with air disasters and plane crashes, and it is in fact an orange box
History of the fund and its benefits
The box records everything large and small inside the plane from the plane's altitude, air speed, compass direction, temporal and vertical acceleration, and is measured by gravity 9.80665 meters per second squared
The US Federal Aviation Agency has adopted these standards in licensing the manufacture and operation of aircraft on airlines
The first black box recorder was manufactured in 1958 AD and the factory was Lockheed Corporation and it was the first theoretical flight information recorder and was resistant to crash, which is F.D.R (Flight Data Decoder), then another company produced a cockpit sound recorder, C.V.R
The Federal Aviation Administration ordered a digital recorder in the early 1970s under the name D.F.D.R (Digital Flight Data Recorder)
It is able to record no less than 17 types of information, and after the development of theoretical and digital recorders, it can record at least 100 types of information at one time by receiving the information through the sensing devices. The plane and the plane is in the air, and all this is related to a recording needle that records all occurring and emergency pressures, which is like an ECG needle
Black box benefits
Black box information is used before
1- Aeronautical engineering departments to monitor aircraft performance and improve their maintenance level
2- Departments of aviation navigators to promote the level of navigators
3- Aircraft manufacturers to raise the safety level of modern and old aircraft
4- The information in the black box is useful to meteorologists as it provides accurate information about dangerous weather phenomena such as air shears and small air blasts.
Black box scientific specifications
In the black box there is scientific and technical progress that is similar to imagination, as it is the only evidence that provides investigators with the required parameters after the crash of the plane and that they must be available after the accident to know the causes of the disaster and it is the most expensive piece in the plane and includes the following specifications
1- It is orange in color and is covered with light reflective strips
2- Withstands temperatures up to 1100 degrees Celsius fired by a fuel-fed flame for 30 minutes
3- The boxes are made of titanium. They penetrate a steel bar weighing a quarter of a ton, falling from a height of 3 meters
4- The vibratory vibration does not harm or lose the recorded information
5- It contains a radio beacon to determine its location under the water and emits high-frequency light pulses of 37.4 kilohertz when touching the water and dense and humid snow and that when leaving the tail of the plane and that signal can be distinguished from a distance of 2.5 miles and a depth of 20 thousand feet under water for a continuous period of 30 days
6- It has a good quality information recording tape with a quarter inch width and a continuous recording capacity for 25 continuous hours. It returns to record again after the end of the period and over the old information and it is scanned automatically and there is also a cockpit recorder in the cabin of the aircraft
Registered cockpit
It records the latest events that led to the plane’s crash. It knows the investigators if the pilots felt there was a defect in exchange for the plane’s crash and what quality. It allows comparing the information in the black box with the cockpit recorder. It records the navigators ’calls from the operation of the plane’s electrical network until it stopped working for a period of half An hour, which is a short period compared to the black box, it records the most important penalty, which is the penalty that is very close to the event
Registered cockpit capabilities
It records everything that falls in its range, including the 400 hertz resonances from the 28-volt network, the sounds of the cooling fans, and the weak vibrations
