The airplane black box is a machine, or rather, an electronic
unit that is used in airplanes to record all of the information and data
related to the flight. This black box, which is not actually black but rather
orange or red to make it easier to find the plane if it is destroyed, allows
one to figure out what caused an incident or accident.
There are two types of black boxes
The parameter recorders used to record flight data and the
voice recorders, which are meant to record conversations in the cockpit. They
are positioned at the rear of the aircraft because this is typically the
component that will be preserved the best in the event of a ground or sea
impact.
Operation of a black box
A beacon that goes off in the event of immersion is included
in the black box: It sends out an ultrasonic signal to help locate the device
when the two contactors are wet. Over a distance of approximately 2 kilometers,
the signal travels at a frequency of 37.5 kHz at 160 dB per second for at least
thirty consecutive days. It very well may be gotten up profundity of up to
6,000 meters.
Year of the black box's introduction
Since 1960, the black box has been used in aviation. It
started out as a magnetic tape recorder and was gradually improved until 1990,
when it was replaced by SSDs (electronic disks that allow for the storage of
data). SSDs are thought to be more reliable because they can store more
information in a smaller space, making them easier to protect.
The black box's price
The black box is designed to not be destroyed in air
disasters and costs between 10,000 and 15,000 dollars. As a result, the data is
protected by three layers of materials made to withstand shock, fire, and deep
immersion.
Black box capacity
A minimum of 25 hours' worth of data from 28 to 1300
parameters (such as pressure, altitude, and so on) can be recorded in the black
box and can withstand a fire with a temperature of 1100°C for an hour and a
water pressure of more than 5000 bar. It has dimensions of 32 x 13 x 14 cm, a
battery life of 6 years, and a weight of 4.5 kg.
