A flight data recorder, also known as a black box, records information about aircraft flights through sensors and can store up to 25 hours of data. It is built to survive crashes and is often found in the tail section of the plane. Together with the cockpit voice recorder, it provides a complete picture of flight conditions in the event of an accident. The data can help investigators determine the cause of the accident.
A flight data recorder (FDR) is a device that records information about aircraft flights. Also known as a black box, it receives data through a system of sensors related to altitude, speed, and a variety of other information. It records and saves this information about every flight the plane takes. The FDR is built to survive a crash with its data intact and is usually found in the tail section of the plane. In the event of an accident, this data is often very valuable and can help investigators figure out what happened.
Also known as an accident data recorder or ADR, the flight data recorder is one of two devices that records flight information. The other device is the cockpit voice recorder, which records all the conversations that take place in the aircraft cabin between the pilot and other personnel, and is capable of saving from 30 minutes to 2 hours of sound. The flight data recorder receives and records information about the aircraft itself and can store up to 25 hours of data. Together these two units are often called the “black box” and can provide information about the details of an aircraft’s journey.
The flight data recorder receives information about the aircraft’s operation from a network of sensors located throughout the aircraft. The received data is recorded; Depending on the age of the plane, it is saved on magnetic tape or electronically. A large amount of data is compiled to provide comprehensive information on whether the aircraft is working properly. This information includes the aircraft’s speed, altitude, acceleration, heading or direction, fuel flow and consumption, rudder position, and control wheel position. It also records electronic signals between the aircraft’s systems and operating data, such as the activation of various switches and controls.
The primary purpose of the flight data recorder is to provide a complete picture of flight conditions in the event of an accident when combined with the cockpit voice recorder. The unit is built to survive the extreme forces that can occur in crash situations, and can also survive exposure to fire and water. It is usually found in the area of the plane that is most likely to survive a crash intact, i.e. the tail section. Once the flight data recorder is recovered, investigators can use it to help recreate the events before a crash and can even create computer animations of the flight. Accident investigators can analyze the information to discover the cause of the accident.
