Types of Black Box In Aircraft

Aircraft have two types of boxes in the tail of the aeroplane, one is a Cockpit voice recorder (CVR) and another one is a Flight data recorder (FDR). These two black boxes have different functions in the aeroplane. If an aircraft has an accident, then to investigate that event, we use the data from the black box. Both of the boxes are installed in the aircraft, one is installed in the front of the aeroplane and the other one is installed in the tail of the aeroplane.

1. The Cockpit Voice Recorder- The first black box is called the cockpit voice recorder box which records the radio transmission and sounds in the cockpit. The recordings are made on a loop and overwrite the oldest recordings. The Cockpit voice recorder can record up to 30 minutes of audio.

CVR keeps two microphones one for each pilot. These microphones can record and detect sounds in the cockpit such as engine oil, pilot conversations, and warnings from the aircraft system. The top part of the cabin is equipped with various microphones. Earlier CVR was used as an analogue storage system that can only record and store about 2 hours of audio. The modern CVR uses a digital storage system that can store up to 25 hours of audio. The quality of the audio recording is very high and can be used to identify voices. 

2. The Flight Data Recorder- The second box is the flight data recorder which records the parameters related to the flight like Attitude, airspeed and Heading. FDR also keeps information about the operation related to aircraft systems such as the use of flaps and landing gear. The data which is recorded in FDR is used to help investigate accidents and incidents.

The Flight Data Recorder have a solid-state memory device and a digital data recorder. The memory device of FDR stores data in non-volatile memory, which means that the data is not lost when power is lost. There is also a digital data recorder which records data in format form that a computer can read. FDR is located in the tail section of the aeroplane. The FDR is stored in a container that is made of stainless steel and titanium. According to the Federal Aviation Administration or the FAA, the FDR should be able to record at least 25 hours of data. All the data recorded in FDR is used to help prevent future accidents and incidents.
