Flight Data Recording System and Its Importance

In this study, the flight data recording system used in today's passenger planes and the connections between the elements that make up the system were investigated. Flight data recording system started to be used in airplanes later, but today it has become a necessity. Accidents in aviation, the cause and manner of which could not be clarified, caused a loss of confidence in the sector. In order to learn the cause of the accidents, to produce technical solutions, if any, and to reduce commercial costs, international civil aviation authorities have requested the recording of flight data. Flight data loggers were used as simple systems when they were first used on airplanes. In line with the development of technology and needs, it has become complex and has become a system that includes many components. Boeing 737, one of the most used passenger aircraft in the world, was chosen for the study. Although the system to be explained in the study is a Boeing 737 system, since a similar system is used in all passenger aircraft, the information given is generally basic information for all passenger aircraft.
