Global aerospace and marine data recorders are used in commercial and defense applications. Aerospace and marine data recorders are segmented into flight, cockpit, and voyage data recorders. While cockpit voice recorders record radio transmissions, pilot's voices, and engine noises; flight data recorders record performance parameters of planes, such as time, altitude, fuel levels, and airspeed. Similarly, voyage data recorders record wind speed and direction, ship's location, and the direction in which the ship is heading. These recordings are retrieved and analyzed during investigations of accidents.
