BLACK BOX

About:

• The black boxes are actually two orange metallic boxes containing the recorders.
  
  
• The black boxes date back to the early 1950s, when, following plane crashes, investigators were unable to arrive a conclusive cause for the accidents and deemed it necessary to install the said recorders on aircraft.
  
  
• Most aircraft are required to be equipped with two black boxes — the cockpit voice recorder (CVR) and the flight data recorder (FDR) — that record the information about a flight and help reconstruct the events leading to an aircraft accident.
  • The CVR records radio transmissions and other sounds in the cockpit such as conversations between the pilots and engine noises.
    
    
  • The flight data recorder records more than 80 different types of information such as altitude, airspeed, flight heading, vertical acceleration, pitch, roll, autopilot status etc.
