B) It is a time capsule in which records of important events are kept to be opened at a later date
C) It is a flight recorder in an aeroplane
D) None of the above
Correct Answer: C
Solution :
'Digital Flight Data Recorder' and 'Cockpit Voice Recorder' are kept in every aircraft, conducting international flights. These are used to find out the reason of accident if any. These are called black boxes, since these are kept separately in heat-proof and water-proof boxes. These instruments record the activities of the aeroplane. These records can be analysed to find out the exact reason of the accident.
