INTRODUCTION
The Black Box is a flight data recorder used to record specific aircraft performance parameters.
HISTORY
The first prototype of FDR was produced in 1956 by Dr. David Warren in the then Aeronautical Research Laboratories of Melbourne, Australia.
INSIDE THE BLACK BOX :
Flight Data Recorder (FDR)
Cockpit Voice Recorder (CVR)
Flight Data Recorders
The Flight data recorder (FDR) is designed to record the operating data from the plane's systems.
Parameters Recorded By Most FDRs: Time Pressure at altitude Airspeed Vertical acceleration Magnetic heading Control-column position Rudder-pedal position Control-wheel position Horizontal stabilizer Fuel flow
Cockpit Voice Recorders:
CVR is designed to track the conversations of the flight crew.
The Positions Of The Four Microphones:
Pilot's headset
Co-pilot's headset
Headset of a third crew member (if there is a third crew member)
Near the center of the cockpit, where it can pick up audio alerts and other sounds
Technology used for Recording and Storage:
Magnetic Tape
Solid-State Technology
Built To Survive:
In many airline accidents, the only devices that
survive are the Crash-survivable memory units
(CSMUs) of the flight data recorders and cockpit voice recorders. Typically, the rest of the recorder’s
chassis and inner components are damaged.
Testing a CSMUThere are several tests that make up the
crash-survival sequence: Crash impact
Fire test
Fluid immersion
Deep-sea submersion
Salt-water submersion
Pin drop
Static crush
Retrieving Information:
CONCLUSION:
From the data of Black Box we can understand that how the information about aircraft crashes is analyzed & unanswered questions are answered.
ANY QUESTIONS?
