INTRODUCTION
BLACKBOX is a Flight Data Recorder.
It records specific aircraft performance parameters and conversations in the cockpit.
HISTORY
The first prototype FDR was invented in 1953 and was produced in 1956 by Dr. David Warren at Aeronautical Research Laboratories of Melbourne, Australia.
Parameters Recorded By most of the FDRs:
⃗ Time
⃗ Pressure altitude
⃗ Airspeed
⃗ Vertical acceleration
⃗ Magnetic heading
⃗ Control-column position
⃗ Rudder-pedal position
⃗ Control-wheel position
⃗ Horizontal stabilizer
⃗ Fuel flow
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
Working of Black Box
Submergence sensor on the side of the beacon.
Pulses at 37.5 kilohertz (kHz).
sound as deep as 14,000 feet (4,267 m).
Once the beacon begins "pinging," it pings once per second for 30 days.
Retrieving Information
This portable interface can allow investigators quick access to the data on a black box..
Retrieval of FDR
Retrieval of CVR
Once the beacon begins "pinging," it pings once per second for 30 days.
CONCLUSION
From the study of Black Box we derived a information that how the information about aircraft mishap is analyzed & unanswered question is answered.
In this study we discuss about various technology various aspects involved in black box.
