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?
