INTRODUCTION 

The Black Box is a Flight Recorder used to record specific aircraft performance parameters.

With any airplane crash, there are many unanswered questions as to what brought the plane down.   Investigators turn to the airplane's flight data recorder.(FDR) and cockpit voice recorder (CVR), also known as "black boxes," for answers.   In Flight 261, the FDR contained 48 parameters of flight data, and the CVR recorded a little more than 30 minutes of 

 

HISTORY

The first prototype FDR was produced in 1956 by Dr Dr.. David Warren of Aeronautical Research Laboratories of Melbourne,  Australia.

FLIG FLIGHT HT DA DAT TA RECOR RECORDERS DERS

The Flight Data Recorder (FDR) is designed to record the operating data from the plane’s system.

TECHNOLOGY 

Solid-state recorders are considered much more reliable than their magnetic-tape

counterparts.  Solid state uses state uses stacked arrays of memory chips   chips 

Boards are about 1.75 inches (4.45 cm) in diameter and 1 inch (2.54 cm) tall.

 

TRANSMISSION OF DATA

• Data

from both the CVR and FDR is stored on stacked memory boards inside boards inside the crash-survivable memory unit (CSMU). unit  (CSMU). • All of the data collected by the airplane's sensors is sent to the flight-data acquisition unit (FDAU) unit (FDAU) at the front of the

 

aircraft .

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.
