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 altitude • Airspeed • Vertical acceleration • Magnetic heading • Control-column position • Rudder-pedal position • Control-wheel position • Horizontal stabilizer • Fuel flow

•The main purpose of the CVR unsurprisingly, to recordsounds that occur within the cockpit

•CVR communicate between the crew and ground control and other aircraft

Cockpit Voice Recorders:

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

•visualise how a plane was handling shortly before a crash.

•To help investigators find how crash the aircraft

•able to operate between -55° to +70°C and it can carries a minimum 25 hours of flight data.

•The device is activated as soon as the recorder comes into contact with water to it known as an Underwater Locator Beacon (ULB

ADVANTAGES

CONCLUSION:From the study of Black Box we derived a information that how the information about aircraft mishap is analyzed & unanswered question is answered.
