 Drawbacks
 Beyond Black Box
 References

3.  The original black box was designed by David
Warren.
 In 1953, Warren came up with the idea of an onboard
flight-data recorder.

4.  It is a Flight Data Recorder.
 It record's specific aircraft performance parameters
and conversations in the cockpit.

6.  The Exterior of the FDR is coated with heat-
resistant Bright Red paint.

7.  There are two Black-Boxes Flight Data Recorder &
Cockpit Voice Recorder.

8. MAGNETIC TAPE
RECORDER
SOLID STATE
RECORDER
 Introduced in the 1960s
 It can track about 100
parameters.
 Magnetic-Tape CVRs store
the last 30 minutes of
sound.
 Introduced in the 1990s
 It can track more than 700
parameters in larger
aircraft.
 CVRs that used solid-state
storage can record 2 hours
of audio.

10.  Time
 Pressure altitude
 Airspeed
 Vertical acceleration
 Magnetic heading
 Control-column position
 Rudder-pedal position
 Control-wheel position
 Horizontal stabilizer
 Fuel flow
Few parameters recorded by most FDRs:

11.  The unit is usually mounted in the aircraft's
empennage (tail section).

12.  These recording devices cost between $10,000 to
$15,000 each.
 Both Black Boxes are powered by one of two power
generators that draw their power from the plane's
engines.
 The Memory boards have enough digital storage
space to accommodate 2 hours of Audio data for
CVRs and 25 hours of Flight data for FDRs.

13.  In Airline accidents, the only
devices that survive are the
CSMU.
 CSMU
 Three layers of materials in
CSMU:
 Aluminum housing(0.25
inch)
 High-temperature insulation
(1 inch)
 Stainless-steel shell (0.5
inch)

14.  Crash Impact
 Pin Drop
 Static Crush
 FireTest
 Deep sea Submersion
 Salt water Submersion
 Fluid Immersion

15. Underwater Locator
Beacon (ULB)
 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.

16. 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.

17.  Retrieval comes first.
 Help identify the reasons for a plane crash.
“Mistakes are a great educator when one is
honest enough to admit them and willing to
learn from them”
