12105
TEST/DESCRIPTION

Computer Failure
Duration – 03:31
Introduction:

You are going to watch a film about an emergency situation caused by an onboard fire. The duration of the film is about three and a half minutes. After watching the film be ready to discuss it and answer the examiner’s questions.


1
00:00:00,000 –> 00:00:06,490
every time you board a plane you put
your trust in the pilots

2
00:00:06,490 –> 00:00:10,170
and every time pilots entered the
cockpit they put their trust in

3
00:00:10,170 –> 00:00:12,580
computers

4
00:00:12,580 –> 00:00:16,480
it’s a complicated relationship between
man and machine

5
00:00:16,480 –> 00:00:24,250
and when it doesn’t work perfectly
disaster can strike in an instant

6
00:00:24,250 –> 00:00:30,310
Lima Peru October the second 1996

7
00:00:30,320 –> 00:00:37,430
aero peru flight 603 prepares for
takeoff for Santiago Chile

8
00:00:37,440 –> 00:00:48,060
the plane is a four-year-old Boeing 757 a highly
sophisticated yet known for its reliability and safety

9
00:00:48,060 –> 00:00:51,140
the jet is among
a new generation of computer controlled

10
00:00:51,150 –> 00:00:55,670
aircraft in which pilots are trained to
rely on a central data system that is

11
00:00:55,670 –> 00:01:01,060
designed to reduce errors both
mechanical and human

12
00:01:01,060 –> 00:01:03,220
… gear up …

13
00:01:03,220 –> 00:01:07,940
Tonight though within minutes of
takeoff the flight begins to go horribly

14
00:01:07,950 –> 00:01:12,040
wrong

15
00:01:12,040 –> 00:01:17,220
the altimeter indicates how high the
aircraft is flying over the ground it

16
00:01:17,220 –> 00:01:22,700
it reads 0 but the plane is clearly
airborne

17
00:01:22,700 –> 00:01:33,560
as the two men try to solve the first problem they lose another crucial
instrument the airspeed indicator

18
00:01:33,560 –> 00:01:40,180
They will do it by the host of confusing warnings
captain Schreiber decides to land

19
00:01:40,190 –> 00:01:41,640
to add to their problems

20
00:01:41,650 –> 00:01:45,870
Shriver and Fernandez are flying at
night over water with no visual

21
00:01:45,870 –> 00:01:49,590
reference points

22
00:01:49,590 –> 00:01:53,270
able to trust their instruments the
pilots have to depend on information

23
00:01:53,270 –> 00:01:55,920
from the ground

24
00:01:55,920 –> 00:02:00,040
even as they tried to return to the
airport the havoc in the cockpit gets

25
00:02:00,050 –> 00:02:08,750
worse now the storm warning sounds

26
00:02:08,750 –> 00:02:11,760
and then

27
00:02:11,760 –> 00:02:15,959
the ground proximity alarm warns them
that they’re flying dangerously low

28
00:02:15,960 –> 00:02:20,520
Investigators managed to find the data recorders.

29
00:02:20,520 –> 00:02:25,320
was clear to us that there what they
were really experiencing a problem with

30
00:02:25,320 –> 00:02:30,580
airspeed and altitude

31
00:02:30,580 –> 00:02:37,940
on the 757 devices called pitot static
tubes measure the airspeed and altitude

32
00:02:37,940 –> 00:02:41,800
their small external sensors which relay
that information to the plane’s

33
00:02:41,800 –> 00:02:48,590
computerized systems

34
00:02:48,590 –> 00:02:54,770
deep underwater tape is discovered
covering the plane’s sensors

35
00:02:54,770 –> 00:03:01,720
just before aero peru 603 lifted off from lema
maintenance workers had cleaned the jet

36
00:03:01,720 –> 00:03:06,280
a worker had covered the static ports
with tape to protect them

37
00:03:06,280 –> 00:03:11,170
this is standard procedure but when the
maintenance was complete

38
00:03:11,180 –> 00:03:14,320
the worker forgot to remove the tape

39
00:03:14,320 –> 00:03:24,240
it was a small oversight with tragic
results

40
00:03:24,240 –> 00:03:29,060
Aero Peru was a deadly lesson about how
dependent pilots have become

41
00:03:29,060 –> 00:03:30,560
on their automated flight systems

    The investigators found a tape on static ports which led to disaster.

  • Sergey Rastorguev

    I agree with you. The crashed cause by maintenance error.

      9) Was it the only problem onboard Flight 603?
      No

      10) What is the function of the altimeter?
      The altimeter indicates how high the aircraft is flying over the ground.

      11) What are the other basic cockpit instruments?
      What function do they perform?

      12) What caused the confusion of the flight crew?
      The flight crew was confused by warnings.

      13) What warnings did they have in the cockpit?
      The pilots had a problem with airspeed and altitude. Moreover the storm warning and the ground proximity alarm warned them that they was flying dangerously low.

      14) Did these warnings help them to realize what was happening?
      No
      15) What did the flight crew intend to do in that situation?
      Captain Schreiber decided to land.

      It was clear to them, that pilots were really experiencing a problem with airspeed and altitude.

      17) What caused malfunctioning of the Pitot tubes?
      The plane’s small external sensors were covered with tape.

      18) How did this failure contribute to the crash?
      It was a small oversight with tragic results.

      19) What did the crash of Flight 603 prove?
      It proved how pilots became dependent on their automated flight systems.

      20) In your opinion, was the reason for the crash a technical problem or a human error? A humane error?? absolutely, yes.

      21) Do you agree that human error is the main factor for accidents in aviation?
      Can you think of any examples?
