The iris (eye colored part
controls the amount of light allowed to enter the eye
2
One of the environmental factors affecting clarity of sight is
amount of light available
3
The cornea is responsible for between
70%and 80% of the total focusing ability of the eye
4
After passing through pupils the light passes through the
lens
5
A concave spectacle lens overcomes
short sightedness (Myopia)
6
convex spectacle lens is used to correct
Hypermetropia
7
Color defective vision
affect about 8% of men but only 0.5% of women
8
Hypermetropia is an
eye defect long sight
9
If a task is performed often enough it may eventually become automatic is known
as motor programmes
10
The capacity of long term memory appears to be
unlimited
11
The basic function of the ear
to detect sounds by receiving vibrations in the air
12
Aural reflex inside the middle ear, helps
to protect the ear from loud noise
13
Diffusion of responsibility is possible when responsibility is given to
group of people
14
is the regular behaviour of an individual
Habit
15
result in the workplace
The immediate reward has a positive effect
16
Demotivated people tend to demonstrate
unjustified resistance to change
17
Self actualization
is the peak of maslow’s hierarchy of needs
18
Peer pressure is the actual or perceived pressure which an individual may feel, to conform to what he believes that his
colleagues expect
19
Maintenance Resource Management (MRM) considered human factors of
maintenance engineer and managers
20
In management of stress, coping strategies (facing) may be
positive or negative
21
The affects of jet lag can be minimized
by avoiding alcohol and caffeine
22
Drinking 3-4 unit of alcohol before sleeping results
in loss of quality sleep
23
Deep sleep occurs earlier in the night, REM sleep
becomes greater as the night goes on
24
slow weave sleep
stage 2-4 sleep
25
Human factors refer to the
study of human capabilities and limitations in the workplace
26
Anthropometrics (the scientific study of
measurements of the human body
27
If familiar tasks (such as programming the video recorder) seem more complicated than usual is early indication of
chronic fatigue
28
Day to day fitness and health can be
reduced through illness (physical or mental ) or injury
29
Illumination can be defined as
the amount of light striking a surface
30
Supplemental lighting must be adequate for the task which
judged by the engineer
31
White finger syndrome (WDF) is induced when hand
is subjected to vibration between 50 to 150 Hz vibration
32
Clearly noise level in work place
does not impair their ability to communicate and bearing on successful completion of the task
33
Noise in the workplace can have
short & long term negative effects
34
a task lighting should not be in the engineer line of sight
this will result in direct glare
35
Fumes can cause problems for engineers mainly as
result of inhalation, but they can also cause other problems, such as eye irritation
36
To reduce any feelings of discomfort when working within confined spaces
Good illumination and ventilation appropriate safety equipment, such as breathing apparatus or lines must be used when required.
37
If aircraft maintenance engineer has any doubt in any task he should consult a
written guidance such as maintenance manual
38
It is important to consult a written procedures and references and materials
when performing tasks on a complex systems
39
The danger of complacency can occur
if task is routine & repetitive
40
The main danger with repetitive tasks is that engineers may become so
practiced at such tasks that they may cease (stop) to consult the maintenance manual, or using a job cards
41
When performing repetitive visual inspection its beneficial to take short breaks
between discrete visual inspection tasks, as a defense against low arousal and possible overlooking of defects
42
When an engineer carrying out a visual inspection on aircraft, is most likely to make
the assumption that no effect will be found if the aircraft is new and has very low flying hours
43
Becoming a certified aircraft engineer requires
five years on the job experience
44
The engineer can perform a reliable visual inspection
by ensuring that the environment is suitable for the visual inspection task
45
Written communication (manuals) is an example of
asynchronous communication
46
The most common form of communication within the team of engineers in the hanger maintenance is
spoken communication
47
The effective communication within the organization depends
upon both the engineer and organization being actively involved in the communication process
48
The most important means of communication in the aircraft maintenance engineering
is written
49
a behavior that relies upon stored routine or motor programme that learned with practice is
Skill based behavior
50
Skill based error can be sub divided into
slips and lapses
51
A mistake occurs typically at
planning stage
52
Mistake can be sub divided into
rule based and knowledge based
53
Memory failures (forgetting) can occur in
encoding, storage or retrieval
54
A type 2 error when carrying out a visual inspection is defined as
a faulty item or defect is not detected
55
Dr.Reason statement “either you manage human error or human error will manage you “is to say
if you are not part of solution ,then you are part of the problem
56
The colored of danger signs that used in the hanger are
Red, black & white
57
Caution and danger signs used in the hanger should
be Positive recommendation such as, stay behind yellow line in the floor
58
When carrying out a risk assessment in the hanger
Some risks are acceptable
59
The effective warning signs must
inform employees what to do or not to do
60
Action to take in emergency are in order
assess the situation, make area safe ,assess causalities and call for help
61
Physical hazards may include
confined or closed areas
62

employees should be made aware that they exist and how to avoid them
63
Emergencies may include: an injury to
oneself or to a colleague
64
