AvSM Lesson 6 Flashcards
the amount of work to be done by someone or something.
WORKLOAD
are necessary for us to achieve our optimum performance,
arousal and alertness
demonstrates that our performance is directly related to the level of
arousal.
The Yerkes Dodson curve
Workload is a relatively subjective measure (experienced differently by different
people) and is affected by:
The nature of the task
The circumstances under which the task is performed
The individual and their situation
such as its physical and mental demands
the nature of the task
the standard of performance required, the time available to accomplish the task, and the prevailing environmental factors
The circumstances under which the task is performed
their skills both physical and mental; their experience, familiarity with the task; their health and fitness levels; and their emotional state.
The individual and their situation
occurs when there is a lot of work to be done.
WORK OVERLOAD
CAUSES OF HIGH WORKLOAD
Poor task planning;
Unexpected events;
Inadequate manning/high tempo
Changing task requirements;
System design/access problems;
System/task complexity
Ignoring some signals or responsibilities that are not seen as immediately relevant or necessary
Omission and Filtering
Limited Capability for the consideration of other possibilities, or to process information correctly
Reduced ability to think logically
delaying required actions in the hope you will be able to catch up as the task progresses
queuing
The tendency to automatically confirm a decision made, ignoring other information to the contrary
Confirmation bias
Near enough becomes good enough
Approximation
Referring to a previously well-learned procedure or action which may or may not be appropriate for the current task
Regression
result from simple or very
boring, repetitive tasks, or
indeed from a lack of tasks to do.
WORK UNDERLOAD
organize and execute work plans relating to all technical aspects of aircraft maintenance. Their goal would be to ensure minimum aircraft downtime and optimum use of facilities and
human resources.
maintenance planning
is the state of feeling very tired, weary or sleepy resulting from
insufficient sleep, prolonged mental or physical work, or extended periods of stress or anxiety.
Fatigue
two types of sleep related fatigue
aCUTE AND cHRONIC
this is generally only short-term and can be remedied
with a good night’s sleep
Acute
a longer-term problem, as there is usually a buildup of
sleep deprivation.
Chronic
is a brief moment sleep (generally between 2-30
seconds)
Micro sleep
Two common types of fatigue related errors in
maintenance are:
Memory failures
Failures to notice defects or problems
difficulty detecting defects during inspections, and may be less likely to
notice problems as a result of inattention or poor concentration.
Failures to notice defects or problems
