9.1 Flashcards
What are human factors in aviation?
Study of human capabilities and limitations in the workplace.
Why is human factors training important for aircraft engineers?
Improves communication, work environment and overall safety standards in maintenance.
What percentage of aircraft accidents are linked to human error?
Around 70%
What major findings did the 1986 sears study reveal?
Maintenance and inspection deficiencies contributed to 12% of aircraft accidents.
How has the focus of aviation training evolved?
It shifted from technical skills to understanding human interaction with systems and equipment.
What does the term “ergonomics” refer to in aviations?
Refers to design and arrangement of equipment to fit human capabilities and limitations.
What is clinical psychology?
The study of application of psychological theory to understand, prevent, and relieve psychological distress while improving well-being.
How can clinical psychology assist individuals?
Helps to deal with stress, improve self-image, develop coping mechanisms and accept criticism.
What does experimental psychology focus on?
Basic behavioural processes such as learning, memory and perception.
What is anthropometry?
Study of human body dimensions and abilities, important for ensuring safety and comfort in aviation maintenance tasks.
How does computer science apply to aviation maintenance?
Ensures a comfortable, reliable workstation for documenting repairs and using software and test equipment efficiently.
What does a cognitive science examine?
Mechanisms of learning, decision-making and problem-solving, crucial for maintenance engineering’s facing high-pressure situations.
What is the role of safety engineering?
To ensure life-critical systems function properly even when components fail, emphasising a safe working environment in aviation maintenance.
How does medical science relate to human factors?
It addresses the health and well-being of individuals, considering physiological and biomechanics needs.
What do organisational psychologists focus on?
The relationship between people and work, including productivity, job satisfaction and employee development.
What is the aim of educational psychology?
To understand how people learn and design educational content that accommodates diverse learning styles.
What does industrial engineering study?
The organised approach to work, setting realistic standards, optimising workplace layout and analysing performance data.
What does the dirty dozen refer to?
Twelve common human rights for preconditions.
What developed the dirty dozen?
Gordon DuPont in 1993 while working for transport Canada.
Original purpose of the dirty dozen?
Part of an elementary training program for human performance in maintenance.
What happened to British airways flight 5390 on June 10, 1990
Left windscreen blew out at 17,500 feet, causing cabin decompression.
What was the reason for the cockpit window being blown out?
84 bolts undersized and 6 bolts too short, due to sleep deprivation, lack of managerial oversight and failure to wear corrective lens.
What happened to Excalibur airways A320 after a flap change?
The aircraft experienced an unwarranted roll to the right shortly after take off.
Reason for unwarranted turn on a320.
Lack of understanding and spoilers function and improper handover briefings due to unfamiliarity with the aircraft.
What happened to British mindlands Boeing 737-400 on febuary 23, 1995
Aircraft made an emergency landing at Luton airport after losing most of its engine oil in both engines.
Reason for engine oil leak?
After a boroscope inspection of the engine, the high pressure rotor drive covers were not refitted.
What happened to aloha airlines flight 243, on April 28, 1988?
The aircraft experienced explosive decompression leaning to an emergency landing after sustaining major damage.
Reason for aloha airlines flight decompression?
Engineers had recieved little formal training in Non-destructive inspection techniques and cracks from fastener holes were not detected.
What does Murphy’s law state?
If something can go wrong, sooner or later it will go wrong.
