Accidents and engineering faults are insignificant and decreasing. significant and increasing. insignificant and increasing. Murphy's law is perpetuated mainly by violations. poor aircraft design. complacency. Murphy's law can be regarded as the notion: If something can go wrong it will. It can never happen to me. If something goes wrong I am certain to get the blame. A company's safety policy should be defined in CAP 716. the Maintenance Schedule. the Maintenance Organization Exposition. Which of the following is least associated with the study of human factors? Ergonomics. Health and Safety. Human error. The incident where a 737 lost oil from both engines is a direct result of poor design. human error. engine vibration. If a 737 had both engines serviced and lost oil from both engines in flight. This can be expected to happen statistically due to the number of aircraft in service. would be a direct result of human error. can be considered an acceptable probability. What do you do when someone is hypothermic? Warm them up. Feed them sweet things because of their diabetes. Give them a drink because of dehydration. The percentage of accidents attributable to aircraft maintenance and inspection causes is now less significant due to the introduction of more sophisticated aircraft. significant and rising. now less significant due to more advanced maintenance practices. What happened to contribute towards the incident in 1995 where a Boeing 737 lost oil pressure and had to divert? Both warning indications were faulty, due to crossed connections. The HP rotor drive covers of both engines had not been refitted after a boroscope inspection. The boroscope inspection had been inadequate. What is the most common cause of in-flight engine shutdown? Incomplete installation. Improper fault isolation, inspection or test. Foreign object damage. Most engineering related incidents are due to installing dirty connectors. installing components incorrectly. installing worn or old components. What causes the most aircraft accidents? Technical faults. Communication. Misunderstanding between ATC and pilot on approach. 70 - 80% of the total focusing ability of the eye is carried out by the iris. cornea. lens. At what distance should a person without hearing difficulties be able to hear an average conversational voice in a quiet room? 2 metres (6 feet). 3 metres (9 feet). 1 metre (3 feet). A perforated ear drum could occur if you were subjected to intermittent noise above 25 kHz. you blew your nose excessively. you were subjected to continuous noise below 8 kHz. How long is the short term memory good for remembering 7 items? 30 to 60 seconds. Up to 30 seconds. Above 60 seconds. What is white finger? A disorder of the finger which may occur through continuous use of pneumatic tools because of reduced blood flow. A reaction when the white blood cells die and contaminate the fingers. A skin disorder caused by extensive contact with oils and solvents. When someone is working in an enclosed space (such a fuel tank), another person should be outside the space in constant communication to provide instructions to the tradesman. to ensure compliance with the maintenance manual. for safety reasons. The scientific study of measurements of the human body is known as ergonomics. physiology. anthropometrics. How long can the aural reflex protect the ear from loud noise? 5 seconds. 15 seconds. 15 minutes. What part of the eye controls the amount of light that is allowed to enter the eye? The pupil. The iris. The cornea. Learning of a routine by repeated practice is known as cognitive learning. motor programming. episodic memory. The ear is used to detect speed. neither acceleration or speed. acceleration. Light enters the eye through the cornea. visual cortex. retina. To focus on a near object, the lens of the eye must be widened. flattened. thickened. Which type of memory is most susceptible to interference from external influences? Long term. Ultra short term. Short term. Peripheral vision is detected by the cones. fovea. rods. Extreme discomfort experienced by a maintenance engineer due to working in a confined space is known as claustrophobia. acrophobia. agoraphobia. What part of the eye is colour sensitive? The rods. The cones. The iris. What type of lens is used to overcome short sightedness? Concave. Bi-focal. Convex. The type of memory which is most easily influenced by a person's expectations of what should have happened is the long term memory. semantic memory. episodic memory. The inability for the eyes to accommodate sufficiently is known as presbyopia. hypermetropia. myopia. An aircraft maintenance engineer who wears glasses or contact lenses should not require their duties to be restricted providing they wear their glasses/contact lenses at all times they carry out their duties. have their duties restricted accordingly. not require their duties to be restricted providing they have frequent checks to ensure the adequacy of their glasses/ contact lenses. Ultra short term memory has a duration of about 10 to 20 seconds. 80 - 100 milliseconds. 2 seconds. What type of lens is used to correct long sightedness? Concave. Convex. Bi-focal. Visual Acuity is the ability to differentiate between different colours. to detect objects in the peripheral vision. of the eye to discriminate sharp detail at varying distances. The 'working memory' is long term memory. short term memory. ultra short term memory. Colour defective vision affects almost 1 in 10 of men. more women than men. almost 1 in 10 of women. At lower light levels, the visual sensing is performed mainly by the fovea. cones. rods. If an image formed on the retina of the eye is inverted relative to the viewers normal perception of the image, the viewer will become disoriented and dizzy. consciously mentally revert the image so as to make sense of his/her surroundings. behave and feel normal.
